5 INTRODUCTION The Model AVOZ-B4-B pulse generator is designed for pulsing laser diode and other low impedance loads with rectangular pulses as high as +100V into 1Ω (i.e. +100 Amps) with 30 ns rise time. The pulse repetition frequency can vary from 1 Hz to 400 kHz, and pulse widths can vary from 100 ns to 2 us. The maximum duty cycle is 4%, and the maximum average output power is 400 Watts. The Model AVOZ-B4-B pulse generator is a voltage pulser. The current amplitude is determined by Ohm’s Law. That is, the current is the output voltage divided by the load resistance. The load resistance should be approximately 1Ω to attain a peak current of 100 A. An external DC power supply capable of supplying 0-110V and 0-4A is required. The voltage amplitude (and thus the current amplitude) is controlled by this DC power supply.

1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of pulse amplitude, pulse width, delay and PRF. (See http://www.avtechpulse.com/gpib). 2) For remote analog electronic control (0 to + 10V) of the amplitude, suffix model number with -EA. Electronic control units also include standard front-panel controls. Not available for the AVOZ-B4-B. 3) For operation at voltage amplitudes of less than 10% of full-scale, better results may be obtained by setting the amplitude near full-scale and increasing the load impedance accordingly. 4) For applications where additional resistance must be added in series with the device under test, Avtech recommends connecting multiple Ohmite OY-series (http://www.ohmite.com) ceramic composition resistors in parallel to create a high-power, low-inductance effective resistance. 5) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option. 6) The supplied test load is for low-duty-cycle basic operational tests only. The power rating of the load is 5 Watts. it is not capable of supporting the instrument's full maximum average output power. See http://www.avtechpulse.com/accessories/ for details about the AV-CTL series of test loads. 7) The AVOZ-B4-B requires a user-supplied 0 to 110V DC power supply that is capable of supplying the maximum average power output of the instrument (i.e., 400 Watts worst-case). The polarity of the power supply must be the same as that of the AVOZ-B4-B. The Xantrex ( http://www.xantrex.com/) XHR 150-7 is one example of a suitable power supply. 8) Add the suffix -TNT to the model number to specify the Internet control (Telnet and Web) option. 9) Multi-Contact (http://www.multi-contact.com or http://www.multi-contact-usa.com) ID/S6AR-N-B4S series, or similar. For mating cables, specify the -AK3 option, which includes two 1m cables (1 red, 1 black) with 6mm safety sockets, and two 6mm safety plug to M6 stud adapters (1 red, 1 black). 10) When operating into a 1.0 Ohm resistive load.
8 REGULATORY NOTES FCC PART 18 This device complies with part 18 of the FCC rules for non-consumer industrial, scientific and medical (ISM) equipment. This instrument is enclosed in a rugged metal chassis and uses a filtered power entry module (where applicable). The main output signal is provided on a shielded connector that is intended to be used with shielded coaxial cabling and a shielded load. Under these conditions, the interference potential of this instrument is low. If interference is observed, check that appropriate well-shielded cabling is used on the output connectors. Contact Avtech (
[email protected]) for advice if you are unsure of the most appropriate cabling. Also, check that your load is adequately shielded. It may be necessary to enclose the load in a metal enclosure. If any of the connectors on the instrument are unused, they should be covered with shielded metal “dust caps” to reduce the interference potential. This instrument does not normally require regular maintenance to minimize interference potential. However, if loose hardware or connectors are noted, they should be tightened. Contact Avtech (

1. POWER Switch. This is the main power switch. When turning the instrument on, there is normally a delay of 5-10 seconds before anything is shown on the main display. If the main menu does not appear after 30 seconds, turn off the instrument and leave it off for at least 60 seconds before applying power again. Allow 30 seconds before re-powering an instrument that has been switched off. If the power is switched more frequently than that, the turn-on delay may be longer (up to 20 seconds) as the internal software performs filesystem checks. 2. OVERLOAD Indicator. When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an internal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low impedance), the protective circuit will disable the output of the instrument and turn the indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 seconds after which the instrument will attempt to re-enable the output (i.e. light green) for about 1 second. If the overload condition persists, the output will be disabled again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is not a cause for concern. Note that the output stage will safely withstand a short-circuited load condition. 3. SYNC OUT. This connector supplies a SYNC output that can be used to trigger other equipment, particularly oscilloscopes. This signal leads (or lags) the main output by a duration set by the "DELAY" controls and has an approximate
17 amplitude of +3 Volts to RL > 50Ω with a pulse width of approximately 100 ns. 4. LIQUID CRYSTAL DISPLAY (LCD). This LCD is used in conjunction with the keypad to change the instrument settings. Normally, the main menu is displayed, which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenus in detail. 5. KEYPAD. Control Name MOVE CHANGE ×10 ÷10 +/EXTRA FINE ADJUST
Function This moves the arrow pointer on the display. This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. This changes the step size of the ADJUST knob. In the extrafine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer.

1. AC POWER INPUT. An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. One end of the detachable power cord that is supplied with the instrument plugs into this socket. 2. AC FUSE DRAWER. The two fuses that protect the AC input are located in this drawer. Please see the “FUSES” section of this manual for more information. 3. DC FUSES. These two fuses protect the internal DC power supplies. Please see the “FUSES” sections of this manual for more information. 4. GATE. This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, depending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). When set to active high mode, this input is pulleddown to ground by a 1 kΩ resistor. When set to active low mode, this input is pulledup to +5V by a 1 kΩ resistor. 5. TRIG. This TTL-level (0 and +5V) logic input can be used to trigger the instrument, if the instrument is set to triggering externally. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Depending on the length of cable attached to this input, and the source driving it, it may be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper transmission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thru
19 50 Ohm terminator is suggested for this purpose.) 6. GPIB Connector. A standard GPIB cable can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on GPIB control. 7. RS-232 Connector. A standard serial cable with a 25-pin male connector can be attached to this connector to allow the instrument to be computer-controlled. See the “Programming Manual for -B Instruments” for more details on RS-232 control. 8. Network Connector. (Optional feature. Present on -VXI units only.) This Ethernet connector allows the instrument to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. See the “Programming Manual for -B Instruments” for more details. 9. AMP Connector. This connector (if present) is not used in the AVOZ-B4-B-P. 10. OUT. This is the main positive output. The AV-CLZ1-60 transmission line plugs into this DB-37 female connector. Pins 1-19 (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connected to ground. Caution: Voltages as high as 100V may be present on the pins 1-19 of this output connector. Avoid touching these conductors. Ensure that any cable, load, or system connecting to this connector shields the high-voltage areas from the user. 11. DC IN (+) Connector. This power input connector must be connected to the positive (+) output of the user-supplied external DC power supply. This connector will accept 6 mm safety sockets, or 4 mm "banana" plugs. (6 mm safety sockets will have considerably higher current capability). Beware that the 6 mm cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it. Caution: Voltages as high as 110V may be present on this input connector. Avoid touching these conductors. Ensure that any cable, load, or system connecting to this connector shields the high-voltage areas from the user. 12. GND (-) Connector. This power input connector must be connected to the negative (-) output of the user-supplied external DC power supply. This connector will accept 6 mm safety sockets, or 4 mm "banana" plugs. (6 mm safety sockets will have considerably higher current capability). Beware that the 6 mm cables "lock" into the mating adapters. To release the lock, push the cable inwards FIRST, and THEN pull it out of the adapter. The cable will not be released if you simply pull on it.
20 GENERAL INFORMATION - PULSE GENERATOR TIMING BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an external TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC. The OUT channel is the signal that is applied to the device under test. Its amplitude and pulse width are variable. The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. When the delay is set to a positive value the SYNC pulse precedes the OUT pulse. These pulses are illustrated below for a positive delay, and internal triggering: SYNC OUT (generated by the internal oscillator)

As before, if the delay is negative, the order of the SYNC and OUT pulses is reversed. TRIGGER MODES This instrument has four trigger modes: •
Internal Trigger: the instrument controls the trigger frequency, and generates the clock internally.
•
External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.
•
Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.
•
Hold Trigger: the instrument is set to not trigger at all.
These modes can be selected using the front panel trigger menu, or by using the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GATE connector. The instrument can be set to stop triggering when this input high or low, using the frontpanel gate menu or the appropriate programming commands. This input can also be set to act synchronously or asynchronously. When set to asynchronous mode, the GATE will disable the output immediately. Output pulses may be truncated. When set
22 to synchronous mode, the output will complete the full pulse width if the output is high, and then stop triggering. No pulses are truncated in this mode.
23 GENERAL INFORMATION - OPERATING INTO A LOAD AMPLITUDE CONTROL The Model AVOZ-B4-B pulse generator is a voltage pulser. The current amplitude is determined by Ohm’s Law. That is, the current is the output voltage divided by the load resistance. More specifically: IOUT = (VSETTING – VDIODE) / R, where VSETTING is the set amplitude of the attached DC power supply, V DIODE is the diode voltage, and R is the series resistance (including any series resistance in the diode itself). R is normally 1Ω; it should not be smaller than this. Avtech recommends connecting multiple Ohmite OX or OY-series or RCD RSF2B resistors in parallel to create a high-power, low-inductance effective resistance. SELECTING THE SERIES RESISTANCE The best waveforms will normally be obtained if the amplitude is set between 20% and 100% of the maximum rating (i.e., 20V to 100V), and if the load resistance R is chosen to be between 1.0 and 1.6 Ohms. It should never be less than 1.0 Ω, or the instrument may be damaged. For applications requiring less than the maximum possible current, best results may be obtained if R is approximately 1.6 Ω, because this slight increase in the load resistance will result in a faster transition times. However, the load resistance should not be increased beyond 1.6 Ω, or the transmission line mismatch between the output transmission line (which has a characteristic impedance of Z 0 = 1 Ω) and the load may introduce significant ringing. If the resistance of the device under test (DUT) is significantly higher than 1.6 Ω, resistance should be added in parallel with the DUT so that the total equivalent resistance is 1.0 to 1.6 Ω. Higher load resistance may cause the fall time to degrade severely. OUTPUT CONNECTIONS The main output is provided on a rear-panel DB-37 female connector. Pins 1-19 of this connector (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connected to ground. An AV-CLZ1-60 transmission line is supplied with the instrument. One end plugs into the rear-panel connector. The other end is terminated with a DB-37 male connector.
24 Pins 1-19 of this connector (the upper row) are connected to the signal out, and pins 20-37 (the lower row) are connected to ground. The cable is reversible - either end can be plugged into the rear panel. This cable can be ordered separately, as model AVCLZ1-60. (Lengths longer than 60 cm are also available - see http://www.avtechpulse.com/transmission/av-clz1 for details.) The user may connect a load to the end of the AV-CLZ1-60 transmission line using a load that has a DB-37 female connector. To construct your own connectorized load, consider using a Norcomp 172-037-201-001 DB-37 female connector with solder cup pins. This is readily available from Digi-Key (http://www.digikey.com, stock number 137F-ND). Care must be taken to construct the connectorized test load to conform to local safety standards. High voltages (up to 100V, approximately) will be present on the load during normal operation. Pins 1-19 short be connected together to provide the signal output, and pins 20-37 should be connected together to provide the ground. It may be simpler to modify the supplied test load. The supplied test load has this connector pre-installed, and a safety enclosure is provided. This test load is described in the next section. Caution: Voltages as high as 100V may be present on the pins 1-19 of the output connector. Avoid touching these conductors. Ensure that any cable, load, or system connecting to this connector shields the high-voltage areas from the user. USING THE SUPPLIED TEST LOAD (AV-CTL1-ENC) FOR LOW-POWER TESTS The supplied test load consists of a DB-37 female connector mounted on the lid of a small aluminum box chassis. Inside the chassis, an 8 mm by 50 mm circuit board is sandwiched between the two rows of solder cups on the rear of the connector. Four Ohmite OY-series 3.9 Ohm resistors are connected in parallel between the two rows of solder cups. This provides a total resistance of 3.9 Ω / 4 ≈ 1.0 Ω. Two unused SMA connectors are provided for making connections through the chassis wall, if desired. A 5/16" hole, plugged with a screw is also provided. The screw may be removed to provide an access hole to the interior of the chassis. Due to the presence of high voltages on the output (up to 100V, approximately), the lid should be installed on the aluminum chassis so that users can not physically touch the load. The test load has a maximum power dissipation rating of 5 Watts. Take care not exceed this! The AVOZ-B4-B can deliver up to 400 Watts of output power. This test load can be ordered separately, as model AV-CTL1-ENC. It can also be ordered with no resistors installed, as model AV-CTLX-ENC (or AV-CTLX, if the aluminum safety enclosure is not wanted). The basic mechanical connection scheme for the AV-CTL1-ENC is shown below:

HIGHER POWER LOADS The supplied test load is only useful for power dissipations of 5 Watts or less. For higher power applications, a high-power resistance can be constructed using many (20 to 100) medium-power resistors. It is essential that low-inductance resistors be used. Many non-inductive, medium power resistors should be used in parallel to both lower the total inductance and to boost the total power rating. The Ohmite OY series (www.ohmite.com) or the RCD RSF2B series (www.rcd-comp.com) are appropriate. (The Ohmite OY resistors are extremely rugged, but the less rugged RCD RSF2B resistors have a lower temperature coefficient.) For factory tests at maximum duty cycle, one-hundred 100 Ω, 2 Watt Ohmite OY-series resistors are connected in parallel, and are submersed in water for extra cooling. The water cooling allows this load to dissipate up to 400 Watts. This arrangement is shown below:

ALARMS The AVOZ-B4-B-P has several protective circuits. Various protection circuits will trip if: 1) The DC power supply voltage exceeds +110V. 2) The DC power supply voltage is negative. 3) The output circuitry overheats. If any of these protection circuits are tripped, the output will be disabled. An audible alarm buzzer will be heard under the first two conditions (improper DC voltages). The buzzer may sound briefly when the power is first switched on. This is normal, and not a cause for concern.

The diagram above shows how high-impedance oscilloscope probe can be used to observe the waveform. However, since the load impedance is so low (1 Ohm), a 50 Ohm measurement system like that shown in the diagram below can also be used to observe the load waveform. An attenuator should be used to avoid damaging the oscilloscope input, since the load voltage can be as high as 100V. (Two SMA connectors are present in the AV-CTL1-ENC test load, and either can be used to connect the 50 Ohm coaxial cables through the chassis wall.)

There are several key points to note. As explained above, a resistance should be added in series with the diode load, to limit the maximum current. This resistance may also be used to monitor the current through the diode current. If connected as shown above, the resistor voltage displayed on the oscilloscope is directly proportional to the diode current. It is essential the low-inductance resistors be used. Multiple noninductive, medium power resistors should be used in parallel (for instance, four 3.9 Ohm 2W resistors). The Ohmite OY series (www.ohmite.com) or the RCD RSF2B series (www.rcd-comp.com) are appropriate. It is also recommended that a low-capacitance, high-voltage, ultra-fast Schottky rectifier diode be connected for reverse-bias protection, especially for sensitive or costly devices under test. The APT (www.advancedpower.com) APT15S20K is an example of a suitable diode. Note, however, that the capacitance added by the protection diode may degrade the output rise time slightly. LENZ’S LAW AND INDUCTIVE VOLTAGE SPIKES This instrument is designed to pulse resistive and diode loads and will exhibit a large output spike when used to drive a load with significant inductance (as predicted by LENZ'S LAW). For this reason the load should be connected to the output using low inductance leads (as short as possible and as heavy a gauge as possible).
29 The voltage developed across an inductance L (in Henries), when the current is changing at a rate given by dILOAD/dt (in Amps/sec), is: VSPIKE = L × dILOAD/dt. For this reason, the length of leads used to connect the load to the circuit board should be kept extremely short ( < 0.5 cm). ATTACHING AND DETACHING LOADS To avoid damaging the loads connected to main outputs, the loads should only be connected to or removed from the instrument when the instrument is off. Do not connect loads when the instrument is on and the output amplitude is not zero. This can cause sparking. MEASURING OUTPUT CURRENT Two basic methods can be used to observe the current waveform through the load. The first is to observe the voltage waveform across the resistance present in the load. If the resistance is non-inductive, the voltage waveform will be directly proportional to the current waveform (Ohm's Law). Keeping the parasitic inductance low is critical for reliable measurements. If a diode is connected in series with the resistance, it may be advantageous to ensure the diode is placed before the resistance, so that one end of the resistance is grounded. This will eliminate the need for differential voltage measurements. This method is shown in the "TEST ARRANGEMENT" section above. Alternatively, a high-speed current probe or current transformer can be used to observe the current waveform. One possible model is the Pearson 2878 current transformer (http://www.pearsonelectronics.com). Unfortunately, it may be necessary to introduce a significant lead length (i.e., inductance) to pass the conductor through the transformer.
30 START-UP CHECK-LIST FOR LOCAL CONTROL 1. Connect the supplied test load (AV-CTL1-ENC) to the rear-panel of the mainframe, using the AV-CLZ1-60 cable. 2. Connect a cable from the SYNC OUT connector to the TRIG input of an oscilloscope. Set the oscilloscope to trigger externally. 3. Connect an oscilloscope probe to the signal side of the resistors in the test load. It may be necessary to connect the probe using the SMA feed-throughs on the test load enclosure. On the oscilloscope, set the channel A vertical scale to 20 V/div, and the horizontal scale to 100 ns/div. (A 50 Ohm measurement system, without a high impedance probe, can also be used if desired. This may be more mechanically convenient. See the "TEST ARRANGEMENT" section for details.) 4. Connect the DC power supply to the two rear-panel connectors (DC IN + and GND -). The DC power supply must be capable of supplying up to 110V and 4A. 5. Turn on the instrument. The main menu will appear on the LCD. 6. To set the instrument to trigger from the internal clock at a PRF of 1 kHz: a) The arrow pointer should be pointing at the frequency menu item. If it is not, press the MOVE button until it is. b) Press the CHANGE button. The frequency submenu will appear. Rotate the ADJUST knob until the frequency is set at 1 kHz. c) The arrow pointer should be pointing at the “Internal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 7. To set the delay to 100 ns: a) Press the MOVE button until the arrow pointer is pointing at the delay menu item. b) Press the CHANGE button. The delay submenu will appear. Rotate the ADJUST knob until the delay is set at 100 ns. c) Press CHANGE to return to the main menu. 8. To set the OUT pulse width to 500 ns: a) Press the MOVE button until the arrow pointer is pointing at the “PW” menu item.
31 b) Press the CHANGE button. The pulse width submenu will appear. Rotate the ADJUST knob until the pulse width is set at 500 ns. c) The arrow pointer should be pointing at the “Normal” choice. If it is not, press MOVE until it is. d) Press CHANGE to return to the main menu. 9. At this point, nothing should appear on the oscilloscope. 10.To enable the output: a) Press the MOVE button until the arrow pointer is pointing at the output menu item. b) Press the CHANGE button. The output submenu will appear. c) Press MOVE until the arrow pointer is pointing at the “ON” choice. d) Press CHANGE to return to the main menu. 11.To change the OUT output amplitude: a) Slowly increase the output voltage of the attached DC power supply up to +100V. b) Observe the oscilloscope. You should see 500 ns wide, 100V pulses on the probe connected to the main output. c) Press CHANGE to return to the main menu. 12.Try varying the pulse width, by repeating step (7). As you rotate the ADJUST knob, the pulse width on the oscilloscope will change. It should agree with the displayed value. 13.This completes the operational check.
32 PROGRAMMING YOUR PULSE GENERATOR KEY PROGRAMMING COMMANDS The “Programming Manual for -B Instruments” describes in detail how to connect the pulse generator to your computer, and the programming commands themselves. A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent to the instrument after power-up: *rst trigger:source internal frequency 10 Hz pulse:width 100 ns pulse:delay 1 us output on
(resets the instrument) (selects internal triggering) (sets the frequency to 10 Hz) (sets the pulse width to 100 ns) (sets the delay to 1 us) (turns on the output)
For triggering a single event, this sequence would be more appropriate: *rst trigger:source hold pulse:width 100 ns output on trigger:source immediate trigger:source hold output off
(resets the instrument) (turns off all triggering) (sets the pulse width to 100 ns) (turns on the output) (generates a single non-repetitive trigger event) (turns off all triggering) (turns off the output)
To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIG connector, use: *rst trigger:source external pulse:width 100 ns pulse:delay 1 us output on
(resets the instrument) (selects internal triggering) (sets the pulse width to 100 ns) (sets the delay to 1 us) (turns on the output)
These commands will satisfy 90% of your programming needs.
33 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available commands is given below.

35 MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removing the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpowered for 10 minutes before opening the instrument. This will allow any internal stored charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech ([email protected]) to arrange for the instrument to be returned to the factory for repair. Service is to be performed solely by qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. RACK MOUNTING A rack mounting kit is available. The -R5 rack mount kit may be installed after first removing the one Phillips screw on the side panel adjacent to the front handle. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused outputs should be terminated with shielded coaxial terminators or with shielded coaxial dust caps, to prevent unintentional electromagnetic radiation. All cords and cables should be less than 3m in length.
36 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require replacement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compressed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommended.
