The signal reference potential, therefore, is connected to VREF(approx. 2.1V) instead of GND. If VREF and GND are connected to each other by mistake during adjustments, not only will it be impossible to measure the potential correctly, but the servo will malfunction and a severe shock will be applied to the pick-up. To avoid this, take special note of the following. Do not connect the negative probe of the measuring equipment to VREF and GND together. It is especially important not to connect the channel 1 negative probe of the oscilloscope to VREF with the channel 2 negative probe connected to GND. Since the frame of the measuring instrument is usually at the same potential as the negative probe, change the frame of the measuring instrument to floating status. If by accident VREF comes in contact with GND, immediately switch the regulator or power OFF. 2) Test Mode This mode is used for adjusting the CD mechanism module of the device. • After pressing the EJECT key, do not press any other key until the disk is completely ejected. • If the TUNE UP or TUNE DOWN key is pressed while focus search is in progress, immediately turn the power off (otherwise the actuator may be damaged due to adhesion of the lenses). B • Jump operation of TRs other than 100TR continues after releasing the key. CRG move and 100TR jump operations are brought into the “Tracking close” status when the key is released. • Powering Off/On resets the jump mode to “Single TR(91)”, the RF AMP gain setting to 0 dB, and the automatic adjustment value to the initial value. C • Always make sure the regulator is OFF when connecting and disconnecting the various filters and wiring required for measurements. • Before proceeding to further adjustments and measurements after switching regulator ON, let the player run for about one minute to allow the circuits to stabilize. • Since the protective systems in the unit's software are rendered inoperative in test mode, be very careful to avoid mechanical and /or electrical shocks to the system when making adjustment. D • The RFI and RFO signals are easy to oscillate because of a wide band. When observing them, insert a resistor of about 1 kΩ to the series. • This equipment will not guarantee the load ejection operation when the mechanical unit is turned upside down. In particular, if the ejection operation is incorrectly performed and recovery is disabled, the recovery is enabled by resetting a product or turning ACC off to on.

The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below. • Purpose : To check that the grating is within an acceptable range when the PU unit is changed. • Symptoms of Mal-adjustment : If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or taking a long time for track searching. • Method : • Measuring Equipment • Measuring Points • Disc • Mode B • Oscilloscope, Two L.P.F. • E, F, VREF • ABEX TCD-784 • TEST MODE CONTROL UNIT C L.P.F. E Xch 100kΩ 390pF VREF F 100kΩ 390pF VREF VREF Ych Oscilloscope L.P.F. E F D • Checking Procedure 1. In test mode, load the disc and switch the 5V regulator on. 2. Using the TUNE UP and TUNE DOWN buttons, move the PU unit to the innermost track. 3. Press key 4 to close focus, the display should read "91". Press key 3 to implement the tracking balance adjustment the display should now read "81". Press key 4. The display will change, returning to "81" on the fourth press. 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase difference is within 75° . Refer to the photographs supplied to determine the phase angle. 5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the mechanism should be judged to be at fault. • Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. E • Hint Reloading the disc changes the clamp position and may decrease the "wobble".
