Handling Precautions for MD Unit The laser diode in the MD unit (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So be careful of electrostatic breakdown during repair of the MD unit (optical pickup). 2.1. Handling of MD Unit (optical pickup) 1. Do not subject the MD unit (optical pickup) to static electricity as it is extremely sensitive to electrical shock. 2. To protect the breakdown of the laser diode, an anti-static shorting pin is inserted into the flexible board (FPC board). Refer to Fig. 2-1. 3. Take care not to apply excessive stress to the flexible board (FPC board). 3 Fig. 2-1. 2.2. Grounding for electrostatic breakdown prevention 2.2.1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body. Refer to Fig. 2-2. Fig. 2-2. 2.2.2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the MD unit (optical pickup) is placed, and ground the sheet. Refer to Fig. 2-3. Fig. 2-3. Caution: The static electricity of your clothes will not be grounded through the wrist strap. So take care not to let your clothes touch the MD unit (optical pickup). 3.

Measurements and Adjustments Note: Because this unit uses the optical magnetic recording, the unit outputs over 10 times more laser than a CD player does. In adjustment mode, the laser is always being output. Therefore, be especially careful not to look laser beam directly or to touch the laser beam when adjusting the unit and checking its operation. 17.1. Necessary instruments - Laser power meter (LE8010) - Test disc (Pre-mastered disc RFKV0006 or RFKV0014) - Recordable disc available on sales route / (with music recorded) - Insulated driver for adjustment such as a ceramic driver - Extension cable kit (RFKZJMD100EK) - Remote control transmitter 17.2. Set to the unit to adjustment mode 1. Turn the power ON. 2. With no MD loaded in the unit, press and hold the STOP button ( ) for at least 2 seconds. And then while still pressing the STOP button ( ), press the F.SEARCH button ( ) for at least 2 seconds. The unit is set to the self-diagnostic function and is displayed “MD TEST”. Refer to Fig. 17-1. Fig. 17-1. Caution on optical pickup: - The optical pickup and the magnetic head are structured precisely; therefore, they are very fragile. Be careful not to touch them with the edge of laser power meter. - The sensor of the laser power meter is a very fine part. Be careful not to touch it to the optical pickup lens. - The focus point of the laser reaches to 180°C. Therefore, avoid using laser power for a long time because the sensor of the laser power meter may be burned. 41 - Do not allow the write power to even momentarily reach or exceed 5.5 mW. Doing so will result in damage to the optical pickup. - Do not set the unit to the laser power adjustment mode with the MD loaded. Doing so may result in damage to the MD. 17.3. Laser power adjustment Adjust each laser power: read power for reading (play) and write power for writing (record). Caution: 1. About handling the MD unit - The magnetic head is precision unit and is very fragile. Do not deform it. - Laser diode in the optical pickup may be destroyed by the static electricity generated in your clothes or body. Be especially careful with the static electricity. - The optical pickup is structured extremely precisely. Do not subject to the strong impact or shock. Do not touch the lens. 2. About handling the magnetic head When replacing the magnetic head, do not tighten the mounting screw (RHD17022) too firmly. If the screw is tightened too much to deform the resin, the position of the head is moved, and this affects its recording operation. Recommended torque for mounting screw: / 700±100 g cm Reference: This is the same force as using a screwdriver with a 15-mm diameter grip, you fasten the screw naturally with your thumb and index finger. 3. About the driver for adjusting laser power Use only insulated driver such as a ceramic driver. With the metal driver, it is not possible to adjust properly because of induction noise. Also, if it short-circuits with the chassis, it may destroy or damage the laser diode. Recommended driver: VESSEL 9000 1.8-30 / (Ceramic driver) 17.3.1. Adjustment Procedure 1. With no MD loaded in the unit , press “1” on the remote control transmitter. “RAM LASER” will be displayed to indicate the read power adjustment mode. 2. Slide the sensor cover of the laser power meter. / Refer to Fig. 17-2. Fig. 17-2. 3. Position the sensor of the laser power meter directly above the optical pickup. Refer to Fig. 17-3. Or load the cartridge of the laser power meter into the MD mechanism. Refer to Fig. 17-4. Fig. 17-3. 42 Fig. 17-4. 4. Confirm that the reading of the laser power meter is within the specified range. If it is not within the specified range, adjust by turning VR1. Refer to Fig. 17-5. Fig. 17-5. Specified range (read power): 600 µW or lower Caution: Proceeding on to the subsequent adjustment procedure with the read power exceeding 600 µW will result in damage to the optical pickup. 5. Press “2” on the remote control transmitter. “WRITE LASER” will be displayed to indicate the write power adjustment mode. 6. Confirm that the reading of the laser power meter is within the specified range. If it is not within the specified range, adjust by turning VR1. Refer to Fig. 17-5. Specified range (write power): 4.8 mW±0.1 mW Caution: Do not allow the write power to even momentarily reach or exceed 5.5 mW. Doing so will result in damage to 43 the optical pickup. 7. Press “3” on the remote control transmitter. “ROM LASER” will be displayed to indicate the ROM data confirmation mode. 8. Confirm that the reading of the laser power meter is within the specified range. Specified range (ROM data laser power): / 540 µW ~ 660 µW 9. Press “1” on the remote control transmitter. “RAM LASER” will be displayed to indicate the RAM data confirmation mode. 10. Confirm that the reading of the laser power meter is within the specified range. Specified range (RAM data laser power): / 540 µW ~ 660 µW If the reading in either step 8 or 10 above is not within the specified range, first switch off the power, and then reset the unit to the adjustment mode and repeat the adjustment procedure. 11. Turn the power OFF. 18. Replacement Parts List Notes: - Important safety notice: Components identified by mark have special characteristics important for safety.
