AM Loop antenna 4. Handling Precautions For Traverse Deck The laser diode in the traverse deck (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 traverse deck (optical pickup). •...
• Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-static wrist strap to discharge the static electricity from your body. 2. Work table grounding Put a conductive material (sheet) or steel sheet on the area where the traverse deck (optical pickup) is placed, and ground the sheet.

1. Do not disassemble the optical pick up unit, since radiation from exposed laser diode is dangerous. 2. Do not adjust the variable resistor on the pick up unit. It was already adjusted. 3. Do not look at the focus lens using optical instruments. 4.
8. Operation Checks and Main Component Replacement Procedures “ATTENTION SERVICER” Some chassis components may have sharp edges. Be careful when disassembling and servicing. 1. This section describes procedures for checking the operation of the major printed circuit boards and replacing the main components.
Warning: This product uses a laser diode. Refer to caution statement “Precaution of Laser Diode. ACHTUNG: - Die Lasereinheit nicht zerlegen. - Die Lasereinheit darf nur gegen eine vom Hersteller speczifizierte Einheit ausgetauscht werden. 8.1. Checking Procedure for each major P.C.B. 8.1.1.

Step 4 Insert the gear with hexagonal wrench into the hole. Step 5 Rotate the hexagonal wrench in the direction of arrow (clockwise), and then open the disc tray fully. Step 6 Upset the CD changer unit again. Step 7 Release both the claws, and then draw the disc tray.
Page 26
Step 8 With forcing the left guide bar manually because the left guide bar interferes with claw, draw the disc tray. - Installation of the disc tray after replacement Step 1 Slide the drive rack fully in the direction of the arrow. Step 2 Holding the drive rack, not to move, install the disc tray.
Step 3 Align the drive rack with the drive gear. Step 4 Holding the disc tray manually, rotate the pulley gear in the direction of arrow. Step 5 Rotate the gear 5 or 6 times manually, and then push the disc tray. 9.
9.3. Cassette Mechanism Test (For error code H01, H02, H03, F01, F02) 1. Press “TAPE, DECK 1/2” to select Deck 2. 2. Load a cassette tape with the erasure prevention tab, remove from left side only and close the cassette holder. 3.
F16 ..etc). 9.5. To clear all Error code 1. Press “STOP/TUNE MODE” button for 5 seconds. 2. FL indicator shows “CLEAR” for 1 second and change to “T”. 9.6. How to get out from Self-Diagnostic function 1. Press “Power” button OFF. 9.7.
