barriers, insulation papers, shields, etc. 5. Before returning the serviced equipment to the customer, be sure to make the following insulation resistance test to prevent the customer from being exposed to a shock hazard. 1.1. Insulation Resistance Test 1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Before Repair and Adjustment Disconnect AC power, discharge Power Supply Capacitors C528, C529 and C960 through a 10 5W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
AC mains lead AM Loop antenna 5. 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). - Handling of traverse deck (optical pickup) 1.
Page 7
- 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. Caution : The static electricity of your clothes will not be grounded through the wrist strap.
6. Precaution of Laser Diode CAUTION: This unit utilizes a class 1 laser. Invisible laser radiation is emitted from the optical pickup lens. When the unit is turned on: 1. Do not look directly into the pick up lens. 2. Do not use optical instruments to look at the pick up lens. 3.
8. Disassembly 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.
1. Checking of the Main, Panel, Transformer, Deck and MP3 P.C.B. 2. Checking of Power P.C.B. - Main Component Replacement Procedures 1. Replacement of the Traverse Deck. 2. Replacement of the Power Amplifier IC. - Disassembly and assembly of the Traverse Unit - Disassembly and assembly of the Disc Tray Warning: This product uses a laser diode.
