Instructions for Handling Semi-conductors Electrostatic breakdown of the semi-conductors may Fine Tip Soldering Iron occur due to a potential difference caused by electro- static charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1MΩ) that is prop- erly grounded to remove any static electricity that may be charged on the body.
PREPARATION FOR SERVICING How to Enter the Service Mode About Optical Sensors Caution: An optical sensor system is used for the Tape Start and End Sensors on this equipment. Carefully read and follow the instructions below. Otherwise the unit may operate erratically. What to do for preparation Insert a tape into the Deck Mechanism Assembly and press the PLAY button.
Be careful not to break them. 1. Remove five Screws (S-2), two Screws (S-3): [6] Main CBA TVCR-210(C), three Screws (S-3): TVCR-610(C), and Screw (S-4). Then, slowly lift the VCR Chassis [7] Cylinder Shield Unit (Deck Assembly, Jack CBA and Main CBA) up.
