RF PATTERN TESTING NAD - C 545BEE PCB TESTING POINTS DIAGRAM TESTING PROCEDURE (1) Load the test disc (Sony Test CD YEDS-7) and set the unit into PLAY mode. (2) Connect the scope to C7 (Pin 81 of IC1) and DGND (C32).
IMPORTANT NOTES INSTRUCTION FOR HANDLING OPTICAL SYSTEM BLOCK PICK-UP Electrostatic breakdown of the laser diode in the optical system block may occur due to a potential difference caused by electrostatic charge accumulated on clothing, human body, etc. A ground must be provided as follows to prevent any electrostatic charge during unpacking or repair work.

PRECAUTIONS WHEN CHANGING LASER PICK-UP When removing the pick-up assembly, short circuit the PCB tracks on the optical block as show in the drawing in order to protect the pick-up before removal. NOTE: Replacement pick-up assemblies are supplied with the PCB pattern already protected. DO NOT REMOVE THE SHORT CIRCUITS UNTIL YOU HAVE FINISHED FITTING THE PICK-UP.
