For U.S.A., Canada & Europe model SU PP SERVICE MANUAL MODEL DN-C680 LE ME NT Ver. 1 CD PLAYER We have two version of DN-C680. The new version of DN-C680 is replaced discontinued parts of the old version. (CD mechanism, microprocessor and D/A converter etc.) Serial number of new version are renumbered from *****50001. This service manual is supplement for new version of DN-C680 and only mentioned difference between old and new version.
DN-C680 SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

DN-C680 4 CONFIRMING THE SERVO CAUTION: The Optical Pick-up used for CD player may invite defection by an external noise, such as electrostatic, etc., please pay the following attention. 1. Use a conductive mat on a working table to avoid electrostatic damage. 2. A working personnel should use a wrist strap to ground human body. 3. Tools, etc., specially for a soldering iron must use with its tip grounded and without leakage of electricity.
DN-C680 5 2. What is Service Program Service program is a special program intended for confirming servo. 3. Contents of Service Program While simultaneously pushing the STANDBY/CUE and PLAY/PAUSE buttons, turn the power on. (TRACK Indication “00”) After actuating the service program, select an aiming process number with the SELECT KNOB, PITCH button, and TIME button, and push the PLAY/PAUSE button to execute processing, The process number is then displayed on the TRACK indication portion. Work No.
