1) Connect 62 pin (test) of IC701 (LC72358N-9910) on  
MAIN C.B to the 31 pin (VDD) by cable.  
Correct between MAIN C.B. and CD mechanisms by extension jigs when checking CD mechanism  
(TN-CCD1001-113J) operation.  
(Refer to the following figure.)  
2) Connect wire of ACC (red) and BACKUP (yellow) of power supply/speaker connector to DC+12V,  
then connect Ground (black) to -.  
When CD test mode is started, all displays will be lighted as shown in the following figure.  
1-2 How to cancel CD Test Mode  
1) Disconnect the cable of 62 pin (test) and 31 pin (VDD) of the MAIN C.B
