TEST MODE There are two methods to perform operation check using test mode. One method uses the head unit. The other method uses the repair jig. Because different operation buttons must be used for entering the operation modes and there are cases that unit does not run at all, in the method that uses the head unit, the method using the repair jig is described as follows; 1. How to start up the CD test mode Connect the P.W.B Key in accordance SERVICE JIG AND TOOLS step (6).
