TEST MODE

1) How to activate CD test mode

1) Press and hold the STOP button of P.W.B. Key and connect +12V to ACC/BACK UP.

2) How to cancel CD test mode

1) Disconnect +12V to ACC/BACK UP.

3) CD test mode functions

See fig-11 for the details of P.W.B. key and functioning buttons.

* Press the STOP key every time switching a mode.

* When a head unit is connected, the unit displays disc number and track number as it does ordinarily.

Note 1) If the focus search function is operated consecutively more than 10 minutes, the driver IC generates heat, the protection circuit is

activated to terminate CD mode. In this case, turn off the power, and wait for about 10 minutes to release heat before turning on the

switch.

Note 2) The System u-com is not compatible to all modes in TEST MODE. Therefore, an inserted disc does not work properly.

Note 3) Apply a disc change operation from the disc unit.
