TEST MODE
1. How to enter the test mode
•Reset the unit while holding the “FM”key and preset “6”key.
•All indication segments go ON at the beginning of the test mode.
2. How to check the test mode
•Cancel the blank skip (B.S).
•Push the “ATT”key.
•The eject function works.
3. How to release the test mode
•Simply reset the unit.
•(NOTE)The test mode is not canceled byACC OFF, power OFF, momentary power
down or the panel off.
4. Audio adjustment
•Set the volume level to -10dB (which is shown as “30”on the display).
•Loudness OFF.
•The BASS/TREBLE and BALANCE/FADER can be set to the full-boost/full-cut and
full-front/full-rear each by pressing the “Track UP”/ “Track DOWN”keys.
•Sound coordination doesn't appear for the feed.
