TEST MODE1. 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 release the test mode• Simply reset the unit.• (NOTE) The test mode is not canceled by ACC OFF,

power OFF, momentary power down or the paneloff.

3. Audio adjustment• Set the volume level to -10dB (which is shown as

"30" on the display).• Loudness OFF.• The BASS / TREBLE and BALANCE / FADER con-

trols can be set to the full boost / full cut and full right/ full left and full front / full rear respectively by press-ing the Track Up / Track Down keys.

• Sound coordination doesn't appear for the Audiomode feed.
