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 panel off. 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 controls can be set to the full boost / full cut and full right / full left and full front / full rear respectively by pressing the Track Up / Track Down keys. • Sound coordination doesn't appear for the Audio mode feed. Set the controls and switches as follows.
