MICROCOMPUTER'S DESCRIPTION ADJUSTMENT

TEST MODE1. To enter test mode

While holding the “FM” key and preset “6” key, reset the unit.All indication segments are ON at the beginning of test mode.

2. To release test modeSimply reset the unit.(NOTE) The test mode is not canceled by ACC OFF, powerOFF, momentary power down.

3. MD receiver test mode specificationPressing the “Track Up” key jumps between tracks in thefollowing order.No.7 → No.2 → No.13 → No.23 → No.30 → No.34 → No.7(Same as the beginning)Pressing the “Track Down” key jumps to the previous trackto the being played.Pressing the preset “1” key jumps to No.28 track. Againpressing the preset “1” key jumps to No.22 track.

4. Audio adjustmentThe volume is set to -10dB (which is shown as 30).Loudness is OFF. CRSC becomes OFF regardless of thefunctional excuse, too.The BASS / TREBLE and BALANCE / FADER controls canbe set to the full boost / full cut and full front / full rear and fullright / full left respectively by pressing the “Track Up” / “TrackDown” keys.Sound coordination(Kex / ec4 / dB) doesn't appear for theAudio mode feed.
