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 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. TEST MODE ADJUSTMENT Head Angle Adjustment Head height alignment procedure • During FWD transport adjust screws F and F' so that line A of 2-LINE TAPE passes trough the center of the head shield plate (core center area) • During RVS transport adjust screws R and R' so that line B of 2-LINE TAPE passes trough the center of the head shield plate core (center area) • After the alignment above, reverse the transport direction and check the FWD alignment again. If it is deviated, perform alignment again.
