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 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.

Einstellung des Kopfwinkels
Vorgehensweise bei der Kopfhöhen-Einstellung
• Während des Bandlaufs in Vorwärtsrichtung die Schrauben Fund F' so
einstellen, daß die Linie A eines 2-Linien-Bands (2-LINE TAPE) durch
die Mitte der Kopfabschirmplatte (Zentrum des Mittelbereichs) verläuft.
• Während des Bandlaufs in Rückwärtsrichtung die Schrauben Rund R'
so einstellen, daß die Linie B eines 2-Linien-Bands (2-LINE TAPE)
durch die Mitte der Kopfabschirmplatte (Zentrum des Mittelbereichs)
verläuft.
• Nachdem die obige Einstellung abgschlossen ist, die Bandlaufrichtung
umkehren und die Ausrichtung in Vorwärtsrichtung noch einmal
überprüfen. Wenn eine Abweichung festgestellt wird, ist diese
Einstellung zu wiederholen. (Verwendetes Band: SCC-1659, hergestellt
von A-BEX)
Head Angle Adjustment
Head height alignment procedure
• During FWD transport adjust screws Fand 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 Rand 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. (Tape
used : SCC-1659, manufactured by A-BEX)
