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 fullfront/full-rear each by pressing the "Track UP" / "Track DOWN" keys. · Sound coordination doesn't appear for the feed.

ADJUSTMENT/EINSTELLUNGEN (MECHA.)
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)
(2-LINE TAPE)
· 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)

Einstellung des Kopfwinkels
Vorgehensweise bei der Kopfhöhen-Einstellung
· Während des Bandlaufs in Vorwärtsrichtung die Schrauben F und 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 R und 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)
