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. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 6 ADJUSTMENT/EINSTELLUNGEN (MECHA.) 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) 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.
