Note: Use following buttons in the test mode.
no mark: Button of Tape unit (TC-S9)
*1 : Button of amplifier unit (TA-S9D)
*2 : Button of DVD/video CD/CD unit (DVP-S9)
[MCTest Mode]
Enter the MCTest Mode
Procedure:
1. Press the I/1*1button to turn the power on.
2. While pressing the both [PLAY MODE]*2and [ ]*2buttons,
press the [DISC 3]*2button.
3. “GROOVE” indication blinks on the fluorescent indicator tube
in the midst of MC test mode.
Releasing the MCTest Mode
To release from this mode, press the I/1*1button or disconnect
the power cord.
[DECKTest Mode]
In the DECK test mode, it operates as follows.
Cancellation of the linear mute of DOLBY IC (IC301)
• It become cancellation automatically when it is possible to en-
ter a MC test mode.
AMS Checking
Procedure:
1. Enter the MC test mode.
2. Insert a test tape AMS-110A or AMS-120 to Deck A.
3. Set TAPE A function.
4. Press the [DVD SYNC] button to enter the AMS test mode.
5. After a tape is rewound first, the FF AMS is checked, and the
mechanism is shut off after detecting theASM signal twice.
6. Then the REWAMS is checked and the mechanism is shut off
after detecting the AMS signal twice.
7. When the check is complete, a message of either OK or NG
appears.
(To check an AMS of the B deck, select TAPE B function.
After that, press [DVD SYNC].)

1. Demagnetize the record/playback head with a head
demagnetizer.
2. Do not use a magnetized screwdriver for the adjustments.
3. After the adjustments, apply suitable locking compound to the
parts adjust.
4. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
5. The adjustments should be performed in the order given in
this service manual. (As a general rule, playback circuit ad-
justment should be completed before performing recording
circuit adjustment.)
6. The adjustments should be performed for both L-CH and R-
CH.
7. Switches and controls should be set as follows unless other-
wise specified.
8. Please refer to “SERVICING NOTES” (page 3) before adjust-
ments.
