Releasing the MC Test Mode To release from this mode, press the I/1 *1 button or disconnect the power cord. DECK Test 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 the ASM signal twice. 6.Then the REW AMS 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.) x ALC Checking Procedure: 1.Enter the MC test mode. 2.Insert a tape into Deck B. 3.During Recording, Keep holding down the below keys. *2 + REC PAUSE/START ALC could keep ON while these keys keep being pressed, ALC could keep OFF while keys are released. Double Speed REC Mode Procedure: 1.Enter the MC test mode 2.Insert a tape into Deck B. 3.During Recording, keep holding down the below key.
