(3) Independent operation mode (Aging mode)
1 Short-circuit the jumper wires W205 and W4106 on the MD MAIN UNIT.
2 Independent operation mode (Aging mode) can be initiated by short-circuiting the S. REQ connector (pin 4) of the system bus (MD MAIN
UNIT : CN4702) with the GND connector (pin 14) for 3 seconds after AC power is applied.
In this mode, set the playback mode to All Repeat for aging. By setting the unit in All Repeat mode, the playback state can be maintained
for a long period of time.
• Key operations in Independent operation mode (Keys on the main unit are used.)
[ASES] Switches recording inputs (Digital/Analog)
[REC] Executes recording.
[PLAY] Executes playback.
[STOP] Stops recording/playback.
[EJECT] Ejects the disc.
[¢] Advances the track or CUE.
[4] Reverses the track or REV.
Note: For aging, set the playback mode to All Repeat in Independent operation mode.
• Recording input switching
By pressing the ASES key in Recording pause mode, you can switch the recording inputs.
Each time you press the key, digital and analog are selected in turn.
The REC LED steadily lights when digital is selected, and it flashes when analog is selected. The flashing cycle is slower than that of the PLAY
LED in Pause mode.
Note: If digital data cannot be locked when digital is selected, the REC LED flashes in the same cycle as that of the PLAY LED.
Note: The adjustment mode for the mechanism unit cannot be initiated from the Independent operation mode.
