MECHANISM DESCRIPTION

2.1. DESCRIPTION OF MANUAL OPERATION

Naturally, this mechanism operates under microprocessor control, and manual operation may cause a trouble.
However, manual operation will be necessary for repair, etc. and in such a case, perform as follows.

2.1.1 Position in Each Mode

The mode can be oonfirmed from the fact that which marking written on the REEL PWB Ass'y the tab attaching to the
OP PLATE Ass'y points out.

2.1.2 Manual Operation in Each Mode

To move a mechanism manually in each mode, rotate the D GEAR by hand. (In such a case, wear gloves for easier
operation and for protection of GEARS.)

In a manual operation, take extreme care not to damage GEARS, and to prevent later malfunction of mechanism.

To change mode from EJECT to other mode, rotate

the D Gear in CCW direction as shown in figure.
