Electrical method can only be performed when the mechanism is moved by rotating the Main Cam
Gear.
CAUTION:
If loading does not start in approx. 2 seconds after DC Power Supply is applied, DO NOT continue to
apply DC Power Supply. Instead, perform "Manual Method."
1. Remove the solder as shown and apply +10.0 VDC Power Supply (DC + to Portion "a," DC -
to Portion "c").
2. When the Loading Posts reach the fully unloaded position, remove the Power Supply.

Note:
Be careful not to let the DC Power Supply Unit GND contact the chassis GND. This may
damage the Loading Motor Drive IC (IC 2501).
Be sure to apply DC + to Portion "a" of Motor P.C.B.
If DC + is applied to Portion "b", the Loading Motor Drive IC (IC2501) may be damaged.
3. Rewind the tape into the cassette by turning the Center Clutch Unit counterclockwise.
