Manually removing the cassette tape
If a loaded cassette tape cannot be ejected due to a failure in the
electrical circuitry, take the cassette tape out using the following
procedure. However, this method consists of a forced driving of
the loading motor. Therefore, the following description assumes
that there is no trouble in the mechanism operations.
(1) Unplug the power plug from the power outlet, then remove
the top cover.
(2) Apply 3 V DC to the electrodes (Red wire: + pole. Brown
wire: - pole) on the upper part of the loading motor to per-
form the unloading operation so that the pole base assem-
blies are returned on the inner side of the tape. At this time,
the exit guide arm assembly should return toward the drum
assembly and the mechanism should enter the C-IN mode.
As the tape is left without winding, be careful not to damage
the tape or leave grease on it.

(3) If the tape is slack, wind it up by turning the shaft on the top-
side of the capstan motor in the direction of the arrow using
a pointed tool (chip IC replacement jig).This operation may
be difficult because the shaft is located below the housing
motor of the cassette housing assembly. Be careful not to
damage parts during it.
(4) After confirming that the tape is fully wound up, take out the
cassette tape by turning the gear of the cassette housing
assembly in the direction of the arrow.
Note :
• After ejecting the tape, check that grease or similar foreign
material is not attached to the wound tape. Also perform sim-
ilar checking for the mechanism assembly, particularly the
tape transport system.
