Service Information
A. Method for Manual Tape Loading/Unloading
To load a cassette tape manually:
1. Disconnect the AC plug.
2. Remove the Top Case and Front Assembly.
3. Insert a cassette tape. Though the tape will not be
automatically loaded, make sure that the cassette
tape is all the way in at the inlet of the Cassette
Holder. To confirm this, lightly push the cassette
tape further in and see if the tape comes back out,
by a spring motion, just as much as you have
pushed in.
4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 for a minute or two to complete
this task.
To unload a cassette tape manually:
1. Disconnect the AC plug.
2. Remove the Top Case and Front Assembly.
3. Make sure that the Moving guide preparations are
in the Eject Position.
4. Turn the LDG Belt in the appropriate direction
shown in Fig. M1 until the Moving guide
preparations come to the Eject Position. Stop
turning when the preparations begin clicking or
can not be moved further. However, the tape will
be left wound around the cylinder.
5. Turn the LDG Belt in the appropriate direction
continuously, and the cassette tape will be
ejected. Allow a minute or two to complete this
task.

loaded position without a cassette tape
1. Disconnect the AC Plug.
