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:

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 prepara-
tions 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 con-
tinuously, and the cassette tape will be ejected. Allow
a minute or two to complete this task.
