Cassette Tape Messages
If an error occurs while trying to play a cassette tape,
it could be for one of the following reasons:
The cassette tape is tight and the cassette player
cannot turn the tape hubs. Remove the tape.
Hold the tape with the open end down and try to
turn the right hub counterclockwise with a
pencil. Turn the tape over and repeat. If the hubs
do not turn easily, the tape may be damaged
and should not be used in the player. Try a new
tape to make sure the player is working properly.
The tape is broken. Try a new tape.
The tape is wrapped around the tape head.
Attempt to get the cassette out. Try a new tape.
CLEAN TAPE:If this message appears on the display,
the cassette tape player needs to be cleaned. It will
still play tapes, but it should be cleaned as soon
as possible to prevent damage to the tapes and player.
SeeCare of the Cassette Tape Player on page 3-105.
If the cassette tape is not playing correctly, for any other
reason, try a known good cassette.
If any error occurs repeatedly or if an error cannot be
corrected, contact your GM dealer. If the radio displays
an error message, write it down and provide it to
your GM dealer when reporting the problem.
