Cassette Tape Messages
CHK TAPE (Check Tape): If CHK TAPE appears on
the radio display, the tape won't play because of one of
the following errors.
The tape is tight and the player can't 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, your
tape may be damaged and should not be used in
the player. Try a new tape to make sure your 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: If this message appears on the display, the
cassette tape player needs to be cleaned.
It
will still play
tapes, but you should clean it as soon as possible to
prevent damage to the tapes and player. See Care
of Your Cassette Tape Player on page 3-74.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer.
CD Adapter Kits
It is possible to use a portable CD player adapter kit
with your cassette tape player after activating the bypass
feature on your tape player.
To activate the bypass feature, perform the following
steps:
1. Turn the ignition on.
2. Turn the radio off.
3. Press and hold the TAPE DISC button for five
seconds. The radio will display READY and the
tape symbol on the display will flash, indicating the
feature is active.
4. Insert the adapter into the cassette tape
slot. It
will
power up the radio and begin playing.
The override feature will remain active until the eject
symbol is pressed.
