Compact Disc Messages
If an error occurs while trying to play a CD in the
compact disc player or changer, the following conditions
may have caused the error:
D
The road is too rough. The disc should play when
the road is smoother.
D
The disc is dirty, scratched, wet or loaded label
side up.
D
The air is very humid. If so, wait about an hour
and try again.
D
The CD changer door is open. Completely close
the changer door to restore normal operation.
D
An empty magazine is in the CD changer.
Try the magazine again with a disc loaded on
one of the trays.
D
If the CD is not playing correctly, for any other
reason, try a known good CD.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer. If your radio displays
an error message, write it down and provide it to your
dealer when reporting the problem.
Theft-Deterrent Feature
THEFTLOCK R is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power has been interrupted. If your battery loses power
for any reason, you must unlock the radio with the secret
code before it will operate.

Activating the Theft Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.
