Theft-Deterrent Feature
THEFTLOCKžis designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is interrupted.
The THEFTLOCK
žfeature 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
žis
activated, your radio will not operate if stolen.
When THEFTLOCK
žis 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.
