Theft-Deterrent Feature
THEFTLOCK@ is 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@ 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.
