Theft-Deterrent Feature
THEFTLOCK ® is designed to discourage theft of
your vehicle’s radio. The feature works
automatically by learning a portion of the Vehicle

moved to a different vehicle, it does not operate
and LOCKED displays.
When the radio and vehicle are turned off, the
blinking red light indicates that THEFTLOCK
®
is armed.
With THEFTLOCK ® activated, the radio does not
operate if stolen.
