Theft-Deterrent Feature
THEFTLOCK ® is designed to discourage theft of your
radio. The feature works automatically by learning a
portion of the Vehicle Identification Number (VIN). If the
radio is moved to a different vehicle, it will not operate
and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
® is armed.
With THEFTLOCK ® activated, your radio will not operate
if stolen.
