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 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, the radio will not operate
if stolen.
