manual radio set GMC SIERRA DENALI 2003 Owners Manual

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 be displayed.
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.
