Theft Deterrent Feature
The radio has this feature it shows THEFTLOCK on its face. THEFTLOCK®
is designed to discourage theft of the radio. It works by using a secret code
to disable all radio functions whenever battery power is removed.
If THEFTLOCK® is active, the THEFTLOCK® indicator will flash
when the ignition if OFF.
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, the radio will not operate if stolen.
When THEFTLOCK® is activated, the radio will display LOC to indicate
a locked condition anytime the battery power is removed. If the battery loses
power for any reason, you must unlock the radio with the secret code before
it will operate.
