Operating Modes

The theft deterrent feature causes three operating modes:
^ VULNERABLE (UNARMED) MODE - The radio does not have a four-digit code stored. If stolen, the radio will operate normally when power is supplied.
^ SECURE (ARMED) MODE - The radio has a four digit code stored. The radio will enter the LOCK (locked) mode if the power between the battery and the radio is interrupted for more than 20 seconds.
^ LOCK (LOCKED) MODE - The radio has been removed from power for more than 20 seconds or the wrong four-digit code has been entered while in the SEC (armed) more.

IMPORTANT: Before performing service on a vehicle, verify the theft deterrent feature is in the VULNERABLE (unarmed) mode. This check is made by performing the following steps:

^ Turn ignition On. Radio Off.
^ Press and hold preset buttons "1" and "2" for five seconds.
^ If SEC (armed), a four digit number will appear on the radio display. This number is NOT the customer's code. Ask customer to disarm the feature by following the procedure given in the owner's manual. The procedure is the same procedure used for activating the theft deterrent feature.
^ If no number appears, the theft deterrent feature is VULNERABLE (unarmed) and service may be performed.
