Radio/Audio System
THEFT DETERRENT FEATUREThe U1C, US8, and US9 are equipped with a programmable theft deterrent feature. When the radio has the SEC (armed) mode activated, the radio will enter the LOCK (locked) mode if the power between the battery and the radio is interrupted for more than 20 seconds. While in the locked mode, "LOCK" appears on the radio display and all radio functions are disabled.
When the vehicle is first purchased or the radio is new or remanufactured, the theft deterrent feature is unarmed. If desired, the customer must program a 4-digit code into the radio to activate the theft deterrent feature.
Operating modes
The theft deterrent feature causes 3 operating modes:
- VULNERABLE (UNARMED) MODE -The radio does not have a 4-digit code stored. If stolen, the radio will operate normally when power is applied.
- SECURE (ARMED) MODE - The radio has a 4-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) mode.
IMPORTANT: Before performing service on a vehicle, verify the theft deterrent feature is in the VULNERABLE (unarmed) mode. This check is made by the following steps:
1. Turn the ignition ON. Radio OFF.
2. Press and hold preset buttons "1'" and "2" for 5 seconds.
3. If SEC (armed), a 4-digit number will appear on the radio display. This number is NOT the customer's code. Ask the 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.
4. If no number appears, the theft deterrent feature is VULNERABLE (unarmed) and service may be performed.
