AIR CONDITIONING AND AUDIO (b) Cancelling the anti-theft system Once the system is set, the indicator light turns on and off with the ignition switch in "OFF" and "SEC" will appear each time the key is turned to the "ACC" position. To change the identification number for some reason, cancel the system (See "(b) Cancelling the anti-theft system.") and set it again with a new number. The system will be activated if the electrical power source is disconnected from the radio unit. When the system is activated, the audio system cannot be turned on even after the power supply resumes and "SEC" will appear on the display. If this happens, such as when the battery is discharged, see "(c) If the anti-theft system is activated." 1. Follow steps 1 to 4 described in "(a) Setting the anti-theft system." 2. With your identification number appearing on the display, press the (SCAN) button and hold it in until "---" appears on the display. "---" will go off to indicate the system is cancelled. If invalid buttons have been used, "Err" will appear on the display and "SEC" appears. Try again from step 3 in "(a) Setting the anti-theft system." The number displayed with "Err" indicates how many errors you have made. You may make up to nine errors, but no more! 127
