Security Lamp/Indicator: Description and Operation

Security Indicator

There is a SECURITY indicator on the instrument panel. After the LOCK button of the transmitter is pressed, the module/receiver is placed in the armed mode, and the SECURITY indicator flashes. The SECURITY indicator turns ON for 0.1 second and OFF for 0.7 second, and it flashes at that frequency until the module/receiver is disarmed.
