Keyless Entry Transmitter: Description and Operation

In addition to the LOCK and UNLOCK buttons on the transmitter, there is another button which is used to activate the siren if a threatening situation occurs while the driver is approaching the vehicle. If the panic button is held down for 2 seconds, the siren will be activated for 30 seconds. The turn/hazard lamps will flash during that time.
