Welcome to the world of Silencer automotive security. Silencer products have been designed to provide the consumer with a product that is technologically superior, providing years of trouble free operation. This manual will
provide reference for the operation and maintenance of your new Silencer vehicle immobilizer system. This system
is an automatic device that will become armed every time you leave your vehicle. Once armed, the Silencer vehicle
immobilizer will prevent your vehicle's engine from operating, aiding in the prevention of vehicle theft. Take a
moment to read this manual so you will be familiar with the operation of your new system.
Passive Arming
Once you have turned the ignition key to the “Off” position, your Silencer engine immobilizer will become armed
within 30 seconds. Upon arming, the device will emit 1 soft chirp. Turning the ignition back on before 30 seconds
will stop the timer and reset it.
Note 1: This passive arming feature could qualify in some states for an insurance discount. Check with your insurance carrier.
Note 2: If your system was supplied with a “Passive Disarm Transmitter”, you have to leave the vicinity of your
vehicle (approx. 60 feet) before the passive arming function will execute. Remaining in close proximity of your
vehicle will prevent it from arming. This distance requirement may prevent you from hearing the soft arming chirp.

Each time the system is disarmed using the transmitter, the device will begin a protection mode countdown.
This is a timed secondary protection mode to insure the RF signal that disarmed the system came from your
transmitter. If you do not start your vehicle within the 60 second timer countdown, your Silencer system will
become rearmed and your engine will be disabled.
Note: If your system operates from a “Passive Disarm Transmitter”, the 60 second RF protection timer will
not time out and re-arm your system if you remain within 60 feet of your vehicle.
