DORAN Exterior Signal Booster
Installation Instructions
The Doran Exterior Signal Booster, part #3625, was developed to assist in getting hard to read sensor
signals to the Doran Tire Pressure Monitor. To accomplish this, the Booster is designed with a receiver and
a transmitter for the sensor RF signals. This Booster is built with heavy-duty weatherproof construction so
it can be used outside of the vehicle.
1. Supplying Power to the Exterior Signal Booster
The Booster will need to be powered by a 12-volt
negative ground system. When connecting the Booster
to the electric supply, you will need to connect the RED
wire to a 12-volt positive (+) source and the BLACK wire
to a negative (-) source. The Booster is fused internally so
additional fusing is not necessary.
When connected to the power, there is an LED light
visible through the cover plate, located where the power
cord enters the unit. The light will remain on whenever
the unit is powered.
2. Placement of the Exterior Signal Booster
It is best to locate the Booster towards the rear of the
vehicle so the sensors located farthest away from the
monitor can communicate with the monitor.
Try to keep the Booster from being surrounded by metal,
as this can greatly reduce its effectiveness.
The best reception of the and signal transmission will be
achieved from mounting the Booster behind the rear
axle of the vehicle. We suggest you test the location of
the Booster, and the reception and transmission of RF
signals before you permanently attach it to the vehicle.
3. Mounting the Exterior Signal Booster
It is best to mount the Booster in a vertical position,
towards the rear of the vehicle.
It will also work attached in other positions, but the full
potential may not be realized.
Mount the Booster using the 4 mounting tabs and the
bracket included in the kit.
