For in-vehicle, fi rst connect the power 
cable to the amplifi er input marked 
“DC 12 V IN” and then insert the large 
end into a 12 V DC power socket or 
cigarette lighter outlet.

The amplifi er may remain on all the 
time; however, leaving the amplifi er on 
in a vehicle when it is not running can 
discharge the battery in a day or two.

A good option is to power the amplifi er 
through the ignition switch so that 
the amplifi er turns off and on with the 
vehicle.

For in-building, fi rst connect the 
optional AC/DC power supply to the 
amplifi er input labeled “DC 12 V IN” 
and then into a wall outlet.

Carefully insert the power cable.

In-vehicle 12-volt DC power cable (included)

Warning: Use only a Wilson power 

cable.  Use of a non-Wilson product could 
damage your equipment.

NOTE: The aluminum casing of a Wilson amplifi er will adjust very quickly to the 
ambient temperature of its environment. For example, in the summer, when the 
inside of a car can reach 140 degrees Fahrenheit, the amplifi er temperature may 
be 150 degrees or higher. The casing will be hot to the touch, similar to a metal 
door handle or a steering wheel. Such high temperatures will not damage the 
amplifi er, nor do they pose a fi re risk to the vehicle. As recommended in these 
instructions, install the amplifi er in a location with adequate ventilation, such as 
under the seat, in the trunk or under the dashboard.  Keep the area free of items 
that could block air fl ow to the amplifi er.

Warning: Verify that both the outside 

antenna and the adapter extension cable are 
connected to the amplifi er before powering up 
the amplifi er.

In-building AC/DC power supply (optional)
