Step 3: Connect To Power
Plug the DC Power Adapter into the power port of your car, plug the power cable into
the phone mount antenna and switch power to ON. You will see a red light on the power
adapter and a green light on the phone mount antenna when the system is powered ON and
boosting cellular signals.
Only the phone on the phone mount antenna will receive the improved cellular signal.
Note: Power the signal booster switch to OFF when car is not running to keep the booster
from drawing from the car’s battery.
* WARNING: The booster is rated for 5-15V input voltage. DO NOT use the booster with a higher voltage power
supply. This can damage the booster and/or cause personal injury.
