2.

 Run the outside antenna cable
into the car. The cable is strong
enough that it may be shut in most
vehicle doors without damaging the
cable. For a cleaner look, carefully
pull down the door seal, run the
cable under the seal, and push the
seal back into place. This method
reduces wear on the cable as the
door opens and closes.

3.

 Install the Low-Profile inside antenna.

•  Identify a place on the right side

of the driver’s seat to mount the
inside antenna. The location
should be at least 18 inches from
where the cellular device will be
used.

 •  Install the inside antenna at the

same angle as the cell phone
when held in use or near the
laptop’s cellular data card to
maximize signal strength.

 For a more professional look,
you can install the inside antenna
underneath a car seat cover or
upholstery.

•  When you have tested the

functionality of your Drive 4G-M
Signal Booster, mount the inside
antenna by peeling off the backing

of the Velcro

®

 and attach it to your 

selected location on the seat and 
secure the inside antenna.

4.

 Place and connect the Drive 4G-M
Signal Booster.

•  Select a location for the Signal

Booster that is free from excessive
heat, direct sunlight and moisture
and that has proper ventilation.
Good locations include underneath
a seat or under the dashboard.

•  Connect the wire from the outside

antenna to the port labeled
“outside antenna” on the Signal
Booster.

•  Connect the wire from the inside

antenna to the port labeled “inside
antenna” on the Signal Booster.

•  Plug the power adapter into

vehicle’s 12V DC power supply
and attach the cord to the side of
Power Booster labeled “Power.”
NOTE: Do NOT connect the power
to the Signal Booster until you
have connected both the inside
and outside antennas.

•  Power up your Signal Booster by

flipping the switch on the back of the 

DC power adapter on. A red light
should appear on the power adapter.

 Green/red  Blinking

 indicates 

that the booster is operating at a 
reduced gain to prevent oscillation 
(feedback).

Fixing Red Light Issues 

If one or more lights on the Signal Boost 
are red: 

1.

Make sure all connections are tight.

2.

 Increase the distance between the
outside antenna and the Drive 4G-
M, by moving them horizontally and/
or vertically farther apart until the
light(s) change to green. Remember
to keep the antenna at least 6
inches from any window or sunroof.

3.

 Follow the same steps for a green/
red blinking light until the light goes
solid green.

Lights Off 

1.

 Check connections on the power

supply to see that it is firmly plugged

into both the Drive 4G-M and the
power source.

2.

 If using a DC power supply in your
vehicle, ensure the power supply is
properly inserted. Then check the
12 volt power from the car socket
and the fuse. Replace the fuse if
necessary.

3.

 If using a power strip in a building,
ensure the power strip is plugged
in and turned on and that power is
coming from the outlet.

Note:   The Drive 4G-M Signal Booster 

may remain on, in vehicles whose 
12V DC power sources do not 
automatically shutdown when the 
vehicle is turned off. This could 
result in discharging the vehicles 
battery in one to two days. 

Note:   Some 12V DC power sources 

are shut down when the vehicle 
ignition is turned to off. Refer to 
your vehicle owners manual for 

specifics related to your vehicle. 

NOTE: The aluminum casing of 
your Signal Booster will adjust to the 
temperature of its environment, but is 
designed to protect the Signal Booster 
technology. For example, in the summer, 
the Signal Booster case may be as hot 
as 150 degrees inside your vehicle. 
These high temperatures will NOT 
damage the Signal Booster, nor do they 

pose a fire risk to the vehicle. Again, be 

sure to place your Signal Booster in a 
location with adequate ventilation and 
away from direct sunlight or moisture.  

Troubleshooting & 
Understanding Lights  

The Signal Boost includes 4 indicator 
lights on the front of the Drive 4G-M. The 
indicator lights will either be green or red.

 Green

 

indicates that the booster is 

powered and operating at maximum 
gain. 

 Solid  Red

 indicates that the booster 

has shut off on the associated 
frequencies to prevent oscillation 
(feedback).
