WARNINGS AND RECOMMENDATIONS
Warning: Do not plug in the power supply until the outside antenna cable is attached to the
amplifier.
Warning: RF Safety: The U-Booster™cradle/amplifier must be installed with a separation of at
least 8 inches from all persons and must not be located in conjunction with any other
antenna or amplifier.
Warning: RF Safety: The FCC requires that a cell phone with cradle attached may only be used
with the cradle mounted as illustrated in this installation guide. A cell phone held near the
ear must be without the cradle attached.
Warning: RF Safety: The OutsideAntennas authorized for use with this amplifier are shown
on page 1 of this guide. Other antennas may be used, but only in fixed installations
when located outside of a building or structure (not in mobile/ portable installations),
provided that:
(a) antenna location ensures at least a 30 inch separation distance from all persons,
(b) antenna gain less cable loss does not exceed 15 dBi, and
(c) such antennas are not operating in conjunction with any other antennas, or
transmitting devices.
If the vehicle has a sunroof, it is important to keep the outside antenna at least 8 inches from the edge of
the sunroof. This prevents the amplifier from oscillating.
Separation of the U-Booster and the outside antenna is
very important. In a vehicle, the metal
roof acts as a barrier and helps shield
the two antennas from each pother,
preventing oscillation.

Troubleshooting
SYMPTOM: Green Light always OFF
1) Make sure that the power source is supplying power to the U-Booster by checking
that the light is on.
2) If the DC plug-in power supply is properly inserted, but the plug’s light doesn’t
come on, then check the 12 volts from the car socket, and check the fuse in the
DC plug-in power supply.
SYMPTOM: Red Light always ON
1) Make sure that the antenna connector is tight.
2) Place the outside antenna on its side (see picture). Reset U-Booster™ power
(off and back on) again. The light should now be green (antenna was too close).
Turn U-Booster™ off and proceed to step 3.
3) Return the outside antenna to its upright position, and move it further towards
the rear of the vehicle, (away from the U-Booster™) but no closer than 8 inches from a sunroof, rear or side
windows. Power U-Booster™ back on and recheck for a green light. If light is still red, continue moving the
antenna further back and resetting the power until the light changes to green and stays green. Remember to stay
more than 8 inches away from a sunroof, rear or side windows.
4) If the light remains red, call Wilson Technical Support at 866-294-1660.
