WARNINGS AND RECOMMENDATIONS
Warning: Do not plug in the power supply until the outside antenna cable is attached to the
amplier.
Warning: RF Safety: The U-Booster™ cradle/amplier 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 amplier.
Warning: RF Safety: The “outside antenna” requires at least an 8 inch separation distance from
all persons. Other outside antennas may be used provided that (a) they are not within
a building, structure, or vehicle (b) they are located with at least a 30 inch separation
distance from all persons, (c) their gain less cable loss does not exceed 15 dBi, and (d)
they are not operating in conjunction with any other antenna or amplier.
Separation of U-Booster™ and outside antennas is very important. In a vehicle,
the metal roof acts as a barrier and helps shield the two antennas from each other,
preventing oscillation.
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 amplier from oscillating.

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: Amber 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.
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 amber, 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 amber, call ZSVDQWHQQDV Technical Support at.
