Blinking Red: If one or more of the lights
on the Signal Booster are blinking red,
this means that the Signal Booster has
shutoff due to close proximity to the mobile
device. Increase the distance between the
mobile device and the Inside Antenna until
the light is no longer ashing red. Contact
Wilson Electronics Technical Support Team
for assistance.
Green light: A green light indicates the
MobileMaxx 3G Signal Booster is working
properly.
If you have additional questions about
the operation of your MobileMaxx 3G
Signal Booster, please contact the Wilson

How does weather affect the performance of
my outside antenna?
Water vapor (e.g. rain, fog, snow or other
precipitation) creates an effective lter to cellular
signal. In times of heavy precipitation, you may
see less performance.
What’s the difference between the 800 MHz
and the 1900 MHz bands? How do I know
which MHz band my cell phone uses?
The MobileMaxx 3G works with all major North
American cellular providers on the 800 & 1900
MHz frequencies. Traditionally, 800/1900MHz are
associated with voice and 3G data; while 700MHz
and 1700/2100MHz are associated with 4G data.
may be as hot as 150 degrees inside your
vehicle. These high temperatures will
NOT damage the Signal Booster, nor do
they pose a re 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 lights on the top of the Signal Booster
indicate whether the system is working
or if there are problems. The light on the
left is the power light. The other two lights
indicate the operation of 800 MHz and
1900 MHz signals, respectively. Take the
following steps based on the indicator light
color when using the Signal Booster.
Lights off: If the lights are not on:
• Check connections on the power
supply to see that it is rmly plugged
into both the Signal Booster and the
power source.
• 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.
Red light: A red light indicates oscillation is
occurring. Oscillation is similar to feedback
between a microphone and speaker. When
oscillation occurs, the Signal Booster will
power down to protect the cell tower. To
eliminate oscillation, the Outside Antenna
needs to be moved farther from the Inside
Antenna. Move the Outside Antenna on the
roof to the rear of the car, but at least 8 to
12 inches from the rear or side windows.
Disconnect the power from the Signal
Booster, then reconnect the power to reset
the Signal Booster.
