LED INDICATIONS

Condition

Yellow Solid The frequency band is not in use. Eventually, the band will enter sleep mode. When the light is off, it means
things are normal, and that the band is active.
Yellow Flashing The Automatic Gain Control (AGC) is self-adjusting. This occurs during normal operation.
Red Flashing The booster is receiving too much signal. Can cause the affected band to automatically turn off. If this happens:
1. For kits using an OMNI outside antenna, relocate the outside antenna to a location where the signal is
weaker.
2. For kits using a YAGI outside antenna, turn the antenna in short increments away from the signal source.
3. Increase the separation between antennas (more vertical separation works best).
4. Add an inline attenuator to the cable connected to the Outside port on the booster.
Red Solid The associated frequency band is off. If the red light ashes for a long time (caused by too much signal), and then
turns solid red, it means the associated frequency band has been turned off. This will happen if the gain dial for
that frequency band has been turned all the way down.

Self-oscillation has been prevented. Try this:
1. Increase the separation between the inside and outside antennas. If your booster kit uses two directional
antennas (example: outside Yagi antenna and inside panel antenna), ensure that they are facing away from
each other.
2. If the condition continues, lower the dB gain setting in small increments until the light turns off or ashes
yellow.

5.5 Testing & Troubleshooting
Once the booster is powered on (and no Warning lights are on), walk around the area to assess the voice and/or
data signal in representative variety of locations. Rene the antenna locations and/or gain levels as needed, and then
complete the permanent installation when you are condent the system will perform well.
A few tips and some perspective:
• It’s not realistic to expect full reception everywhere in the building.
• As a general rule, increasing gain by 6 dB doubles the coverage distance of the interior antennas. Start at the lowest
gain and increase gradually as needed.
• If one or more red Warning lights comes on, it indicates there is oscillation in that band and adjustments are
needed.
• If you can’t get the coverage reasonably well-balanced, you may need to install an additional interior antenna and/
or a different type of interior antenna and/or relocate interior antennas.
