TROUBLESHOOTING

The LED alarm lights represent the status of the booster on each frequency.
When the lights are green the device is operating normally meaning that it is not
experiencing any oscillation (feedback) and it is boosting the signal at maximum
power. When the LED lights begin to change color from green to orange to red, it
means that particular frequency is experiencing some oscillation (feedback).
If the oscillation is excessive the booster will shut down for that particular frequency.
The booster will still work for the other frequency on a multi-band booster.
Oscillation is caused when the indoor (distribution) antenna sends a signal back into
the outdoor (signal) antenna. Similar to a PA system, when the microphone gets
too close to the speaker it causes feedback. This will occur if your antennas are too
close together, or the indoor antenna is pointed at the outdoor antenna. Make sure
you have adequate separation and some type of shielding between the antennas
(usually your roof or a cement wall is good enough).
IMPORTANT NOTES
The 2 most important things to look for when setting up your system is:
1
A good input signal (the best you can find)
2
Isolating the outdoor (signal) antenna from the indoor
(distribution) antennas so they do not feedback into each other.
