7.3. Repeater Settings
7.3.1. Indicator Light Instructions
• The equipment works correctly when power LED indicator light P is on, any other status means power failure
or equipment failure.
• The equipment works correctly when both Up-link indicator light U and down-link indicator light D are on.
The up-link incoming signal is very strong and the equipment output is large when the light U is flashing
slowly. The down-link incoming signal is very strong and the output of the equipment is large when the light
D is flashing slowly.
• Either indicator light U or D is off in case the up-link or down-link breaks down. The equipment experiences
self-excitation when both U and D lights are flashing quickly.
Troubleshooting
• When the ALM light is flicking or on, and the booster has self-oscillation issue, it indicates the wrong
installation of indoor and outdoor antenna. In this case, please, read antenna installation instructions again
and re-install the antennas.
• When the ALM light is flicking or on, and the input signal is too strong, please, change the direction or place
of your outdoor antenna.
