Repeater Settings
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.
