LED Indicators
Place a call in a location you have previously experienced poor signal and confirm that your phone is receiving a boosted signal.
Normal operation is indicated by Green LED’s (both flashing and solid). In the event Red LED’s appear, antenna adjustments may
be needed.
Color Condition Indication
Green Solid Indicates normal operation.
Green Flashing
Normal operation. Indicates that Automatic Gain Control (AGC) is self adjusting due to over-signal
or antenna proximity.
Red Flashing
Indicates issues caused by overpowering or oscillation. Adjustment of your outside antenna
placement is likely needed. Verify that it has sufficient separation from the inside antenna, as well
as, any potentially interfering objects or antennas
Note that the booster case may become warm during operation. This is normal.

signal has not Improved
Verify that all cable connections are tightly fitted to the booster. Try further separating the
antennas. i Note: Bars are not always a reliable measure of signal. The best way to
confirm signal coverage is the ability to place and hold a call.
