TROUBLESHOOTING
Eliminate Flashing ISO legend and Quick Flashing Green, Quick Flashing Red ISO
LED problems:
1. Adjust the outdoor antenna direction, keeping it away from the indoor
antenna. Restart booster.
2. Increase the vertical or horizontal distance between the outdoor antenna and
indoor antenna. Restart booster.
3. Use barriers such as walls to increase the isolation.
4. Change the indoor antenna type to an antenna with a more directional
antenna pattern. Orient the indoor antenna and outdoor antenna so they
point in opposite directions.
5. Reduce the booster's downlink gain using the manual gain controls. Keep
the uplink gain value and downlink gain value the same then restart the
booster.
Note: Uplink gain must be equal to or not less than 5dB below the downlink gain
to avoid interference with the local carrier's cell site network.
Target: The ISO issues are solved when the ISO LED is "Green" or "Slow Flashing
Green" or no flashing ISO legend.
Eliminate Flashing ALC legend and Quick Flashing Green, Quick Flashing Red Alarm
LED problems:
1. Adjust the antennas' directions or locations to lower downlink received signal
level.
2. Slowly reduce the downlink gain using the Manual Gain Controls.
3. If the above methods don't work, reduce the booster's gain with an external
attenuator in line with the outdoor antenna or replace with lower gain
antenna.
Target: The overload issues are fixed when the Alarm LED is "Green" or "Slow
Flashing Green" or no flashing ALC legend. Please note that a "Green" LED
indication may result in smaller coverage area. This can be improved by
adjusting the outdoor antenna to receive a stronger signal.
Eliminate poor coverage problems when Power
legend on LCD and Alarm LED
is Green:
1. If the signal has not been improved, please check below:
- The weak downlink signal leads to the low output signal level. Change the
direction or position of the outdoor antenna. You may also try replacing the
outdoor antenna with a higher gain antenna to increase the incoming signal.
- Check to see if it is necessary to add more indoor antennas. Barriers such as
walls can block the signal indoors. You should also check the booster to make
sure the power is maximized. Try installing more indoor antennas or replace
the booster with a higher powered one.
2. If the signal in a small section of the building hasn't been improved, try the
