Use LCD Display Method to find the location with the strongest received signal
Connect the outdoor antenna to the booster’s outdoor port. Fix the outdoor
antenna on the roof of the building and point it to the nearest cell tower. Then
have a look at gain and output power value displayed on the amplifier’s LCD.
The outdoor antenna receives the strongest signal when the booster’s downlink
output power reaches its highest level in each band.
The booster’s LCD display shows the gain and output power. The output power
can be checked below
“Power (dBm)”
on the LCD display.
NOTE: When the ALC legend is flashing, it means the received signal power is
stronger than the system needs it to be. It is recommended to adjust the outdoor
antenna orientation untilthe ALC alarm disappears. Or you can leave it as it is to
let the booster self-adjust automatically. However, when the ALC flashes, and the
displayed gain is 30dB less than the amplifier’s rated max gain value, try to adjust
the outdoor antenna to decrease the received signal power from the local tower.
Otherwise it may be necessary to install an attenuator on the outdoor antenna
port to decrease the input signal level from the local tower.
• ISO LED
flashing means that ISO function is working well and self-
oscillation has been eliminated. ISO LED will remain “Green” or will be
“Slow Flashing Green”.
Note: This improvement won’t increase the coverage, but is mandatory to avoid
causing interference to carrier’s local cell site towers.
