4.5 Manual Gain Control (MGC)

Since the booster has a very good self-adaptive smart automatic level control (ALC)

and isolation gain processing (ISO) , most of the time manual adjustments are not

required to achieve good coverage. However, in some cases where the ALC or ISO is

working at a very high rate to adjust the gain and the Alarm or ISO LED is flashing

more than once a second a manual adjustment might be desired.

When the LCD is in the fixed display mode, press the "SET" key for more than 3

seconds. It will go into the "Gain Setting Mode" and make one of the gain values start

to blink.

 Press "SET" key shortly, and the LCD will switch to the next gain value and it

will start to blink. (uplink or downlink gain for a different band).

 Press "INC+" key once shortly and the gain will increase by 1dB, Press

"DEC-"once shortly and the gain value will be reduced by 1dB.

 Press the "SET" key for 3 seconds, and the LCD will return to the fixed

display mode.

Note: When adjusting the gain manually, please ensure that the uplink gain

is equal to or not 5 dB less than the downlink gain setting. This avoids

interference with the local cell site tower network.
