adjust the gain by DIP switch, firstly please
adjust Downlink gain according to input
signals, secondly please adjust Uplink gain
according to Downlink gain.
The DIP Switches have default ‘OFF’ status;
please push relevant switches to “ON”
position if certain attenuation value needs to
be achieved.
