Downlink gain setting
First the alarm LED only indicates the downlink input power level, here we use color of Alarm LED
to adjust the gain of the repeater. Alarm LED color must remain green. As for the downlink
working performance, it is a good working point that Alarm LED maintains “Green” color with the
intention of turning orange; here we refer as “edge point”. At this time, downlink output power and
coverage effect are stable.
And the equipment must be as far as possible away from overloading status of “red”
