If it shines “orange”, use 1dB as stepping to increase attenuator until “green”
turns on, then decrease 1~3dB attenuation value until “orange” turns on. The
setting of downlink gain can reach the perfect status.

If it shines “green” then,
◆
To check whether the attenuation value has been set, if it is, use 1dB as
stepping to decrease attenuation until the “orange” turns on, then the downlink gain
can reach the perfect status.
◆
But if attenuation is not set, it indicates that the input power is not enough.
Then please check coverage effect first, if the coverage effect is good, the
engineering has reached expecting target
But if the coverage effect is not so good, the donor antenna should be adjusted until “orange”
turns on or the effect reaches the target.
Uplink gain setting
Uplink gain is set based on downlink gain..
Standards: uplink attenuation value=downlink attenuation value
