ADJUSTING MANUAL GAIN CONTROL
The Manual Gain Control is used to resolve the issue of oscillation without the need of readjusting your
antennas, in most cases. The manual gain control (MGC) adjusts the overall amplication level (gain) of the
booster.
The MGC allows you to easily reduce the amount of gain (amplication) the booster is emitting. This is done
with a set of dip switches on the side of the booster. There is a series of dip switches to adjust the uplink and
another set to adjust the downlink.
There are 2 sets of dip switches, one is labeLED “high frequency” representing the 1900 mhz range and the
other labeled “low frequency” representing the 850 mhz range. Each set is divided between the downlink
and the uplink. The dip switches, when put into the “on” position will reduce the gain of the booster for the
designated frequency and transmission direction. When the LED alarms are indicating some oscillation you
need to reduce the gain of the downlink and the uplink for the appropriate frequency. Do this gradually in
order to determine the ideal level.
ADJUSTING THE UPLINK
Please follow these procedures for each frequency.
If the alarm LED turns off immediately after commissioning the system, the signal on the uplink is likely too
strong. Take measure to reduce the uplink gain. Continue to increase the gain reduction until the alarm light
changes to green.
ADJUSTING THE DOWNLINK
Once you have ne-tuned the uplink signal, it is time to adjust the downlink. If the alarm LED is green you are
all set. If the alarm LED is orange, you will only need to reduce the gain slightly. If the alarm LED is red, you
will need to greatly reduce the gain. As you implement the gain reductions, the LED alarms should change
from Red or Orange to green.
