coverage.

"Power dBm"– Power Indication.

The displayed value shows real-time downlink power that the amplifier is delivering

to the indoor antenna port. When the amplifier DL output power is lower than

-10dBm, the value will display "---".

"ISO" – Isolation Alarm Indication.

When the system does not have enough isolation between the outdoor and indoor

antennas, the "ISO" indicators will be flashing showing that the ISO is lowering the

gain in some bands to keep the system from oscillating. Press the "SET" key and the

LCD screen will display "ISO" showing the current band or bands affected.

"ALC" Flashing.

When the amplifier is receiving too much DL power from the tower and the DL

amplifier output is close to saturating, the "ALC" indicators will flash showing that

the ALC has lowered the gain to prevent this overload condition. Press the "SET"

button and the screen will show the band or bands affected.

"OFF"- Booster shut-off alarm indication.

In some rare situations the ALC or ISO will not be able to compensate for an

oscillation condition or a downlink overload. When this happens the amplifier

will shut off in the affected band and the LCD "OFF" indicator will flash. Pressing

the "SET" button will display which band or bands are affected.
