CM2500W Amplifier - Installation Manual

5.6 - Automatic Shutdown

If equipped, the CM2500W amplifier includes an

automatic shutdown feature that works in the fol-

lowing sequence:

1. When oscillation is detected in the uplink and/

or downlink, the Warning light will begin

flashing red and the Power light will turn red.

2. If the problem is not resolved, the amplifier

will shut down after 30 seconds.

3. The amplifier will wake back up. When this

occurs, the Power light will be green. If oscilla-

tion resumes, the lights will flash as previously

described. These 30-second cycles will con-

tinue for 15 minutes or until the problem is

resolved.

4. If the problem is not resolved within 15 min-

utes, the amplifier will shut down (all lights off

except the Power light, which is red) and must

be reset by unplugging it from the power sup-

ply and plugging it back in.

To resolve oscillation, increase the antenna sepa-

ration (Section 3.4) and/or the attenuation (Sec-

tion 5.1).
