Note:

1) FWD-ADJ/REF-ADJ/REJT-ADJ: These are used to calibrate the forward power, reflected power

and rejected power meters. Calibration values may vary by channels. Every amplifier is calibrated

at the channel specified by order in the factory before shipment. If you would like to run the

amplifier at a different channel (within the allowed range of the amplifier) or to calibrate the

readings again for any reason, please contact the manufacturer for technical support. Otherwise,

inaccurate readings caused by the wrong calibration may cause false alarms (if readings are higher

than the actual power level), or lose the ability to protect the amplifier (if readings are lower than

the actual power level) and may cause damage to the amplifier and void the warranty.

2) ATT: This is to set the value of the internal attenuator in the amplifier. The higher the value, the

more it attenuates the input level and therefore the output level. If the default "0" stands for no

attenuation at all, "4" stands for 1dB in attenuation, "8" stands for 2dB in attenuation, and so on.

We recommend keeping the value as default (0). Usually, the ATT value in the Status should

match the ATT setting in System Set Tap when the amplifier is running normally. If not, it is

possible that the amplifier has triggered some alarm and entered the auto-protection mode.

3) RF-RESTART: if an amplifier is in the auto-protection mode, you can set RF-RESTART to ON to

clear all the alarm(s) and restart the amplifier. After RF-RESTART, please check again to see if the

alarm is gone and ATT is back to pre-set value. Sometimes you may need to clear more than once

to bring the amplifier back.

Important: To be safe, before you run RF-RESTART to clear the alarm, please first lower the
