ClrALM: This is the Clear Alarm screen which is used to clear all alarms.
In LOCAL MODE, press the ClrALM button and a window pops out as below.
Press Yes to clear all the alarms and restore the rated power. Alarms will not clear
if they are currently active.
System:
The System screen is used to run Optitune (AUTO_G_P) and One-Button
Adjusting PSU output voltage.
In LOCAL MODE, press the V_Down button to One-Button reducing all PSUs’
output DC voltage to 46VDC. If the transmitter is running at reducing power, reducing
PSU output voltage will help improving system efficiency while performance still
guaranteed.
Likewise, press the V_Resume button to One-Button bringing all PSUs’ output
DC voltage back to the regular 50VDC.
Press AUTO_G_P to run automatic, adaptive phase/gain matching between all PA
modules in the system. It takes about 3 minutes to complete.
