See tables on next page for detailed decoding of faults.
The two Status screens may be used with the LED indicators on the PA module and the System Controller
module to locate a fault.
Note: The FWD and REV power readings on T-4180 Status screen #1 indicate the power measured
at the output connector of the Combiner. The power reading is for reference only and may
not match the reading of an external wattmeter - especially when operating into high VSWR
conditions.
The VSWR indicates the VSWR measured at the output connector of the Combiner. The
VSWR reading is for reference only and may not match the reading of an external wattmeter.
