PROBLEM DESCRIPTION
POSSIBLE SOLUTIONS
Everything appears normal, but there
is no RF power
1. Wait a few more seconds, amplifier need about 20 seconds to get their power to full
2. Maybe one of the alarms was triggered and power was reduced, try to power off and
power back on, whenever an alarm is triggered power may be reduced until you power
off and back on
RF output power is too low
1. Check the set power (in %)
2. Maybe one of the alarms was triggered and power was reduced, try to power off and
power back on or wait a few minutes for power to recover.
3. Find out which alarm was triggered, maybe your unit is over-heating or your antenna
(SWR) may be way off. Let the unit cool off and ensure proper cooling in the future.
Perhaps you adjusted TEMP ALARM or another alarm too low, set it slightly higher.
4. Exciter or driver may be too weak.
5. Power limit may be set too low (it is shown at power-up time)

TEMP/SWR error warning
1. Unit is probably over-heating or your antenna is faulty. Let the unit cool off and
ensure proper cooling in the future. Perhaps you adjusted TEMP ALARM too low, set
it slightly higher.
2. It is very likely that your antenna is not working correctly, check cable and check
SWR. You may need to adjust SWR ALARM slightly higher (but first make sure your
antenna and cable are OK).
Unit blows fuses and draws excessive
current
You may have burned the output transistor.
