GENERAL TROUBLESHOOTING
fault description
Unable to turn on your PA500
Antenna tuning function does
not work / tuner does not tune
No transmission / no
amplification
When the PA500 current draw is too high (more than 15A), or a short circuit occurs, the
internal fuse may blow. The unit will then no longer turn on. The device needs a service.
Do not allow the maximum output power of the amplifier to exceed 40 W.
The PA switches to bypass mode when the maximum output power is exceeded by 1 dBm
Using the PA500 at high power levels for extended periods can lead to overheating and
potential damage to the PA stage.
