1. * This fault indicates mistuning of the PA. It works for Input power higher than 10W. If
output power decreases more than 3dB below value corresponding with the applied Input
power, f ault m essage „ Low o utput p ower" a ppears. Y ou h ave t o t une t he P A c orrectly.
2. *** When the heating voltage exceeds boundaries 9V +/-­‐ 2V, warning message „Heating
voltage error" appears. Check proper position of AC selector (page 25). Heating voltage
without R F s ignal s hould b e b etween 8 .5 a nd 9 V.

4. ***** If temperature sensor inside the PA detects of 80 deg. Celsius, warning message
„Amplifier is too hot" appears on the display. At 90 degrees protection circuit will
automatically block transmitting (fault condition). You have to decrease the power or wait
couple of minutes to be ready transmitting again. Fault is signed with the letter „F" in the
memory.
