This indicates excessive input power from the Transceiver on
the bands from 80 to 10m. The amplifier will sound 5 short error
tones and the Alarm LED

b

will illuminate. Reduce the input

power and press the STB/OPR key

d

to reset the amplifier.

This indicates excessive input power from the Transceiver on
the bands 160 and 6m. The amplifier will sound 5 short error
tones and the Alarm LED

b

will illuminate. Reduce the input

power and press the STB/OPR

d

key to reset the amplifier.

This indicates that the transmission frequency is outside of the
predefined limits, (1.5-54MHz). The FCC version is also band
blocked, (26MHz –27.9 MHz). 5 short error tones will be
emitted and the Alarm LED

b

will be illuminate. Change the

transmission frequency, press the STB/OPR

d

button to reset

the amplifier.

This indicates that the current antenna SWR is above 2.5:1 and
the amplifier will return to Standby. The amplifier will emit 5
short error tones the Alarm LED

b

will illuminate. To clear

the error check and adjust the antenna SWR then press the STB/
OPR

d

button to reset the amplifier.

This indicates excessive Drain Current. The amplifier will emit 5
short error tones and the Alarm LED

b

will illuminate. Check

that the amplifier is not being over driven and that the antenna
SWR is within acceptable limits <2.0:1. Then press the STB/
OPR

d

button to reset the amplifier.

This indicates that the drain voltage is above 70V. 5 short error
tones will be emitted and the Alarm LED

b

will illuminate.

Check that the AC input voltage is correct. To reset the amplifier
press the STB/OPR

d

button.

This indicates that the drain voltage is below 40V. 5 short error
tones will be emitted and the Alarm LED

b

will illuminate.

Check that the AC input voltage is correct. To reset the amplifier
press the STB/OPR

d

button.

This error indicates a problem with the PIN Diode RTX
switching. 5 short error tones will be emitted along with the
Alarm LED

b

being illuminated. This creates a non recoverable

error and the amplifier will need to be switched off and on again.
If this problem continues you will need to contact technical
support.
