INVALID FREQ
1KW amplifier could not determine
the operating frequency.
The frequency is measured by
automatically causing the
RM125/RM125R to transmit a low
level (about 5W) pilot tone for a few
seconds after each frequency change,
and also whenever the ENT key of the
RM125/RM125R is pressed
Check the cable connections
between the RM125/RM125R and
the 1KW amplifier.
Repeat the frequency measurement
process by pressing the ENT key of
the RM125/RM125R and monitor
the RM125/RM125R display: it
should switch to the transmit mode
for a few seconds, and its transmit
display should include at least two
bars
