Err
Code
Description Possible Cause Things to Check Correction
388 POST monitor
timed out- did not
respond to a POST
command

Cycle system power and deter-
mine if this error is repeated.
Replace the
Controller assembly.
389 Dial setting over

The front panel power set-
ting exceeds the limit for the
selected mode.
Cycle system power and deter-
mine if this error is repeated.

391 Monitor detected
the wrong RF
waveform
The Monitor has detected
an improper RF Amplifier
drive waveform or frequency
for the selected mode.

sense pins of the ADC when the
system is not activated.
Verify that all cables are properly
connected.
Replace the
Controller assembly.
