The manual, which you can download for free from SRS, says (page 57):

"If the UHF prescaler of channel A is selected when
the unit is powered off and then on again, the unit
will display “TEST ERROR 34”. This error may be
corrected by deselecting the UHF of channel A. To
run this procedure, press input button of channel
“A” until UHF is not highlighted. Then turn the
power off and on again."

So RTFM and execute accordingly might be all that you need to do.
