I have never Encountered that one on a Pioneer 10G.. usually when it sneezes I do just like Marty said.
unplug it for 60 seconds and plug it back in.
Or read your owner's manual...
I don't use the "repeat" mode on the 10G. Actually I never looked at it close enough to know it had one.. I have only used them 3 in shows as "loaners".
Gimme A JVC/RSQ Machine or Pioneer's V-888 or Gimme DEATH!!!
