I have cured the heater problem but don't know how to reset the u4 code.........any ideas?
turn on power while holding down "0", press "stop/clear" and wait 30 seconds for optics to finish initializing, then enter "401" then "print", shut off machine, wait 10 seconds and turn back on. code should now be cleared.
hth,
