SERVICE BULLETINS

If the unit continuously goes into Demo mode after

setting it for Home use, verify front touch sensor
operation. If any or all of the buttons do not
respond, make sure 5v is present from the main
board. If so, replace the touch sensor. The touch
sensor in these models is difficult to access due to
the plastic reinforcement along the bottom of the
front cover, so the entire front cover may have to be
replaced.
