Reset
Should you experience problems with the proper function of your
unit, you may need to reset the unit's computer-controlled electronics.
To do so, take a small pointed object, like the end of a paper clip, and
push RESET located beside the cord inlet on the left rear of the unit.
This will reset all time, calendar, alarm and recorded memo settings to
original factory settings.
