CAUTION: When the unit is powered the first time, a rechargeable

display back up battery begins charging. When fully charged it
provides approximately 200 hours of reserve time before the display
and program may be lost. If the unit loses power, it will not lose the
program for 200 hours, but it will not run the pump from the
rechargeable display back up battery and will not dispense chemical. If
the unit becomes unplugged from the wall for a short amount of time,
plugging the unit back in will not affect the programming done to the
unit.
