SECTION X
OPTIONAL 9 VOLT BATTERY
BACKUP
Dryers ordered from the factory with the 9 volt battery backup option (battery is not included) allow the Phase
5 microprocessor controller (computer) to maintain its operating status should a momentary power interruption
occur while the dryer cycle is in progress.
It is suggested that the battery be replaced at least once a year or as found necessary. The battery life will
depend on the age of the battery, the amount of power interruptions, and the backup time used.
IMPORTANT: For proper operation use alkaline batteries ONLY. Suggest Energizer, Duracell
or equivalent. DO NOT USE CARBON TYPE BATTERIES.
