BACKUP BATTERY REPLACEMENT
Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.
The smoke alarm uses a 9 Volt battery. The battery should last for at least one year under normal
operating conditions. The smoke alarm has a low battery indicator, an audible "beep." It will operate
at 30-40 second intervals for a minimum of 7 days. When this indication occurs, replace the battery
with an Alkaline type (Eveready Energizer #522, Duracell #MN1604), Carbon-Zinc type (Gold Peak
#1604P, Eveready #216). Use the convenient QUICK DRAW
(R) pull-out batterydrawer for easy battery
replacement.
Pull the QUICK DRAW (R) battery drawer open and remove the battery. While observing polarity,
push the replacement battery into the battery drawer until it is held securely in place. Carefully close
and latch the battery drawer.
REPAIRS AND SERVICES
The smoke alarm contains less than 1 microcurie (37 kilobecquerel) of Americium 241, a radioactive
material. The distribution of these ionization-type smoke alarms is licensed by the U.S. Nuclear
Regulatory Commission; the consumer is exempt from any licensing or requirements. If the
smoke alarm is defective in any way, do not tamper with the unit. Return the unit for servicing. (See
warranty for instructions or in-warranty returns.) There will be a service charge for repairing out of
warranty units.

Before using the alarm "silence" feature, identify the source of smoke and be certain that
safe conditions exist.
(UTHA) MAINTENANCE:
The smoke alarm is virtually maintenance free. However, under dusty conditions, a vacuum hose
may be used to clear the sensing chamber of dust.
Clean the smoke alarm at least once a month to remove dust, dirt or debris. Always turn off power
to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum cleaner,
vacuum all sides and cover of smoke alarm. Be sure all the vents are free of debris.
If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm
should be replaced.
