• The battery polarity markings on the bottom of the
battery compartment must be adhered to.
• Batteries must be installed in the sequence shown.
If batteries seem difficult to install, they're not being
installed in the proper sequence.
• Smoke/CO Alarm will not engage to bracket unless
all three batteries are installed. Removal of any or
all batteries will render the Smoke/CO Alarm
inoperative!
• After the batteries are correctly installed the unit
will beep once and the red LED light will flash.

indicating the unit is now operational.
