6. Model KN-COEG-3 Operating Characteristics
If the battery is low or missing, or if the unit malfunctions, it will display
other readings (and alarm differently) to alert you of specific conditions.
Please familiarize yourself, and other family members, to the difference
between a CO reading and and indication signifying a problem with the
unit itself.
NOTE: When AC power is restored, the alarm will automatically switch
back to normal operating mode.
The alarm will not detect CO or gas if battery is depleted. Replace bat-
tery.
