Use and Care Manual

disconnected, or if the battery’s power is low, a red LED flash will occur
once every 60 seconds, accompanied by an audible beep. If this
happens, the battery must be replaced. (For model KN-COP-IC with
digital display: “Lb” will be displayed alternately with the current CO
reading once every second).
IMPORTANT: Constant exposures to high or low humidity may reduce
battery life. A good safety measure is to replace the battery at least once
a year, or at the same time as you change your clocks for daylight saving
time.
End of Life Notification
Seven (7) years after unit is first powered, this alarm will “beep” every 30
seconds and display "End" to indicate that it is time to replace the alarm
(see Alarm Removal section for instructions). By pressing the Test/Reset
button the audible notification will be silenced for up to two days giving you
time to replace the unit at a more convenient time. The display will alternate
between the the CO ppm reading and "End" to remind you to replace the
unit right away. This silence feature can only be used for a few days before
it will no longer function and the beep cannot be silenced. The alarm will
still monitor and alarm for CO during this period but all other functionality
will be lost.
Alarm Removal
