Kidde KN-COPD-3-UK - Manual (Page 25)

The following tables contain vital information about the vari-
ous readings you may see on your display. We suggest you
keep this User’s Guide handy for reference.
Your new Kidde Carbon Monoxide Alarm is a sophisticated
electronic device – yet very simple to understand. Basically,
the unit will display a “0” if it does not sense CO and if you
have a good 9 volt backup battery installed.
If your alarm senses carbon monoxide, it will display a read-
ing in parts per million of CO.
If the backup battery is low or missing, or if the unit malfunc-
tions it will display other readings (and alarm differently) to
alert you that something is wrong with the alarm.
Please familiarize yourself and other family members to the
difference between a CO reading and a reading signifying a
problem with the alarm itself.
