Part Six – Display Reading and What They Mean

Page 6-3 and 6-4 contain vital information about the various readings you may see on your display. We suggest you keep this User’s Guide handy for reference.

Your new Nighthawk carbon monoxide alarm is a sophisticat- ed electronic device – yet very simple to understand. Basically, the unit will display a “0” if it does not sense carbon monox- ide and if you have a good 9V backup battery installed.

If it senses carbon monoxide, it will display a reading so you can see if you have a non-threatening or emergency situation.

However, if the backup battery is low or missing, or if the unit malfunctions it will display other readings (and alarm differ- ently) 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.
