7. Maintenance
NOTE: This unit is sealed. The cover is not removable.
Due to the loudness of the alarm, we suggest that you place your
fingers over the sounder opening while testing your alarm.
CAUTION: Continuous exposure to the high sound level of this
alarm over an extended period of time may cause hearing loss.
Testing
Observe the alarm weekly to make sure the red dot is blinking, indicat-
ing normal operation.
If the dot is not blinking, unplug the alarm for three minutes, then plug
in again. This will clear the alarm for restart. If the dot does not resume
blinking, your alarm may be malfunctioning.
To test the alarm,press the Test/Reset button. If the alarm is operating
properly, you will notice the following:
• The display shows three “eights”, then shows the word “GAS” while
the alarm is sounding three short “beeps”. Then, the display shows a
number (usually around 200). You will then hear four quick “beeps” –
followed by five seconds of silence – followed by four quick “beeps”
repeating until reset stops. The unit will then show three “eights” for
several seconds. It will then return to monitoring for CO and gas.
Familiarize yourself and household members with the alarm pattern
described above for a CO or gas event. While on AC power, in the event
of a CO or gas incident, the appropriate pattern will continue to repeat
as long as CO or gas is present.
NOTE: Pressing the Test/Reset button tests the functions of the alarm’s
internal components, circuitry and micro-computer. You do not need
to press the Test/Reset button to take a CO or gas reading.CO
readings or the presence of gas are automatically shown on the alarm’s
digital display. If the alarm shows “0”, then no measurable amount of
CO or gas has been sensed by the alarm within the past 15 seconds.

this alarm is equipped with 9 volt battery backup – the 9 volt battery is
to supply short term back-up during a power outage.
