6. Operating Characteristics
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
To test the alarm, press the Test/Hush button. If the unit is operating
properly, you will hear 4 quick beeps – followed by the voice message
"Warning, Carbon Monoxide!” – followed by 4 quick beeps. The display
will show in sequence "---" then "888". Within several seconds the unit
will return to monitor for CO.
Note: You do not need to press the Test button to take a CO
reading.
Maintenance Tips
To keep your alarm in good working order, you must follow these steps:
• Test the alarm once a week by pressing the Test/Reset button.
• Vacuum the alarm cover once a month to remove accumulated dust.
• Never use detergents or solvents to clean the alarm. Chemicals can
permanently damage or temporarily contaminate the sensor.
Peak Level Memory Reset
Press and hold the Peak Level button, then press and hold the Test/Hush
button. When the number on the display reads "0", release both
buttons. The memory will be cleared and the alarm will begin
monitoring for CO.
Discharge
At end of unit life, locate the
deactivation/discharge switch and push the
switch in the direction shown, until switch
clicks into place. This will silence the end of
unit life or low battery chirping, drain the
battery, and render the unit safe for disposal.
