cating the alarm is in the start-up mode. The three “eights” will remain
for approximately 30 seconds. Then, the alarm will display “0” and
begin monitoring the air for CO and will continue to do so as long as it
receives power.
This alarm will display a “0” if CO concentrations between 0 and 30
PPM have been detected within the last 15 seconds.
