Normal Operating Characteristics
When you first power up the unit, the alarm will sound briefly to let you
know the unit is receiving power and that the alarm circuit is functioning.
You will see three eights on the digital display, indicating the alarm is in the
start-up mode. The three eights will remain for approximately 20 seconds.
You will see a blinking red dot to the lower right of the digital display. The
blinking dot shows that the alarm is operating.
Within 20 seconds, your CO alarm will start monitoring for CO. The num-
ber indicates a measurement of carbon monoxide in parts per million
(ppm).
