13. TROUBLESHOOTING
ALARM DOES NOT WORK WITH THE TEST BUTTON:
(1) Hold button down firmly for at least 5 seconds.
(2) Check the ‘pull’ tag is removed and/or the batteries are correctly connected.
(3) Replace batteries (if they are accessible).
ALARM BEEPS EVERY 45 SECONDS:
If the Alarm beeps every 45 seconds and green light flashes at the same time, then
the unit must be replaced if the ‘Replace by’ date on the side wall has been exceeded. If
it is not exceeded, and the batteries are accessible, replace the batteries.
If the Alarm beeps every 45 seconds and amber light flashes at the same time, then
the unit is probably defective. If the batteries are accessible, disconnect batteries
and/or press the test button. If problem persists, replace the unit.
ALARM SOUNDS FOR NO APPARENT REASON:
Follow the detailed instructions in section 2. entitled “What to do when the alarm
sounds” (page 4).
If there is still problems:
(1) Ensure there are no fuel burning appliances in the vicinity which could be leaking
CO gas (e.g. even from next door).
