When empty batteries are indicated, the batteries should be replaced as
soon as possible.
Use a Lithium battery (1 x CR1123A, 3V). Rechargeable batteries are not
suitable.
With both the supplied batteries and most A brand batteries on the market,
it will take approximately three years before it is empty.
REASON FOR SENSOR FAULT:
Faults can be caused by broken circuitry, a faulty sensor or faulty electronic
parts.
SENSOR FAULT CAUSED BY CHEMICAL GASES:
When volatile chemical gases such as alcohol are the cause for error
detection, this may be corrected by switching the detector off and leave it in
fresh air for 24 hours. This will restore the sensor. If the error is not cleared
after these 24 hours, the detector is faulty and should be replaced. Don't
repair the detector yourself, but have it repaired by the importer.
When the alarm is contaminated and damaged by high concentrations of
chemical gases, the sensor could be affected. This will lead to a temporary
error or permanent damage. When the alarm sounds and you can smell a
chemical gas, this could be the reason. Carbon monoxide is a colourless
and odourless gas. Chemical gases do have an odour.
The following substances and gases can cause false alarms or permanently
damage the detector: Methane, propane, iso-butane, ethylene, ethanol,
alcohol, iso-propanol, benzene, toluene, acid, ether, hydrogen, hepatic gas,
sulphur dioxide, aerosol, propellant, alcohol preparation, paint, thinner,
dissolvent, bonding agents, shampoo, aftershave balm, perfume, car
exhaust (cold start) and certain cleaning agents.
