BATTERY INFORMATION INDICATION:
1. Every 24 seconds, the battery is checked automatically.
2. Every 24 seconds, the green power LED will flash for as long as the battery power is higher than 3.5
Volts. This means the battery capacity is sufficient. As soon as the battery power drops below 3.5
Volts, a beep tone will be emitted when the yellow LED flashes briefly. At that time, please replace the
batteries as soon as possible.
When empty batteries are indicated, the batteries should be replaced as soon as possible.
Use High Energy Alkaline batteries (3 x LR6 / 1.5V AA). Rechargeable batteries are not suitable.
With both the supplied batteries and most A brand batteries on the market, it will take approximately
eighteen months before these are 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.
