Troubleshooting
Test: If the CO alarm does not react after a functional test has been performed, first
check that the batteries are inserted correctly (polarity).
If the detector does not react to a new function test even after this, please contact
your dealer.
Weak batteries: If the CO alarm signals low battery performance, replace the
batteries immediately, at the latest within 7 days. Only use 1,5 V brand alkaline AA
batteries of the same type.
Malfunction: If the CO alarm registers a sensor error, the complete alarm must be
replaced - the sensor cannot be replaced!
The end of sensor lifespan: The lifespan of the electrochemical sensor is 10 years.
If the end of the lifespan is reached, the complete alarm must be replaced
immediately!
Care and maintenance
Cleaning
· Dusty detectors must be cleaned. You can clean dust from the air vents
of the detector using a vacuum cleaner or compressed air.
· If necessary, you can remove the dust with a brush.
· You can clean the surface using a cloth slightly dampened in soapy water.
· Do not allow water to penetrate inside the device!
· Do not clean the device in a dishwasher!
· Do not use sharp, pointed, abrasive, caustic or corrosive cleaning
materials or hard brushes!
· Do not use chemicals. The following substances can impair sensor
function and trigger false alarms: Methane, propane, isobutane,
isopropanol, ethylene glycol, benzene, toluene, ethyl acetate, hydrogen
sulphide, sulphur dioxide, products with an alcohol base, dyes,
thinners, solvents, adhesives, hairsprays and cleaning products.
