Care and maintenance, Manufacture date
· 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.
· Do not use flammable liquids for cleaning the alarm!
Maintenance
· The electrochemical sensor is subject to ageing. The sensor
lifespan is thereby limited to 7 years.
· The sensor cannot be exchanged. For this reason, replace the
entire device 7 years after the date of its installation at the
latest. (See label on the rear side of the alarm).

There is a 21-digit bar code on the back of the alarm from
which the date of manufacture and the software version of the
alarm can be derived.
Positions 11, 12 and 21 of the bar code are relevant here:

Example:
Battery replacement
1. To mount on the wall: Push the CO alarm upwards to
detach it from the mounting base.
2. Remove the two flat batteries and replace them with two
new AA-batteries into the two compartments ensuring
they are the right way round - the warning tone will sound.
The CO alarm is ready for operation again.
