The lid of the battery compartment is located on
the rear side of the appliance. Replace the three
C-type batteries by pushing the lid of the bat-
tery compartment to the rear and replacing the
spent batteries with new ones. Then carefully
close the battery compartment again.
06. Care and maintenance
Clean the device if necessary with a moist, soft, lint-free cloth.
Take care that no moisture enters the housing. Do not use
sprays, solvents, cleaning agents containing alcohol or scouring
agents; use only clean water to moisten the cloth.

cordance with the applicable legal regulations when its service
life is ended.

Moving the appliance from a cold to a warm environment (and vice
versa) can lead to the formation of condensation on the measuring
circuitry of the appliance. This physical effect, which cannot be pre-
vented by structural means for any measuring instrument, leads to
false measurement values. Depending on the extent of the tempe-
rature difference, the appliance will require an 'acclimatisation time'
of approx. 15-30 min. before the measurement procedure can be
resumed.

Extreme humidity or heat can damage the sensor.
