10. Servicing and cleaning
The device is maintenance-free for you (except for occasional,
necessary replacement of batteries). For this reason, you should
never open it.
Clean the product with a clean, soft and dry cloth. Do not scratch
the LC display.
For more resistant contamination, you can moisten the cloth
slightly with lukewarm water.
Do not use detergents or coloration of the plastic
material could occur. This could also damage the
labelling.
11. Disposal
a) General
If the product becomes unusable, dispose of it in accordance
with the relevant statutory regulations.
b) Battery/accumulator disposal
You, as the ultimate user, are required by law (Battery Ordi-
nance) to return all used batteries/accumulators. Disposing of
flat batteries/accumulators in the household waste is pro-
hibited!
Batteries / accumulators which contain hazardous
substances are marked by the symbols on the side.
These symbols also indicate that it is prohibited to
dispose of these batteries in the household waste.
The names for the decisive heavy metals are:
Cd=cadmium, Hg=mercury, Pb=lead (the designa-
tion is written on the accumulator e.g. under the
rubbish can symbols depicted at the left).
You can hand in your used batteries/accumulators
at the official collection points of your community at
no cost or everywhere where batteries/accumula-
tors are sold.
You thus fulfil your statutory obligations and make your contribu-
tion to the protection of the environment.
