The device is subjected to different safety tests
before delivery and marked with a seal. If a de-

peated. A guarantee is only provided for unope-
ned devices.

taken by the manufacturer.
Front film
Cleaning the front film can be done with a soft
cloth and domestic detergent. Acids and pro-

and maximum values and events.
The expected battery life is at least 5 years at a
storage temperature of +45°C. The typical bat-
tery life is 8 to 10 years.
The device must be opened to exchange the
battery. If the device has been opened, a new
safety test is required for safe operation. A gu-
arantee is only provided for unopened devices.
