MAINTENANCE AND CLEANING

• Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these
could damage the housing or even impair the functioning of the product.
• The device does not require maintenance apart from occasional cleaning and changing the
batteries.
• Use a soft, slightly damp and lint-free cloth to clean the device.
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the
household waste.
At the end of its service life, dispose of the product according to the relevant
statutory regulations.
Remove any inserted batteries and dispose of them separately from the product.
b) Batteries
As the end user, you are required by law (Battery Ordinance) to return all used batteries;
disposal of them in the household waste is prohibited!
Contaminated batteries are labelled with this symbol to indicate that disposal in the
domestic waste is forbidden. The designations for the heavy metals involved are:
Cd = Cadmium, Hg = Mercury, Pb = Lead (name on batteries, e.g. below the trash
icon on the left).
Used batteries can be returned to collection points in your municipality, our stores or
wherever batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.
Solution
Place the thermometer in a room
with a stable ambient temperature
for approx. 30 minutes before taking
another measurement.
The device must be repaired. It may
be irreparable.
Remove the batteries to reset the
device. Replace the batteries and
check whether you can take a
measurement. If the error message
still appears, the device is defective.
