Intended Use
The thermo-hygrometer indicates atmospheric humidity and ambient temperature. The product
is designed exclusively for use in dry environments.
Power is supplied via 2 x 1.5V mignon batteries (type: AAA). Do not use any other source of
energy. The correct battery type is specifi ed under "Technical Data". Any use other than the one
described above is inadmissible and damages this product. Misuse may also lead to risks such
as short circuiting and fi re. The safety instructions must be observed without fail. This product
complies with the applicable national and European specifi cations.

Information on Batteries and Rechargeable Batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Please observe the correct polarity (positive/+ and negative/-) when inserting
the batteries.
• Do not leave any batteries/rechargeable batteries lying around openly. There is
a risk of batteries being swallowed by children or pets. If swallowed, consult a
doctor immediately.
• Leaking or damaged batteries/rechargeable batteries may cause acid burns
if allowed to come into contact with the skin. Wear suitable protective gloves.
• Make sure that batteries/rechargeable batteries are not short-circuited, disman-
tled or thrown into fi re. There is a danger of explosion!
• Do not recharge normal batteries. There is a danger of explosion! Only charge
rechargeable batteries intended for this purpose; use a suitable battery charger.
• In you do not intend to use the product for a prolonged period (e.g. storage), re-
move the inserted batteries/rechargeable batteries. Old batteries can leak and
damage the device. This will invalidate the warranty/guarantee.
• Always replace the whole set of batteries/rechargeable batteries. Only use
batteries/rechargeable batteries of the same type/manufacturer with the same
charge state (do not combine full with semi-charged or empty batteries/re-
chargeable batteries).
• Never combine batteries and rechargeable batteries! Use either batteries or
rechargeable batteries.

for resetting the
When the display contrast weakens, the batteries are fl at and must be replaced as
described above. We recommend that all batteries are replaced once a year in order
guarantee optimised product function.
For a longer battery life, use only alkaline types ("hand" symbol). Due to the low volt-
age and capacity, the use of a rechargeable battery improves battery life.
If the room temperature does not appear within a few seconds, the batteries must be
removed for at least 30 seconds and then refi tted. Otherwise press the reset button
on the rear.
Do not install the product in the proximity of radiators, ovens windows or entrance
doors. The display of the temperature and relative atmospheric humidity can be falsi-
fi ed at these locations.
