• Batteries contain harmful acids and may be hazardous if swallowed. If a battery is
swallowed, this can lead to serious internal burns and death within two hours. If
you suspect a battery could have been swallowed or otherwise caught in the body,
seek medical help immediately.
• Batteries must not be thrown into a fire, short-circuited, taken apart or recharged.
Risk of explosion!
• Low batteries should be changed as soon as possible to prevent damage caused
by leaking.
• Never use a combination of old and new batteries together, nor batteries of differ-
ent types.
• Avoid contact with skin, eyes and mucous membranes when handling leaking bat-
teries. In case of contact, immediately rinse the affected areas with water and con-
sult a doctor.
Important information on product safety!
• Do not expose the device to extreme temperatures, vibrations or shocks.
• Protect it from moisture.
The interaction of temperature and air humidity
Cold air however, can absorb only little moisture. Warm air can absorb much more
water vapor.
Dew-point
This interdependency of temperature and relative humidity is expressed by means of
the dew-point:
If the air is cooled continuously at constant absolute humidity, then the relative
humidity will steadily increase up to a maximum of 100%. If the air is cooled
further, then the excess water vapor is separated out in the form of water droplets.
If the measuring unit indicates an air temperature of 20° C and a relative humidity of
65%, then the dew-point temperature will be 13.2° C. What does that mean? That the
air, for instance in your bedroom, will condense and form water droplets at all points
on walls and ceilings that are cooler than 13.2° C, and that this may later lead to
patches of mould or damp stains.
If the air is at a relative humidity of say 40%, then the dew-point temperature is only 6
°C. The walls and ceilings would therefore have to be significantly colder for the air to
reach its dew-point and for water droplets to form.
