7. Instructions relevant to batteries and
rechargeable batteries
In general, it is possible to operate the sensor with rechargeable batteries.
However, due to the lower voltage of rechargeable batteries (rechargeable
battery = 1.2V, battery = 1.5V) and the lower capacity there is a shorter
operating time, the radio range can also be reduced.
When outdoor temperatures are low, rechargeable batteries are more sensi-
tive than normal batteries.
This is why we especially recommend the use of high-quality alkaline batteries,
to allow a long and safe service life.
The sensor needs three batteries type AA/Mignon (e.g. Conrad item number
650117, order 3x).
• Keep batteries/rechargeable batteries out of reach of children.
• Please always observe correct polarity (positive/+ and negative/-) when
inserting the accumulators/batteries.
• Do not let batteries/rechargeable batteries lie around openly. There is a risk
of batteries being swallowed by children or pets. In such a case, seek
immediate medical care.
• Leaking or damaged batteries/rechargeable batteries might cause acid
burns when getting into contact with skin. Therefore, use suitable protective
gloves.
• Make sure that batteries/storage batteries are not short-circuited or thrown
into fire. They might explode!
• Conventional batteries must not be re-charged. They might explode! Only
charge rechargeable batteries meant for this purpose.
• In the case of disuse for a longer period of time (e.g. storage) take out the
inserted batteries/rechargeable batteries. Old batteries can leak and cause
damages.
• Always exchange the whole set of batteries/rechargeable batteries, only
use batteries/rechargeable batteries of the same type, by the same manu-
facturer and of the same charging state (don't mix full batteries with half-full
or empty batteries/rechargeable batteries).
• Never mix batteries and storage batteries.
• For the environmentally friendly disposal of batteries and rechargeable
batteries, please read the chapter "Disposal".
