b) Batteries and rechargeable batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Make sure that the polarity (plus/+ and minus/-) is correct when inserting batteries/
rechargeable batteries into the ‘FS20 STR’ wireless thermostat. You will find a correspond-
ing figure in the battery compartment.
• Do not leave batteries/rechargeable batteries lying around as they could be swallowed by
children or pets. In such case seek immediate medical care.
• Leaking or damaged batteries/rechargeable batteries may cause acid burns, if they come
into contact with skin. Therefore, please make sure you use suitable protective gloves.
• Make sure that batteries/rechargeable batteries are not short-circuited or thrown into a fire.
They might explode!
• Never disassemble batteries/rechargeable batteries!
• Conventional batteries must not be recharged. They might explode!
• If the device is not used for a longer period of time (when stored, for example), remove the
inserted batteries/rechargeable batteries to prevent them from leaking and causing
damage.
The ‘FS20 STR’ wireless thermostat can be powered using rechargeable
batteries. However, due to their lower voltage (rechargeable battery = 1.2V,
battery = 1.5V) and lower capacity, the period of operation and wireless range
are reduced.
Therefore, to ensure safe operation, please only use high-quality alkaline
batteries.
