INJURY!
Do not leave flat batteries in the device. Even batteries protected against leaking
can corrode and thus release chemicals which may be detrimental to your health
or destroy the battery compartment.
Do not leave batteries lying around carelessly. They could be swallowed by
children or pets. If swallowed, consult a doctor immediately.
Remove the batteries if the device is not used for longer periods of time to pre-
vent leaking.
Leaking or damaged batteries may cause alkali burns if they come in contact with
the skin. It is therefore advisable to use suitable protective gloves.
Make sure that the batteries are not short-circuited. Do not throw batteries into
the fire.
Batteries must not be recharged or dismantled. Danger of explosion!
