⚠
Caution! In the unlikely event of a failure in the internal protection circuitry, there is a risk of
explosion when charging a fully or partially discharged battery. Replace the battery when it no
longer has a sufficient charge for unit operation. Control the battery before use if the device has
not been used for an extended period.
⚠
Caution! Risk of explosion if the battery is replaced with an incorrect type. Dispose of used
batteries according to the instructions!
