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