⚠
Caution! In the unlikely event of a failure in the internal protection circuitry, there is a risk of an explosion
when charging a fully or partially discharged battery. Replace the battery when it no longer has a
sufficient charge for unit operation. Check 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 incorrect type. Dispose battery according to rules!
