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