Do not throw rechargeable batteries into a fire or
expose to high temperatures. There is a risk of
explosion!
If handled improperly, a liquid may emerge from
rechargeable batteries that can cause skin irrita-
tion. Avoid contact with the liquid. Rinse skin with
large amounts of water if it comes into contact
with the liquid. If the liquid comes into contact with
eyes, rinse with water immediately for 10 minutes
and consult a doctor immediately!
WARNING!
Danger of death by electrocution!
Never touch an electrical outlet with wet hands!
Do not expose the power pack to moisture!
Never pull the cable to remove the power pack

cally.
It is only possible to switch on the camera again
after the battery has been replaced with a charged
battery or a power cable is connected to recharge
the battery in use.
