conditions are defined as such:
- wetness or high humidity,
- dust and flammable gases, vapors or solvents,

b) (Rechargeable) batteries
• Correct polarity must be observed while inserting the (rechargeable) battery.
• The (rechargeable) battery should be removed from the device if it is not used
for a long period of time to avoid damage through leaking. Leaking or damaged
(rechargeable) batteries might cause acid burns when in contact with skin, Therefore

(rechargeable) batteries lying around, as there is risk, that children or pets swallow
them.

Never recharge non-rechargeable batteries. There is a risk of explosion!
c) Laser
• When operating the laser equipment, always make sure that the laser beam is
directed so that no one is in the projection area and that unintentionally reflected
beams (e.g. from reflective objects) cannot be directed into areas where people are
present.
• Laser radiation can be dangerous, if the laser beam or its reflection enters
unprotected eyes. Therefore, before using the laser equipment, familiarise yourself
with the statutory regulations and instructions for operating such a laser device.
