and clean place.

eration voltage of the equipment and that the lamp switch is in o-position.
Users should observe all safety regulations of the region. The equipment has acquired the CE safety label. How-
ever, users do have full responsibility to use this equipment safely.
Cleaning the optics
If the optical parts need to be cleaned try rst to: use compressed air. If that is not sucient: use a soft lint-free
piece of cloth with water and a mild detergent. And as a nal option: use the piece of cloth moistened with a 3:7
mixture of ethanol and ether.
Note: ethanol and ether are highly ammable liquids. Do not use them near a heat source, near sparks
