5.3 Precautions for a safe use
- Beforeplugginginthepowercordwiththesupply,makesurethatthesupplyingvoltageofyourregion
matcheswiththeoperationvoltageoftheequipmentandthatthelampswitchisinoff-position.
- Donotturnthepoweronandoff,offandonimmediatelyasthiswillshortenthelifespanofthebulb
and may cause damage to the electrical system.
- Users should observe all safety regulations of the region. The equipment has acquired the CE safety

- 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ornearelectricequipment.Usethesechemicalsinawellventilatedroom.
- Remembertoneverwipethesurfaceofanyopticalitemswithyourhands.Fingerprintscandamage
