Safety informaon and use

WARNING

Laser radiaon!

Laser devices of laser class 3B and 4 are dangerous for the

human eye, so that even an exposure me of 0.25 sec is suf-

cient to cause permanent damage to the rena. Therefore

it is mandatory for every person who is operang the device

with the housing open during repairs or maintenance to wear

suitable safety goggles. The safety goggles must be suitable for

the wavelength of the laser being used.

WARNING

Laser radiaon!

−Never look directly into the laser beam.

−Always avoid placing any reecve objects in the laser

beam.

−Wear suitable safety goggles during maintenance and

adjustment work on the open laser emier. (< 10 mW,

532 nm).

It is not necessary to appoint a laser safety ocer for the ANALYSETTE 22 as the

laser radiaon sources are fully enclosed and not accessible.

The ANALYSETTE 22 is classied in laser protecon class 1 according to EN 60825.
