Class 1 Laser; Product Overview - Hach LANGE HIAC 9703+ User Manual

1. Disconnect the equipment from its power source to verify that it is or
is not the source of the interference.
2. If the equipment is connected to the same outlet as the device
experiencing interference, connect the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the
interference.
5. Try combinations of the above.

Class 1 laser

A Class 1 laser is installed in this instrument. Class 1 lasers are products
where the radiant power of the laser beam accessible (the accessible
emission) is always below the Maximum Permissible Exposure value.
Therefore, for Class 1 lasers the output power is below the level at which
it is believed eye damage will occur. Exposure to the beam of a Class 1
laser will not result in eye injury. Class 1 lasers may therefore be
considered safe. However, Class 1 laser products may contain laser
systems of a higher class but there are adequate engineering control
measures to ensure that access to the beam is not reasonably likely. This
Class 1 laser product complies with 21 CFR Chapter 1, subchapter J. It is
evaluated and tested in accordance with EN 61010-1, Safety
Requirements for Electrical Equipment for Measurement and Control and
Laboratory Use and IEC/EN 60825-1, Safety of Laser Products.
