FCC statement (applicable in U.S.)
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Laser classification
The device produces visible laser beams, which are emitted from the instrument:
It is a Class 2 laser product in accordance with:
- IEC60825-1 : 2014 „Radiation safety of laser products“
Laser Class 2 products:
Do not stare into the laser beam or direct it towards other people
unnecessarily. Eye protection is normally afforded by aversion responses
including the blink reflex.
WARNING
Looking directly into the beam with optical aids (e.g. binoculars, telescopes)
can be hazardous.
CAUTION
Looking into the laser beam may be hazardous to the eyes.
