FCC statement (applicable in U.S.)
Thisequipmenthasbeentestedand 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 instal-
lation.Thisequipmentgenerates,usesand
can radiate radio frequency energy and, if
not installed and used in accordance with
the instructions, may cause harmful inter-
ference to radio communications.
However, there is no guarantee that inter-
ference will not occur in a particular instal-
lation. 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 interfer-
ence 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 : 2007 „Radiation safety of
laser products“
Laser Class 2 products:
Do not stare into the laser beam or direct it
towards other people unnecessarily. Eye
protectionis normallyafforded byaversion
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.
