Safety Instructions

FCC statement (applicable in

U.S.)

Laser classification

Labelling

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 reason-

able 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 interfer-

ence will not occur in a particular installation.

If this equipment does cause harmful interfer-

ence 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:

Laser Radiation

Do not stare into the beam

Laser class 2

acc. IEC 60825-1:2007

Maximum radiant power: <1mW

Emitted wavelength: 620-690nm

Beam divergence: 0.16 x 0.6 mrad

Impulse duration: 0.2 x 10^-9s - 0.8 x 10^-9

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

protection is normally afforded by aversion

responses including the blink reflex.

ƽWARNING

• Reorient or relocate the receiving antenna.

• Increase the separation between the

equipment and receiver.

Looking directly into the beam with optical

aids (e.g. binoculars, telescopes) can be

hazardous.

• 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.

ƽCAUTION

Looking into the laser beam may be

hazardous to the eyes.
