The Laser system „3B LASER PEN 200 mW“ laser system is intended for use in the electromagnetic environment speci-
fied below. The customer or the user of the “3B LASER PEN 200 mW” laser system should assure that it is used in such an
environment.

Portable and mobile RF communi-
cations equipment should be used
no closer to any part of the “LA-X
PX” laser system, including cables,
than the recommended separation
distance calculated from the equa-
tion applicable to the frequency of
the transmitter.
Recommended separation distance:
80 MHz to 800 MHz
800 MHz to 2,5 GHz
Where P is the maximum output
power rating of the transmitter in
watts (W) according to the trans-
mitter manufacturer and d is the
recommended separation distance
in meters (m).
Field strength from fixed RF trans-
mitters, as determined by an elec-
tromagnetic site survey (a), should
be less than the compliance level in
each frequency range (b).
Interference may occur in the vicin-
ity of equipment marked with the
following symbol.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflec-
tion from structures, objects and people.
a) Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile ra-
dios, amateur radio, Am and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To as-
sess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered.
If the measured field strength in the location in which the “3B LASER PEN 200 mW” laser system should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the “3B LASER PEN 200 mW” laser system.
(b) Over the frequency range 150kHz to 80 MHz, field strength should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the „3B LASER
PEN 200 mW“ laser system.
