3B LASER PEN 200 Operating Instructions Manual - page 23
The „3B Laser“ is intended for use in the electromagnetic environment specified below. The customer or the user of the
“3B Laser” should assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Compliance level

Portable and mobile RF communications
equipment should be used no closer to any part
of the LDU8021PN laser system, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:

Where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in meters
(m).
Field strength from fixed RF transmitters, as
determined by an electromagnetic site survey
(a), should be less than the compliance level in
each frequency range (b).
Interference may occur in
the
vicinity 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
reflection from structures, objects and people.
(a) Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, Am and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess 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 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.
(b) Over the frequency range 150kHz to 80 MHz, field strength should be less than 3 V/m.
