The MASTERPULS
®
ONE model is intended to be used in the electromagnetic environment specified
below. The customer or the user of the MASTERPULS
®
ONE should ensure that it is used in such an
environment.

Electromagnetic environment – guidelines
Portable and mobile RF equipment should be
used no closer to any part of the MASTERPULS
®
ONE, including cables, than the recommended
safety distance calculated from the equation ap-
plicable to the transmission frequency.

Where P is the rated power of the transmitter in
watts (W) according to the transmitter manufac-
turer and d is the recommended safety distance
in metres (m).
The field intensity of stationary radio transmit-
ters, based on an on-site inspection
a
should be
less than the compliance level.

Interference may occur in the vicinity of devices
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. The propagation of electromagnetic fields is influ-
enced by absorption and reflection from buildings, objects and people.
a. Field strengths 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 with respect to fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field intensity at the location in which the MASTERPULS
®
ONE is used exceeds the applicable RF compliance level
indicated above, the MASTERPULS
®
ONE should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the MASTERPULS
®
ONE.
b. Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
