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 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 due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the BW-PFX1 is used exceeds the applicable RF compliance level above, the DEVICE should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the DEVICE.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer to any
part of the BW-PFX1, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d = 1,2√P
d = 1,2√P 80 MHz to 800 MHz
d = 2,3√P 800 MHz to 2,5 GHz
Where P is the maximum output power rating
of the transmitter in watts (W) according to the
transmitter manufacturer and d is the recom-
mended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
survey , should be less than the compliance
a
level in each frequency range .

Interference may occur in the vicinity of
equipment marked with the following symbol:
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE DEVICE .
The BW-PFX1 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled.
The customer or the user of the BW-PFX1 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and
the BW-PFX1 as recommended below, according to the maximum output power of the communications

For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
