Guidance and manufacturer’s declaration: electromagnetic immunity
The PBSV4.1 bladder scanner is intended for use in the electromagnetic environment specified below.
The customer or the user of the PBSV4.1 bladder scanner should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should not be used close to any
part of the PBSV4.1 bladder scanner,
including
cables
( o t h e r

the
recommended separation distance calculated
from 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 and
d
is the
recommended separation distance in meters
(m).
Field strengths 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: At 80MHz and 800MHz, the higher frequency range applies.
NOTE: 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 PBSV4.1 bladder scanner is used exceeds the applicable RF compliance level above, the PBSV4.1
bladder scanner should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the PBSV4.1 bladder scanner.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
