boso Medicus Smart Mode D'emploi page 33

The boso unit is intended for use in the electromagnetic environment specified below. The customer or the user of the boso unit should
assure that it is used in such an environment.

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 boso unit is used exceeds the applicable RF compliance level above, the boso unit should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such als re-orienting or relocating the
boso unit.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be
used no closer to any party of the boso unit, 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 transmit-
ter in watts (W) according to the transmitter manufacturer
and d is the recommended separation distance in metres
(m).
