Sony PVM-2551MD Instructions D'utilisation page 48

The PVM-2551MD/2551NB is intended for use in the electromagnetic environment specified below. The customer or the user of the
PVM-2551MD/2551NB should assure that it is used in such as environment.
Immunity test
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
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 PVM-2551MD/2551NB is used exceeds the applicable RF compliance level above, the PVM-2551MD/
2551NB should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the PVM-2551MD/2551NB.
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 part of the PVM-2551MD/2551NB,
including cables, than the recommended separation distance
calculated from the equation appliance 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 recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an
a
electromagnetic site survey, should be less than the compliance
b
level in each frequency range.
Interference may occur in the vicinity of equipment marked with
