Sony DXC-C33P Instructions For Use Manual page 7

Guidance and manufacturer's declaration - electromagnetic immunity
The DXC-C33P is intended for use in the electromagnetic environment specified below. The
customer or the user of the DXC-C33P should assure that it is used in such as environment.
Immunity test IEC 60601 test
level
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 DXC-C33P is used
exceeds the applicable RF compliance level above, the DXC-C33P should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the DXC-C33P.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment - guidance
level
Portable and mobile RF communications
equipment should be used no closer to any
part of the DXC-C33P, 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
3 Vrms
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 800 MHz to 2.5 GHz
3 V/m 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).
