Sony LMD-X310MT Instructions For Use Manual page 6

Guidance and manufacturer's declaration – electromagnetic immunity
The LMD-X310MT/X550MT is intended for use in the electromagnetic environment specified below. The
customer or the user of the LMD-X310MT/X550MT should assure that it is used in such an 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 LMD-X310MT/X550MT is used exceeds the applicable RF compliance level above, the LMD-X310MT/
X550MT should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the LMD-X310MT/X550MT.
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 LMD-
X310MT/X550MT, including cables, than the
recommended separation distance calculated from
the equation appliance to the frequency of the
transmitter.
Recommended separation distance
= 1.2 √
= 1.2 √
80 MHz to 800 MHz
= 2.3 √
800 MHz to 2.5 GHz
Where is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
