Guidance and manufacturer's declaration - electromagnetic immunity
The Neptune 3 Rover REF 0703-001-000 is intended for use in the electromagnetic environment specified below. The customer or the user of the
Neptune 3 Rover REF 0703-001-000 should assure that it is used in such an environment.
Immunity test
IEC 60601 test level
Compliance level
Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
3 Vrms
150 kHz to 80 MHz
3 V
Portable and mobile RF communications equipment should be used
no closer to any part of the Neptune 3 Rover REF 0703-001-000,
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d
=1.2√P
150 kHz to 80 MHz
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 metres (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

Interference may occur in the vicinity of equipment marked with the
following symbol:
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
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
Neptune 3 Rover REF 0703-001-000 is used exceeds the applicable RF compliance level above, the Neptune 3 Rover REF 0703-001-000 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Neptune 3 Rover REF 0703-001-000.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
