EMC Information
(Electromagnetic Compatibility Information)
Guidance and manufacturer’s declaration - Electromagnetic Immunity
The product is intended for use in the electromagnetic environment specified below. The customer or the user of the product should
assure that it is used in such an environment.
Immunity test
IEC/EN60601 test level
Compliance level
Electromagnetic environment – guidance
Conducted RF
EN/IEC61000-4-6
3Vrms
150kHz to 80MHz
3Vrms
Portable and mobile RF communications
equipment should be used no closer to
any part of the product, 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
d=1.2 √P
80MHz to
800MHz
d=2.3 √P
800MHz to
2.5GHz
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 electromagnetic site survey(a)
should be less than the compliance level
in each frequency range(b). Interference
may occur in the vicinity of equipment
marked with the following symbol:
Radiated RF
EN/IEC61000-4-3
3V/m
80MHz to 2.5GHz
3V/m
NOTE 1: At 80MHz and 800MHz, 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 product is used exceeds the applicable RF compliance level stated above, the product should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the product.
b: Over the frequency range 150kHz to 80MHz, the field strength should be less than 3V/m.
