TABLE 3
Declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specied below. The customer or the
user of device should assure that it is used in such an environment.
Immunity test IEC 60601
test level
Compliance

Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
3V
0.15 MHz to
80MHz
6 V in ISM

between
0.15 MHz
and 80
MHz
Not
applicable
Portable and mobile RF communications equipment
should be used no closer to any part of device, than
the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter. Recommended separation distance
Radiated RF
IEC 61000-4-3
10 V/m
80 MHz to
2.7 GHz
10V/m d=1.2√P
150 KHz to 80 MHz
d=1.2√P
80 MHz to 800 MHz
d=2.3√P
80 MHz to 2.7 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 xed 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:
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 reection from structures, objects and people.
a. Field strengths from xed RF 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 xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld strength in the location in which
device is used exceeds the applicable RF compliance level above, device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating device.
b. Over the frequency range 0.15 MHz to 80 MHz, eld strengths should be less than 3 V/m.
