• Guidance and manufacturer's declaration – electromagnetic
immunity
The device is intended for use in the electromagnetic environments
listed below, and should only be used in such environments:
Immunity IEC 60601 Compliance
test test level level
Conducted 3 Vrms Not Ap-
RF 150 kHz to plicable
IEC 61000- 80 MHz
4-6 3 V/m
3 V/m
Radiated 80 MHz to
RF 2.5 GHz
IEC 61000-

Electromagnetic envi-
ronment – guidance
Portable and mobile RF
communications equip-
ment should be used no
closer to any part of the
device, including cables,
than the recommended
separation distance
calculated from the
equation applicable to
the frequency of the
transmitter.
Recommended separa-
tion distance
d = 1.2 80 MHz to
800 MHz
d = 2 .3 800 MHz
to 2.5 GHz
where P is the maximum
output power rating of the
transmitter in watts (W)
according to the transmit-
ter manufacturer and
d is the recommended
separation distance in
metres (m).
Field strengths from
fixed RF transmitters, as
determined by an elec-
tromagnetic 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:
29
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electro-
magnetic 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 loca-
tion in which the device is used exceeds the applicable RF compliance
level above, the device should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.
