Guidance and
manufacturer’s declaration – electromagnetic immunity (2)
The Otowave 102 Tympanometer is intended for use in the electromagnetic environment specified below.
The customer or user of the Otowave 102 Tympanometer should assure that it is used in such an
environment.
Immunity test
IEC 60601 test level
Compliance
level
Electromagnetic environment
– guidance
Radiated RF
IEC 61000-4-3
3 V/m
80MHz to 2.5GHz
3 V/m
Portable and mobile RF communications
equipment should be used no closer to any
part of the Otowave 102 Tympanometer,
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 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 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.
b
Interference may occur in the vicinity of
equipment marked with the following
symbol:
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.
