EMC GUIDANCE & MANUF ACTURER’S DECLARATION
55 OTOWAVE 302+ INSTRUCTION FOR USE
Guidance and manufacturer’s declaration – electromagnetic immunity (2)
The Otowave 302+ Tympanometer is intended for use in the electromagnetic environment specified below. The
customer or user of the Otowave 302+ Tympanometer should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of the Otowave 302+
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
d = 1.2√P (80MHz to 800MHz0
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.
