EMC GUIDANCE & MANUFACTURER’S DECLARATION
53 OTOWAVE 302+ INSTRUCTION FOR USE
Guidance and manufacturer’s declaration – electromagnetic emissions
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.
Electromagnetic environment – guidance
The Otowave 302+ Tympanometer uses RF energy only
for its internal function. Therefore, its RF emissions are
very low and are not likely to cause interference in
nearby electronic equipment.
The Otowave 302+ Tympanometer is suitable for use in
all establishments, other than domestic and those
directly connected to the public low-voltage power
supply network that supplies buildings used for domestic
purposes.
