TRV chair – Instructions for Use - EN Page 37
Portable and mobile RF communications equipment can affect the TRV. Install and operate the TRV
according to the EMC information presented in this chapter.
The TRV has been tested for EMC emissions and immunity as a standalone TRV. Do not use the TRV
adjacent to or stacked with other electronic equipment. If adjacent or stacked use is necessary, the user
should verify normal operation in the configuration.
The use of accessories, transducers and cables other than those specified, except for servicing parts sold
by Interacoustics A/S as replacement parts for internal components, may result in increased EMISSIONS
or decreased IMMUNITY of the device.
Anyone connecting additional equipment is responsible for making sure the system complies with the IEC
60601-1-2 standard.
Guidance and Manufacturer’s Declaration - Electromagnetic Emissions
The TRV is intended for use in the electromagnetic environment specified below. The customer or the
user of the TRV should assure that it is used in such an environment.
Electromagnetic environment - guidance
The TRV uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronic
The TRV is suitable for use in all commercial,
industrial, business and residential environments.

Recommended separation distances between
portable and mobile RF communications equipment and the TRV.
The TRV is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the
TRV can help prevent electromagnetic interferences by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the
TRV as recommended below, according to the maximum output power of the
communications equipment.

At 80 MHz and 800 MHZ, the higher frequency range applies.
These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
