Medical Electrical Equipment needs special precautions regarding EMC and needs to be
installed and put into service according to the EMC information provided in the following.
Portable and mobile RF communication equipment (e.g. cell phones) can affect Medical
Electrical Equipment.
The use of accessories and cables other than those specified (other than A&D original
parts) may result in increased emissions or decreased immunity of the unit.
Guidance and manufacturer's declaration – electromagnetic emissions
The A&D unit is intended for use in the electromagnetic environment specified below.
The customer or the user of the A&D unit should assure that it is used in such an
environment.

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

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable to
the frequency of the transmitter, where p is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.

Electromagnetic environment – guidance
The A&D unit 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 equipment.
The A&D unit is suitable for use in all
establishments, including domestic
establishments and those directly connected
to the public low-voltage power supply
network that supplies buildings used for
domestic purposes.
