EMC Information

EMC guidelines and manufacturer’s declaration

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.

Emissions test Compliance Electromagnetic environment – guidance

RF emissions

CISPR 11

Group 1

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.

Recommended separation distances between portable and mobile RF 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.

100 12 12 23

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.
