Declaration – electromagnetic immunity – for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING

Guidance and manufacturer's declaration – electromagnetic immunity

The MAT1210001 is intended for use in the electromagnetic environment specified below.

The customer or the user of the system should ensure that it is used in such an environment.

NOTE 1

At 80 MHz and 800 MHz, 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.

a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,

amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the

electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured

field strength in the location in which the Span system is used exceeds the applicable RF compliance level above, the system should

be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as

reorienting or relocating the system.

b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.

Portable and mobile RF communications equipment

should be used no closer to any part of the CT515,

including cables, than the recommended separation

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 meters (m).

Field strengths from fixed RF transmitters, as

determined by an electromagnetic site survey,

be less than the compliance level in each frequency

range.

Interference may occur in the vicinity of equipment

marked with the following symbol:

Recommended separation distances between portable and mobile RF communications equipment and the MAT1210001

Alternating Control Unit

The MAT1210001 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.

The customer or the user of the system can help prevent electromagnetic interference by maintaining a minimum distance between

portable and mobile RF communications equipment (transmitters) and the system 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 meters (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.
