Guidance and Manufacturer's Declaration—Electromagnetic Immunity

The AV500 is intended for use in the electromagnetic environment specified below. The customer or the user of the AV500 should assure that it is used in such an environment.

Guidance and Manufacturer's Declaration – Electromagnetic Immunity

The AV500 is intended for use in the electromagnetic environment specified below. The customer or the user of the AV500 should assure that it is used in such an environment.

IEC 61000-4-3

80 MHz to 2.5 GHz

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.

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 AV500 is used exceeds the applicable RF compliance level above the AV500 should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the AV500. Over the frequency range 150 kHz to 80 MHz,

field strengths should be less than 3 V/m.

Electromagnetic Environment

3 Vrms

Portable and mobile RF communications equipment should be used no closer to any part of the AV500,

including cables, than the recommended separation distance calculated from the equation applicable to the

frequency of the transmitter. Recommended separation distance

3 V/m

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, should be less than the compliance level in each

frequency range. Interference may occur in the vicinity of equipment marked with the following symbol:

Electromagnetic environment – guidance

Floors should be wood, concrete, or ceramic tile. If floors are covered with synthetic

material, the relative humidity should be at least 30 %.

Mains power quality should be that of a typical commercial or hospital environment.

Mains power quality should be that of a typical commercial or hospital environment. If

the user of the AV500 requires continued operation during power mains interruptions, it

is recommended that the AV500 be powered from an uninterruptible power supply or a

battery.

Power frequency magnetic fields should be at levels characteristic of a typical location in a

typical commercial or hospital environment.
