Propaq Encore Monitor: Guidance and Manufacturer’s Declaration—Electromagnetic Immunity

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

Electromagnetic Environment—Guidance

Portable and mobile RF communications equipment
should be used no closer to any part of the monitor,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey

, should

be less than the compliance level in each frequency
range

b

.

Interference might occur in the vicinity of equipment
marked with the following symbol:

Note 1

At 80 MHz and 800 MHz, the higher frequency range applies.

Note 2

These guidelines might 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 monitor is used exceeds the applicable RF compliance level
above, the monitor should be observed to verify normal operation. If abnormal performance is
observed, additional measures might be necessary, such as reorienting or relocating the monitor.

b

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