Guidance and manufacturer's declaration - electromagnetic emissions
The EQUIPMENT is intended for use in the electromagnetic environment specified below.
The customer or the user of the EQUIPMENT should assure 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 EQUIPMENT is used exceeds the
applicable RF compliance level above, the EQUIPMENT should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the EQUIPMENT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment- guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the
EQUIPMENT, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distanced = 1.2ÖPd = 1.2ÖP
80 MHz to 800 MHzd = 2.3ÖP 800 MHz to 2.5 GHz
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. b Interference may occur in the
vicinity of equipment marked with the following
symbol:
Floors should be wood, concrete or ceramic tile. If
floors are covered with synthetic material, the relative
humidity should be at least 30%.
