Guidance and manufacturer's declaration - electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below. The customer or the user of the device sho
uld assure that it is used in such an
Immunity test

Compliance level Electromagnetic environment - guidance
-4-3
Portable and mobile RF communications equipment
should be used no closer to any part of the Device
,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter
.
Recommended separation distance
d = 1.167
80 MHz to 800 MHz
.333 800 MHz to 2.5 GHz
Where Pis 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:
: At 80 MHz and 800 MHz, the higher frequency range applies.
: 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. lf the measured field strength in the location in which the Device is used exceeds the applicable RF compliance level above, the Device should be
observed to verify normal operation. If normal performance is observed, additional measures may be necessary, such as reorienting or relocating the Device. b Over the
frequency range 150 kHz to 80 MHz, field strengths should be less than [Vii V/m].
