Guidance and manufacturer’s declaration – electromagnetic immunity
The system is intended for use in the electromagnetic environment specified below.
The customer or the user of the system should assure that it is used in such an environment.

equipment should be used
no closer to any part of the
system, including its cables,
than the recommended
separation distance
calculated from the
equation applicable to the
frequency of the
transmitter.
Recommended separation
distance
d = 1.17√P
d = 1.17√P 80 MHz to 800
MHz
d = 2.33√P 800 MHz to 2.7
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:
a) 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.

NOTE 1: At 80 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.
c) 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 shall be considered. If the measured field strength in the location in which the
system is used exceeds the applicable RF compliance level above, the system shall be
