Electromagnetic environment - guidance
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
80 MHz to 800 MHz
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 metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,

be less than the compliance level in each frequency

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 Device is used exceeds the applicable RF compliance level above, the Device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the Device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the Device.
The Device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Device can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the Device
as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is
the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
