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

Portable and mobile rF communications equipment
should be used no closer to any part of the table, in-
cluding cables, than the recommended separation
distance calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d = 1.2 √ P
d = 1.2 √ P 80 MHz to 800 MHz
d = 2.3 √ P 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 separa-
tion distance in meters (m).
Field strengths from fixed RF transmitters, as deter-
mined 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 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 accura-
cy. 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 table is used exceeds the applicable RF com-
pliance level above, the table should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the table
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
