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 as below.
Recommended separation distance:
d=1.2/V1]√P
d=1.2/√P 80 MHz to 800MHz
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 separation
distance in meters (m).

Interference may occur in the vicinity of equipment
marked with the following symbol:
a
The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz
to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
b
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.
