Portable and mobile RF communications equipment should be used
no closer to any part of Ebb, including cables, than the recommended
separation distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = [3.5/10] √P 80 MHz to 800 MHz
d = [7/10] √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, should be
less than the compliance level in each frequency range. 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.
• 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 Ebb is used exceeds the applicable RF compliance level
above, Ebb should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating Ebb.
