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
E = [6/d] √P
d = [6/E] √P
where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer, d is the
recommended separation distance in meters (m), and E is the
field strength in V/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: 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.
Recommended separation distances between portable and mobile RF communications equipment as well as RF wireless
communications equipment Ebb
Ebb is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
Ebb can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and Ebb 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 meters (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 absorption and reflection from structures, objects
and people.
