Recommended distances between portable and mobile RF communications equipment and the EliteVue
The EliteVue is intended for use in an electromagnetic environment in which RF emissions are controlled.
The customer or user of the EliteVue can help to avoid electromagnetic interference by observing the mini-
mum distance between portable and mobile RF communications equipment (transmitters) and the EliteVue
in accordance with the maximum output power of the communication equipment.

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

Portable and mobile RF communica-
tions equipment should not be used
closer to any part of the non-contact
EliteVue, including the cables, than
the recommended distance, which is
calculated using the equation applica-
ble to the transmitter frequency.
Recommended separation distance
d = 1.2 × P 80 MHz to 800 MHz
d = 2.3 × P 800 MHz to 2.7 GHz
Where P is the maximum output
power of the transmitter in watts (W)
according to the transmitter manufac-
turer and the recommended distance
is given in meters (m).
Field strengths from fixed RF
transmitters determined by an
electromagnetic site survey should be
less than the compliance level in each
frequency range.
Interference may occur in the vicinity
of devices 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. The electromagnetic propagation is affected by
absorption and reflection of structures, objects and people.
a)
Field strengths of fixed transmitters, such as base stations for radio (cellular/wireless) telephones
and land mobile radios, amateur radio, AM and FM broadcast and television transmissions, cannot be
theoretically predicted with accuracy. In order to assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic survey should be considered. If the measured field strength at the
location where the EliteVue is used exceeds the above-mentioned RF degree of compliance, the EliteVue
should be observed to ensure normal operation. If abnormal performance is observed, additional measu-
res may be required, such as reorienting or moving the EliteVue.
b)
With a frequency range over 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
