Guidelines and manufacturer's declaration - electromagnetic immunity
The EliteVue model is intended for operation in the electromagnetic environment specifi ed below. The
customer or the user of the EliteVue device should ensure that it is used in such an environment.

Note 1: At 80 MHz and 800 MHz, the higher value applies.
Note 2 These guidelines may not apply in all situations. The propagation of electromagnetic waves is
infl uenced by refl ection and absorption by buildings, objects and people.
a The fi eld strength of stationary transmitters, such as base stations of wireless telephones and mobile
fi eld radio services, amateur radio stations, AM and FM radio and television transmitters, cannot be
precisely determined theoretically in advance. In order to determine the electromagnetic environment due
to stationary HF transmitters, an investigation of the location is advisable. If the fi eld strength determined
at the location of the EliteVue device exceeds the compliance level indicated above, then the EliteVue
device must be monitored with regard to its normal operation at each place where it is used. If unusual
performance characteristics are observed, additional measures such as re-alignment of the EliteVue
device or its removal to another place may be necessary.
b In the frequency range of 150 kHz to 80 MHz, the fi eld strength should be less than 3 V/m.
Recommended safety distances between portable and mobile HF communication
The EliteVue device is intended for operation in an electromagnetic environment in which the radiated HF
interference is monitored. The customer or the user of the EliteVue device can help prevent electromagnetic
interference by observing minimum distances between portable and mobile HF communication equipment
(transmitters) and the EliteVue device as recommended below, depending on the maximum output power of

For transmitters whose nominal power is not indicated in the table above, the distance can be determined
using the equation belonging to the respective column, where P is the nominal power of the transmitter in
Watts (W) as specifi ed by the manufacturer of the transmitter.
Note 1: At 80 MHz and 1000 MHz, the distance for the higher frequency range applies.
Note 2 These guidelines may not apply in all situations. The propagation of electromagnetic waves is infl uenced
by refl ection and absorption by buildings, objects and people.
