Standards and lEC Classifications
The CUSA EXcel is intended for use in the electromagnetic environment specified below. The customer or the user of the CUSA
EXcel should assure that it is used in such an environment.

Portable and mobile RF
communications equipment should be
used no claser to any part of the CUSA
EXcel, including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
Conducted RF

IEC 61000-4-6
150KHz to 80MHz
Radiated RF IEC
3 V/m

d=0.5VP 80MHz to 800MHz

80MHz to 2.5GHz
d=VP 800MHz to 2.5GHz
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
lass than the compliance level in each
frequency range
Interference may occur in the vicinity of
equipment marked with the following
symbol:
O)
NOTE 1 At a80MHz and 800MHz, 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.
a. 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 CUSA EXcel is used exceeds the applicable RF compliance level above, the CUSA EXcel
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the CUSA EXcel.
b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
