Guidance and manufacturer’s declaration—electromagnetic immunity
The C-Series Tango system is intended for use in the electromagnetic environment specified below. The
customer or the user of the C-Series Tango system should assure that the device is used in such an
environment.

Electromagnetic environment—
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the C-Series Tango system, 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
3 Vrms
150 kHz to 80 MHz
3 Vrms d = 1.17 √P
Radiated RF
IEC 61000-4-3
10 V/m
80 MHz to 2.5 GHz
10 V/m d = 0.35 √P 80 MHz to 800 MHz
d = 0.70 √P 800 MHz to 2.5 GHz
where P is the maximum output power rating
of the transm tter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in meters
(m).
Field strengths from fixed RF transm tters, as
determined by an electromagnetic site
survey,
a
should be less than the compliance
level in each frequency range.
b
Interference may occur in the vicin ty 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 s tuations. 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 transm tters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the C-Series Tango system is used exceeds the applicable RF compliance level above, the C-Series Tango
system should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the C-Series Tango system.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
