Conducted RF IEC 61000-
4-6
3 Vrms 0.15MHz to 80MHz 3Vrms
Portable and mobile RF
communications equipment can
interfere with the Umana T1
communication. This type of
equipment, including cables,
should be kept distant from the
Umana T1 with at least the
recommended
separation
distance calculated from the
equation appropriate for the
frequency of the transmitter.
Recommended Separation
Distance
d=1,2 P
d=1,2 P 80 MHz to 800
MHz d=2,3 P 800MHz to
2,5 GHz
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
(a), should be less than the
compliance
level in each
frequency range (b).
Interference may occur in the
vicinity of equipment marked
with the following symbol:
(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 outside the shielded location in which the Umana T1 is used exceeds the applicable RF compliance level
above, the Umana T1 should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the Umana T1.
(a)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
The Umana T1 is intended to be used in a controlled radiated RF environment. Users can help prevent electromagnetic
interference by keeping a minimum distance between the portable RF device (transmitted) and the Umana T1 as recommended
below, according to the maximum output power of the communications device.
