Appendix A: EMC Information
Radiated RF EM 10 V/m 80 MHz to 2,7 GHz
Fields 80 % AM at 1 kHz
IEC61000-4-3
385-6000 MHz, 9-28V/m,
80% AM(1kHz) pulse mode
and other modulation
NOTE 1: UT is the a.c. mains voltage prior to the application of the test level
NOTE 2: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people
NOTE 4:The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz
to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
The amateur radio bandsbetween 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz,
5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz,10.1 MHz to 10.15 MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17
MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0
MHz.
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 device is used exceeds the applicable RF compliance level above, the device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

10V/m
Recommended separation distance
d=
d=0.6
d=1.2
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 less than the compliance
level in each frequency ranged.
Interference may occur in the
vicinity of equipment marked with
the following symbol:

80MHz to 800MHz
800 MHz to 2.7G Hz
