Test level
MESI mTABLET ABI is intended for use in the electromagnetic environment specified below. The customer or the user of the
above listed models should assure that they are used in such an environment.
a)
Field strengths from fixed transmitters such as base stations for radio (cellular/cordless) telephones, 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 MESI mTABLET ABI is used, exceeds the applicable RF compliance level above, the above
listed models should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the above listed models.
b)
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
c)
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 bands between 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 24.99 MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0
MHz.

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:
NOTE 1 At 80 MHz and 800 MHz, 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.
