Guidance and manufacturer’s declaration – electromagnetic immunity
The ME80 is intended for use in the electromagnetic environment specified below. The customer or the user
of the ME80 should assure that it is used in such an environment.

Portable and mobile RF communications equipment should
be used no closer to any part of the ME80, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
Where P is the maximum output power rating of the trans-
mitter 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 com-
pliance 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.
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 theoreti-
cally with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electroma-
gnetic site survey should be considered. If the measured field strength in the location in which the ME80 is
used exceeds the applicable RF compliance level above, the ME80 should be observed to verify normal ope-
ration. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the ME80.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
