Guidance and manufacturer’s declaration – electromagnetic immunity
The ME 211 is intended for use in the electromagnetic environment specified
below. The customer or the user of the ME 211 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
ME 211, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of the
transmitter.
Recommended separation distance
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:
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 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 ME 211 is used exceeds the applicable
RF compliance level above, the ME 211 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the ME 211.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
