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

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the System, including cables, than the
recommended separation distance, calculated
from the equation applicable to the frequency
of the transmitter.

Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
a should be range. b
Interference may occur in the vicinity of equip-
ment 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans-
mitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the System is used exceeds the applicable RF compliance level above, the System
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as relocating the System.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
