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

Field strengths from fixed RF

electromagnetic site survey

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 device is used exceeds the applicable RF
compliance level above 3V/m., the device should be observed to verify normal operation. If
