Table 13. 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 ensure that it is used in such an environment.

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,

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: Ut is the AC mains voltage prior to application of the test level.
At 80MHz and 800MHz, the higher frequency range applies.
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 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 re‑orienting or relocating the system.
b. Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
