Guidance and manufacturer's declaration - electromagnetic immunity
The 200-series devices are intended for use in the electromagnetic
environment specified below. The customer or the user of a 200-series device
should assure that it is used in such an environment.

NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
The 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 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 can be considered. If the
measured field strength in the location in which a 200-series device is used exceeds the
applicable RF compliance level above, the 200-series devices should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the 200-series device.
b Over the frequency range 150 kHz to 80 MHz, field strengths must be less than 10 V/m.

Portable and mobile RF
communications equipment should
be used no closer to any part of a
200-series device, including cables,
than the recommended separation
distance calculated from the
equation applicable to the frequency
of the transmitter.

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 metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey
be less than the compliance level in
each frequency range
