Guidance and 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.

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.

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).

3 V/m 80MHz to

Note: At 80 MHz and 800 MHz, the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
Note: The TMS that intentionally receives RF electromagnetic energy at the exclusion band (2395.825MHz-
2487.645MHz) is exempt from the ESSENTIAL PERFORMANCE requirements, but remains safe.
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 reorienting or relocating
the system.
b: Over the frequency ranges 150kHz to 80MHz, field strengths should be less than 3V/m.
