80MHz～2.7GHz
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,
a
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.
Note 3: The device that intentionally receives RF electromagnetic energy at the exclusion band
(2400-2483.5MHz) is exempt from the ESSENTIAL PERFORMANCE requirements, but remains
safe.
a
Field strengths from fixed RF 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 monitor is used exceeds the
applicable RF compliance level above, the monitor should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the monitor.
b
Over the frequency range 0.15 MHz to 80 MHz, field strengths should be less than 3 V/m.
