Note 1 At 80MHz and 800MHz, 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.

should be used no closer to any
part of the 1133 Digital Blood
Pressure Monitor Equipment,
including cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
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).
b
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
c
should be less than the compliance
level in each frequency range.
d
Interference may occur in the
vicinity of equipment marked with
