guidance
Portable and mobile RF com-
munications equipment should
be used no closer to any part of
The Fingertip Oximeter, including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the transmitter.
Recommended separation
distance
d= 1.2 √P
d= 1.2 √P
80MHz to 800MHz
d= 2.3 √P
800MHz to 2.5GHz
Where P is the maximum output
power rating of the transmitter in
watts (W) according to the trans-
mitter manufacturer and d is the
recommended
tance in metres (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
should be less than the com-
pliance level in each frequency
range.
