Recommended separation distances between portable and mobile
RF communications equipment and the SPO 55 Pulse Oximeter
For transmitters rated at a maximum output power not listed above, the recommended
separation distanced in meters (m) can be estimated using 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.
NOTE 1 At 80MHz and 800MHz, the separation distance for the higher frequency
range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propaga-
tion is affected by absorption and reflection from structures, objects and
people.
