controlled. The customer or the user of the oximeter can
help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF
communications equipment (transmitters) and the oximeter s
recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed
above, the recommended separation distance d in metres (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 80 MHz and 800 MHz, the separation
distance for 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.
