environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If
the measured field strength in the location in which the Pulse Oximeter is used exceeds the
applicable RF compliance level above, the Pulse Oximeter should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Pulse Oximeter.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.

Recommended separation distances between
portable and mobile RF communications equipment and the Pulse Oximeter.
The Pulse Oximeter is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Pulse Oximeter can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Pulse Oximeter as 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 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 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.
