Recommended separation distances between
portable and mobile RF communications equipment and the CMS50DA
Pulse Oximeter
The CMS50DA Pulse Oximeter is intended for use in the electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the CMS50DA Pulse Oximeter can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the CMS50DA 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 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
propagation is affected by absorption and reflection from structures, objects and
people.

the transmitter manufacturer and d is the
recommended separation distance in meters

determined by an electromagnetic site survey,

Interference may occur in the vicinity of
equipment marked with the following symbol:
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.
a. Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcastcannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If
the measured field strength in the location in which The CMS50DA Pulse
Oximeter is used exceeds the applicable RF compliance level above, the
CMS50DA 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 CMS50DA Pulse Oximeter.
b. Over the frequency range 150 KHz to 80 MHz, field strengths should be
less than 3V/m.
