Recommended Separation Distance Between Portable and Mobile RF
communication equipment and the Equipment or Systems
For all equipment and Systems that are not Life-Supporting -- Recommended separation distances
between portable and mobile RF communications equipment and Pulse Oximeter
The Pulse Oximeter is intended for use in electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Pulse Oximeter can help prevent electromagnetic intereference by
maintaining a minimum distance between portable and recommended below, according to the maximum out-
put power of the communications equipment.
Rated maximum Output
power of transmitter (W) Separation distance according to frequency of transmitter (m)
For transmitters rated at a maximum output power not listed above, the recommended separtaion 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.

The customer or the user of the PULSE OXIMETER should assure that it is used in such an environment.
Electronic
Environment Guidance
Portable and mobile RF communications equipment should not
be used close to any part of the Pulse Oximeter, including cables.
The recommended separation distance should be calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance
80MHZ to 800MHZ
800MHZ to 2.5GHz
Where P is maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and (d) is
the recommended separation distance in meters (m).
Where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey. should be less than the compliance
level in each frequency range.
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 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/FM radio, and TV broadcasts cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If measured field strength in the
location in which the Pulse Oximeter should be observed to verify normal operation. If abnormal performance is observed, ad-
ditional measurements may be necessary, such as reorienting the location of the Pulse Oximeter.
B.Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
