situation for radio
(cellular/cordless) telephones
and land mobile radios, amateur
radio, AM and FM radio
broadcast and TV broadcast
cannot 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 Handheld
Pulse Oximeter is used exceeds
the applicable RF compliance
level above, the Handheld Pulse
Oximeter should be observed.
Recommended separation distances
between portable and mobile RF
communications equipment and the
Handheld Pulse Oximeter
The Handheld Pulse Oximeter is
intended for use in an electromagnetic
environment in which radiated RF
disturbance are controlled. The
customer or the user of the Handheld
Pulse Oximeter can help prevent
electromagnetic interference by
maintaining a minimum distance
between portable and mobile RF
communication equipment
( transmitters) and the Handheld 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 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.
NOTE1 At 80MHz and 800MHz, the
separation distance for the higher
frequency range applies.
NOTE2 These guidelines may not
apply in all situations. Electromagnetic
interference is affected by absorption
and reflection from structures, objects
and people.
