GUIDANCE AND MANUFACTURE'S DECLARATION-ELECTROMAGNETIC IMMUNITY
FOR EQUIPMENT AND SYSTEMS THAT ARE NOT LIFE-SUPPORTING
Guidance and manufacture's declaration-electromagnetic immunity
The Pulse Oximeter is tended for use in the electromagnetic environment specified below. The user of
the Pulse Oximeter should assure that it is used in such an environment.

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 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 11-50DP Pulse Oximeter is used exceeds the applicable RF compliance
level above, the 11-50DP 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
11-50DP Pulse Oximeter.

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

the transmitter manufacturer and d is the
recommended separation distance in meters (m).
