Guidance and manufacturer's declaration – electromagnetic immunity
The Fingertip Oximeter is intended for use in the electromagnetic environment specified below.
The customer or the user of the Fingertip Oximeter should assure that it is used in such an
electromagnetic environment.

NOTE 1 At 80 MHz and 800 MHz, 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 Fingertip Oximeter
is used exceeds themapplicable RF compliance level above, the Fingertip Oximeter should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
