Guidance and manufacturer´s declaration – electromagnetic immunity
– for EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING
This device is intended for use in the electromagnetic environment specified below. The user of this device
should assure that it is used in such an environment.

Portable and mobile RF communications equipment should

Oximeter, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.

manufacturer and d is the recommended separation

Field strengths from fixed RF transmitters, as determined
by an electromagnetic site survey, a should be less than the
compliance level in each frequency range. b
Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic 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 A310 Fingertip Pulse Oximeter is used exceeds the applicable RF compliance level above, the A310
Fingertip 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 A310 Fingertip Pulse
Oximeter.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
