B-14 appendix b
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 transmit-
ters, consider conducting an electromagnetic site survey. If the measured field
strength in the location in which the CDI System 550 is used exceeds the
applicable RF compliance level above, observe the CDI System 550 to verify
normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the CDI System 550.
b Over the frequency range 150 kHz to 80 MHz, field strengths shall not
exceed 3 V/m.
Verify the accuracy of displayed values with another source (i.e. laboratory or
point of care blood gas analyzer) before initiating treatment if performance is
lost or degraded due to EM disturbances.
