Compliance
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 environ-
ment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in
which the BiPAP Focus System is used exceeds the applicable RF
compliance level above, the BiPAP Focus System should be observed
to verify normal operation. If abnormal performance is observed, addi-
tional measures may be necessary, such as reorienting or relocating
the BiPAP Focus System.
b. Over the frequency range 150kHz to 80MHz, field strengths should be
less than 3 V/m.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
