Portable and mobile RF
communications equipment should
be used no closer to any part of the
Efficia CM patient monitors, including
cables, than the recommended
separation distance calculated from
the equation applicable to the
frequency of the transmitter.

where P is the maximum output
power rating of the transmitter in
watts (W) according to the transmitter
manufacturer and d is the
recommended separation distance in
meters (m).

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mo-
bile 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 Efficia CM patient monitor is used
exceeds the applicable RF compliance level above, the Efficia CM patient monitor should be observed to verify
normal operation. If abnormal performance is observed, additional measures are necessary, such as re-orienting
or relocating the monitor.
b
Signal levels above 1V/m in the 1215 – 1240 MHz band may disrupt wireless communications from the Efficia CM
Patient Monitor if the operating channel in the 2.4 GHz band is at twice the frequency.
