IMMUNITY
• P= Manufacturer's output power in watts (W).
• d= Recommended distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
be less than the compliance level in each frequency
range.
CAUTION: Interference may occur in the vicinity of
equipment marked with the following symbol:
Note: At 80 MHz and 800 MHz, the higher frequency range
applies.
Note: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people
a
F ield strengths from fixed RF 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 Digit ® pulse oximeter is used exceeds the applicable
RF transmitter compliance level above, the Digit ® 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 Digit ® pulse
oximeter.
