Recommend separation distance
The following list 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 RF transmitters as determined by an electromagnetic site
survey,*2) should be less than the compliance level in each frequency range.*3)
Interference may occur in the vicinity of equipment marked following symbol:

Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects, and people.
*2) Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless)telephones and land mobile 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 vital sign monitor is
used exceeds the applicable RF compliance level above, the vital sign monitor should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the .
*3) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
