Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Welch Allyn Home Blood Pressure
Monitor, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d= 1,2
d= 1,2 80 to 800 MHz
d= 1,2 800 MHz to 2,5 GHz
d= 2,3 800 MHz to 2,6 GHz
whereP is the maximum output power rating of
the transmitter in watts (W) andd is the
recommended separation distance in meters
(m).
