Portable and mobile RF
communications equipment should be
used no closer to any part of the
12-channel electrocardiograph,
including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
Pd 2.1
Pd 2.1 80 MHz to 800 MHz
Pd 3.2 800 MHz to 2.5 GHz
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
metres (m).
