5. Recommended separation distances between portable and mobile RF
communications equipment and the medical monitor
The medical monitor is intended for use in the electromagnetic environment in which the RF disturbances
are controlled. The user of the device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the
device – as a function of the output power of the communication device, as shown below.

For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance
d
in meters (m) can be estimated using 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.
