Recommended Isolation Distance between Portable and Mobile RF Communication Device and
the infusion pump
The infusion pump is expected to use in the electromagnetic environment where RF radiated
disturbance is under control. According to the maximum rated output power of communication device,
purchasers or users can prevent electromagnetic interference by maintaining the minimum distance
between portable and mobile RF communication device (transmitter) and the infusion pump.

For the Rated maximum output power of transmitter not listed in the table above, isolation distance
d
,
in m, is recommended. It can be determined with the formula in the frequency column of corresponding
transmitter.
P
here is the maximum rated output power of transmitter, in W, provided by transmitter
manufacturer.
Note 1: At 80 MHz and 800 MHz, the formula of higher frequency range applies.
Note 2: This guidance may not apply to all situations, electromagnetic propagation is affected by
the absorption and reflection of buildings, objects and human bodies.
