For any maximum rated output power which is not listed in the table above,
the recommended distance d (in meter) can be determined based on the
formula in the corresponding volume of transmitter frequency, where p is
the maximum rated output power in (Watt) of transmitter provided by its
manufacturer.
Note 1：
For frequency of 80MHz and 800MHz, a formula in respect of high
frequency should be used.
Note 2：
ISM bands between 150kHz and 80MHz are 6.765MHz~6.795MHz,
13.553MHz~13.567MHz, 26.957MHz~27.283MHz and
40.66MHz~40.70MHz.
Note 3：
Additional factor 10/3 is used for calculation of recommended distance to
the transmitter within frequency ranges of 150kHz ~ 80MHz and
80MHz~2.5GHz, so as to reduce the possibility of interference resulted from
mobile/portable communication devices which are accidentally taken into
patient's location.
Note 4：
As EM transmission is affected by absorption and reflection of buildings,
objects and human bodies, these guidelines may not be applicable to all
circumstances.
