At 80 MHz and 800 MHz, the higher frequency range applies. These guidelines might not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and people.

The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to
13.567 MHz and 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz are intended to decrease the likelihood that
mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 is used in calculating the recommended separation distance for transmitters in these frequency ranges.
strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which
the Efficia DFM100 is used exceeds the applicable RF compliance level above, the Efficia DFM100 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Efficia
d
DFM100.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic Environment - Guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the Efficia
DFM100 including cables, than the recommended
separation distance calculated from the equation applicable
to the frequency of the transmitter.
