Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may 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; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
Field 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 RESCUE SAM is used exceeds the applicable
RF compliance level above, the RESCUE SAM should be observed to verify normal operation. If abnormal
performance is observed additional measures may be necessary, such as reorienting or relocating the RESCUE
SAM.

Compliance Electromagnetic environment -
level
Power frequency magnetic fields should
not be greater than levels characteristic
of a typical location in a commercial or
hospital environment.
Portable and mobile RF
communications equipment should be
used no closer to any part of the
RESCUE SAM , including cables, than
necessary. The recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter is shown in the
following table.
