Portable and mobile RF
communications equipment should be
used no closer to any part of the
Atomlab 960 Thyroid Uptake System,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter. Recommended
separation distance:
d = 1.2√ P 150 KHz to 80 MHz
d = 1.2√ P 80 MHz to 800 MHz
d = 2.3√ P 800 MHz to 2.5 GHz
Where P is the maximum output power
rating of the transmitter in watt (W)
according to the transmitter
manufacturer, and d is the
recommended separation distance in
meters (m). Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should
be less than the compliance level in
each frequency range.
b
Interference
may occur in the vicinity of equipment
marked with the following symbol:
Note 1. UT is the AC mains voltage prior to application of the test level.
Note 2. At 80 MHz and 800 MHz, the higher frequency range applies.
Note 3. These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflections from structures, objects and people
a
Field strength from mixed transmitters, such as base stations for radio telephones and land mobile radios,
amateur radio, AM or FM 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 Atomlab 960 Thyroid Uptake System is used exceeds the
applicable RF compliance levels above, the Atomlab 960 Thyroid Uptake System should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the
Atomlab
960 Thyroid Uptake System.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
