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.
a The ISM (industrial, scientific and medical) bands between 0,15 MHz
and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz;
26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur
radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz,
3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz
to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHZ, 21,0
MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and
50,0 MHz to 54,0 MHz.
b The compliance levels in the ISM frequency bands between
150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7
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 has been incorporated into the formulae
used in calculating the recommended separation distance for
transmitters in these frequency ranges.
c 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 Model
PG-IRT1603
Infrared Thermometer is
used exceeds the applicable RF compliance level above, the Model
PG-IRT1603
Infrared Thermometer should be observed to verify
normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the
Model
PG-IRT1603
Infrared Thermometer.
d Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.
