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 150 kHz
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.
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
theNAVI-30/NAVI-60 vein illuminator is used exceeds the applicable
RF compliance level above, theNAVI-30/NAVI-60 vein illuminator
should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as re-orienting
or relocating theNAVI-30/NAVI-60 vein illuminator.
d
Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than [3] V/m
