NOTE 1
U is the a.c. mains voltage prior to application of the test level.
NOTE 2
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 3
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
a)
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 HemoCue systems are
used exceeds the applicable RF compliance level above, the HemoCue systems should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the systems.
b) Over the frequency range 150 KHz to 80 MHz, field strength should be less than 3 V/m.
