HemoCue WBC DIFF, Operating Manual, Page: 80 / 84

80
NOTE 1 U is the a.c. mains voltage prior to application of the test level.
NOTE 2 At 80MHz and 800MHz, 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 elec-
tromagnetic 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 neces-
sary, 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.
