Recommended separation distance between Portable and mobile RF
communications equipment and HemoCue

Hb 301 Analyzer
The HemoCue systems are intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled.
The customer or the user of HemoCue systems can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and RF communications equipment (transmitters) and
HemoCue systems as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at maximum output power not listed above, the
recommended separation distances (d) in meters (m) can be estimated
using the equation applicable to the frequency of the transmitter,
where (P) is the maximum output power rating of the transmitter in
watts (W) according to transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the
higher frequencyrange applies.
NOTE 2 These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
