HemoCue WBC DIFF Operating Manual page 77

Recommended separation distance between Portable and
mobile RF communications equipment and HemoCue WBC
DIFF 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 (transmit-
ters) 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.
