Recommended separation distances between portable and mobile RF communications
equipment and the Thermometer
The monitor is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
as recommended below, according to the maximum output power of
the communications equipment.

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