Recommended Separation Distance Between Portable and Mobile
RF Communications Equipment and the Thermometer
The thermometer is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customers or users of this
thermometer can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the thermometer 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 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
the transmitter manufacturer.
Note: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies
Note: These guidelines may not be applicable in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
