Recommended separation distance between portable and mobile RF
he
The thermometer are intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customers or the users of these
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 ouptut 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 80MHz and 800MHz, the separation distance for the higher frequency
range applies
Note: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects, and people.
