Recommended separation distances between
portable and mobile RF communications equipment
and the WF-1000 Thermometer
The WF-1000 Thermometer is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
WF-1000 Thermometer can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmit-
ters) and the WF-1000 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 transmit-
ter in watts (W) according to the transmitter manufacturer.
NOTE 1
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and refl ection from structures, objects and people.
