The warmer is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The user of the warmer can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
the warmer 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 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. These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
