portable and mobile RF communications equipment and the Aquatherm III Heater.
The Aquatherm III Heater is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled . The customer or the user of the Aquatherm III Heater can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the
Aquatherm III Heater as recommended below, according to the maximum output 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 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
reflection from structures, objects and people.
