Electromagnetic Environmental Recommendations<br />
Recommended separation distances between portable and mobile RF communications<br />
equipment and the EQUATOR ® Convective Warmer<br />
The convective warmer is intended for use in an electromagnetic environment in which radiated RF<br />
disturbances are controlled. The customer or the user of the convective warmer can help prevent<br />
electromagnetic interference by maintaining a minimum distance between portable and mobile RF<br />
communications equipment (transmitters) and the convective warmer as recommended below, according to<br />
the maximum output power of the communications equipment.<br />

For transmitters rated at a maximum output power not listed above, the recommended separation distance<br />
d in metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P<br />
is the maximum output power rating of the transmitter in watts (W) according to the transmitter<br />
manufacturer.<br />
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.<br />
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by<br />
absorption and reflection from structures, objects and people.<br />
