Recommended separation distances between portable and mobile RF communications equipment
and the HotDog Patient Warming System
The HotDog
TM
Patient Warming System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the HotDog Patient Warming System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the HotDog Patient Warming System 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
metres (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.
