Recommended separation distances between portable and mobile RF
communications equipment and the Arctic Sun™ Temperature Management
System unit
RF communications equipment can affect medical electrical equipment. The Arctic
Sun™ Temperature Management System unit is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Arctic Sun™ Temperature Management System unit
can help prevent electromagnetic interference by maintaining a minimum distance
between the portable and mobile RF communications equipment (transmitters) and
the Arctic Sun™ Temperature Management System unit 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 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.
