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.
