Recommended Separation Distances Between Portable and Mobile
RF communications equipment and the "Phasor™ Heated Composite
Delivery System"
The Phasor™ heated composite delivery system is intended for use in the
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Phasor™ heated composite delivery system can
help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
Phasor™ heated composite delivery system as recommended below, according to the
maximum output power of the communication equipment.

Table: According to IEC 60601-1-2, Edition 4.0
For transmitters rated at a maximum output power not listed above,
the recommended separation distance d in meters (m) can be determined
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: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
