the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from xed RF transmitters,
as determined by an electromagnetic site survey
(a), should be less than the compliance level in
each frequency range (b). Interference may occur
in the vicinity of equipment marked with the
following symbol:

NOTE: UT is the a.c. mains voltage prior to application of the test level.
NOTE: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is aected
by absorption and reection from structures, objects and people.
a - Field strengths from xed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and
TV broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to xed RF transmitters, an electromagnetic
site survey should be considered.
If the measured eld strength in the location in which the Phasor™ heated composite delivery
system is used exceeds the applicable RF compliance level above, the Phasor™ should
be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the Phasor™ heated composite
delivery system.
b - Over the frequency range 150 kHz to 80 MHz, eld strength should be less than 10 V/m.

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.

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 aected
