Field strengths from fixed 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 1 At 80 MHz - 800 MHz, 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.
A) Field strengths from fixed 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 fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the model PT X is used exceeds the applicable RF compliance level above, the model PT X
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the model PT X.
B) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between
portable and mobile RF communications equipment and the model PT X
The model PT X is intended for use in electromagnetic environment in which radiated RF disturbances is controlled. The customer or
the user of the model PT X can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the model PT X is recommended below, according to the maximum output
power of the
communications equipment.
