Portable and mobile RF communications
equipment should be used no closer to
any part of the model VUN-001, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d=[3,5/V1]×P
d=1,2×P
80 MHz to 800 MHz
d=2,3×P
800 MHz to 2.7 GHz
where P is the maximum output power
rating of the transmitter In watts (W)
according to the transmitter manufacturer
and d Is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the compli-
ance level in each frequency range.
Interference may occur In the vicinity of
equipment marked with the following
symbol:
NOTE 1: At 80 MHz and 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.
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 VUN-001 is
used exceeds the applicable RF compliance level above, the model VUN-001 should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the model VUN-001.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
