Portable and mobile RF communications
equipment should be used no closer to
any part of the VX36, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter. Recommended separation
distance
d=1.2xP1/2
d=1.2xP1/2 80 MHz to 800 MHz
d=2.3xP1/2 800 MHz to 2,5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the manufacturer and d is
the recommended separation distance
in meters (m). Field strengths from fixed
RF transmitters, as determined by an
electromagnetic site surveya, should be
less than the compliance level in each
frequency rangeb. 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 solutions. Electromagnetic propagation is affected by absorption and reflection form 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
VX36 is used exceeds the applicable RF compliance level above, the VX36 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the VX36.
b Over the frequency range 150 kHz à 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
VX36
The VX36 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the VX36 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the VX36 as recommended below, according to the maximum output power of the
communications equipment.
