portable and mobile RF communications equipment and the VRA201.
The VRA201 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the VRA201 can help prevent electromagnetic interferences by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the VRA201 as recommended below, according to the maximum output power of the
communications equipment.

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

covered with synthetic material,
the relative humidity should be
greater than 30%.
Mains power quality should be

recommended that the VRA201
be powered from an
uninterruptable power supply or
its battery.
