Recommended Separation Distances Between the Device and Portable and
The ScanX is intended for use in an electromagnetic environment in which radiated RF interferences
are controlled. The user of the ScanX can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the
ScanX such 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 established by 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 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, ob-
jects and people.
