Recommended separation distances
The table below provides the recommended separation distances (in meters) between portable and mobile RF communications equipment and
the monitor.
The monitor is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the equipment can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the equipment 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 manufacture.
NOTE 1At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
