The LCP-7800 is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the LCP-7800 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
( transmitters ) and the LCP-7800 as recommended below, according to the maximum output power of
the communications equipment.
