Recommended separation distances between
portable and mobile RF communications instrument and KOWA nonmyd WX
KOWA nonmyd WX is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The cus-
tomer or the user of KOWA nonmyd WX can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications instrument (transmitters) and KOWA nonmyd WX as recommended below, according to the
maximum output power of the communications instrument.
