Recommended separation distances between
portable and mobile RF communications equipment and the model CL-S500
The model CL-S50 0 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the model CL-S500 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the model CL-S500 as recommended below,
according to the maximum output power of the communications equipment.
Immunity to proximity elds from following RF wireless communication equipment has been
