Recommended separation distances between

models WL1 and WL3

The models WL1 and WL3 are intended for use in

electromagnetic environment in which radiated RF disturbances

is controlled. The customer or the user of the models WL1

and WL3 can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile

RFcommunicationsequipment(transmitters)andthemodels

WL1 and WL3 as recommended below, according to the
