Recommended separation distances between

portable and mobile RF communications equipment and the TL90

The TL90 is intended for use in an electromagnetic environment in which radiated RF disturbances are con-

trolled. The customer or the user of the Medical Daylight can help prevent electromagnetic interference by

maintainingaminimumdistancebetweenportableandmobileRFcommunicationsequipment(transmitters)

and the TL90 as recommended below, according to the maximum output power of the communications

equipment.
