tic site survey should be considered. If the measured field strength in the location in which the TL90 is used

exceeds the applicable RF compliance level above, the Medical Daylight should be observed to verify normal

operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting

or relocating the TL90.

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.
