Telex Model SAFE-1000 UHF Wireless Microphone Receiver The Telex Model SAFE-1000 Receiver is a 950 Channel, frequency-selectable full diversity system operating within the frequency range of 520.0 to 608 and 614 to 746.0 MHz, on specific pre-set bands of frequencies with designated systems for UHF Television Channels . distance away from the area where the FMR-1000 is to be used, Channel spacing has been computer calculated and programmed to minimize receiver interference. Systems of SAFE-1000 and its companion transmitters are capable of operating on at least 5 sets of frequencies in a single TV channel simultaneously, sometimes more depending on the individual venue. Certain frequencies can be combined to form a system of 16. Digital frequency control of the SAFE-1000 permits flexibility within a given area and assures confidence in the equipment capability.
