  • Page 2: General Information

    GENERAL INFORMATION The Telex Model UR-700 Receiver and associated Transmitters is a full diversity system operating within the frequency range of 690 to 725 MHz on specific pre-set frequencies. Systems consisting of the UR-700 and its companion transmitter are capable of operating on at least 5 frequencies in a TV channel simultaneously, sometimes more depending on the individual venue.
  • Page 3 The line output level is adjustable with a screwdriver accessible potentiometer. Power The UR-700 will operate from the supplied AC adapter or any nominal 12-15 volt AC/DC 300 mA supply. Audio The UR-700 audio circuitry is designed to complement the transmit- ter audio.

RF Display: A 1-segment LED Display indicates the presence of the signal from the transmitter. Diversity Display: LED’s indicate diversity operation. AF Display: A 5-segment 3 color LED Display indicates the relative modulation of the microphone.

  • Page 12 Set-Up NOTE: Do not use carbon-zinc batteries. 8.4 volt Ni-Cad batteries may be used but will yield shorter run times. Open the battery door and install a 9 volt alkaline battery. Be sure the battery polarity matches the diagram inside the battery holder. Close the battery door.
  • Page 13 Antenna Placement The antennas and UR-700 should be placed in a location with a clear “signal path” to the transmitter. This “path” should be as short and free of obstructions as possible. Obstructions, such as walls, ceilings, and metal objects, will reduce range and performance.
  • Page 14 The diversity antenna system operates most efficiently when the two antennas are separated as much as possible. The antennas should be mounted so that they are at least 6 feet (2 meters) apart for best results. They should be at least 2 feet (60 cm) from nearby objects.
  • Page 15 If possible, do not mount the brackets on a wall. See Figure 7 for bracket and antenna placement. Antenna Connection Attach the two antenna cables to the back of the UR-700. Be sure the connectors are tightened securely. Route the cable to the antennas and attach in the same manner.
  • Page 16 Installing Rack Mounts The UR-700 is supplied with rack mounts for both double and single mounting in a 19" equipment rack. For single mounting, the long and short rack “ears” are used. For dual mounting, use the short “ears and the mid brackets from two UR-700’s.
  • Page 17 Double Mounting: Align the mid brackets (Item No. 2) with the holes on the adjacent sides of each unit. Install the previously removed screws. Insert an additional screw (Item No. 4 provided in the parts pack) into the remaining holes. Tighten all screws securely.
