FERENCE Turn the control clockwise to reduce interference from noise and out side radio signals It is best to set the squelch with the transmitter turned off Turn the control counter clockwise until you hear noise or interference over your sound system Then turn it clockwise until the noise is squelched off This setting will give you your best interference free range Remember too much squelch will reduce range Turn on the microphone power switch When the power switch is turned on the battery light will flash one time if the battery is good If the light does not flash or stays lit continuously the battery is weak or dead If the light comes on during use the battery is weakening and should be replaced as soon as possible 11 The RF light on the receiver should now be illuminated Turn on the audio mic switch Speak into the microphone and adjust its gain so that the Audio Meter on the receiver just illuminates the 0 or yellow light on the loudest sounds If necessary vary the line level on the back of the receiver to suit your equipment Walk the transmitter through the expected use area to check for drop outs To minimize the chance for drop outs read the section on antenna placement 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 ceili

6. Telex Operating Instructions UR 700 UHF Wireless Microphone System TELEX 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 Certain frequencies can be combined to form a set of systems compatible for simultaneous use Posi Phase Diversity The UR 700 receiver utilizes Telex s patented Posi Phase auto diver sity circuit Unlike other types of diversity which receive with only one antenna at a time Posi Phase utilizes both antennas at all times This results in a stronger signal from the microphone for cleaner audio and greater range If the microphone signal begins to go out of phase a common cause of drop outs with other types of diversity the Posi Phase circuit adjusts the phase angle between the two antennas receiving circuits to prevent phase cancellation This action is indicated by the 0 and 180 degree diversity lights on the front panel Antennas There are two TNC type antenna connectors on the rear panel These connectors are superior to the more common BNC connectors both electrically and mechanically TNC connectors are becoming the standard due to their
