The Telex HTU is a Hand Held Transmitter operating within the UHF FCC Part 74H frequency range. The transmitter is especially suited for use Wherever a small, reliable wireless microphone is required.

The Telex HTU Series features single channel crystal controlled units for the ultimate stability and clarity as well as economy. SETUP: Before setting up the transmitter, it is necessary to set up the receiver or at least check the receiver operation if the receiver has been installed previously. Place the receiver in an area with the antennas in clear View of the transmitter operating area. Connect the receiver audio output to the audio input of the mixer, amplifier or other device. Turn the input to these items down at this point. Apply power to the receiver. Note that there should be no "Carrier” or TX light on at the receiver at this time. If there is a light on. this indicates RF interference to the channel and the interference must be eliminated or you should consider Changing the channel frequency. If the interference is not severe, suitable operation can sometimes be made possible by adjusting the squelch control until the light goes off. Telex HTU Owners Continued. .
