TECHNICAL INFORMATION

TR-34 RECEIVER

General Description TR-34

The Telex TR-34 Receiver is a component of
a system which operates on 16 selectable
channels in the 60-72 MHz frequency band.
The receivers are designed to be used with the
Telex TT-44 Transmitter.

Operating Features

Volume OFF/ON Control:

This thumbwheel

control serves as both an off/on switch and as
a volume control. The receiver is turned off
when the control is in the extreme coun-
ter-clockwise position, when viewed from the
front, and the volume is loudest when the con-
trol is in the extreme clockwise position as in-
dicated on the volume control.

NOTE:

The Headphone Jack must have a

headphone, or other accessory, plugged in
to activate the TR-34 power “ON”. Power
“ON” is indicated by the lighting of the
channel numbers.

Headphone Jack

The headphone jack accepts a 0.140-inch (3.5
mm) diameter miniature mono or stereo phone
plug. A variety of accessory units can be
plugged into this jack for reception of the de-
sired channel(s) being transmitted.

Treble Control

A push button treble control is provided to en-
hance the “high” audio when the button is en-
gaged, indicated by

, the “High” audio is

emphasized.

Belt Clip

The belt clip supplied is detachable by spread-
ing the wire apart at the tops and removing
one side of the clip from the case and then the
other.
