OPERATION

2.0 INTRODUCTION
This section explains the basic operating procedures for the DX 929 mobile CB radio.
2.1 CONTROLS AND CONNECTIONS
2.1.1 FRONT PANEL
Refer to the above Figure 2-1 for the location of the following controls.
1. MICROPHONE JACK: Used to connect microphone for voice source.
2. SQUELCH CONTROL: This knob is used to eliminate background noise being heard through the
receiver, which can be disturbing when no transmissions are being heard through the receiver. To
use this feature, turn the knob fully counterclockwise and then turn clockwise slowly until the
background noise is just eliminated. Further clockwise rotation will increase the threshold level
which a signal must overcome in order to be heard. Only strong signals will be heard at a maximum
clockwise setting.
3. ON/OFF VOLUME CONTROL: This knob controls the volume and power to the radio. To turn
radio on, rotate the knob clockwise. Turning the knob further will increase the volume of the
receiver.
