Ranger RCI-6300F TB, RCI-6300F HP Operation Procedure to Receive, Procedure to Transmit

2.3 OPERATION

2.3.1 PROCEDURE TO RECEIVE

1.Be sure that power source, microphone and antenna are connected to the proper connectors before going to the next step.

2.Turn unit on by turning VOL knob clockwise on transceiver.

3.Set the VOL to a comfortable listening level.

4.Set the MODE switch to the desired mode.

5.Listen to the background noise from the speaker. Turn the SQ knob slowly clockwise until the noise just disappears. The SQ is now properly adjusted. The receiver will remain quiet until a signal is actually received. Do not advance the control too far or some of weaker signals will not be heard.

6.Set the CHANNEL selector switch to the desired channel.

7.Set the RF GAIN control fully clockwise for maximum RF gain.

2.3.2 PROCEDURE TO TRANSMIT

1.Select the desired channel of transmission

2.Set the MIC GAIN control fully clockwise.

3.If the channel is clear, press the push-to-talk switch on the microphone and speak in a normal voice.

2.4 ALTERNATE MICROPHONES AND INSTALLATION

For best results, the user should select a low impedance dynamic type microphone or a transistorized microphone. Transistorized type microphones have a low output impedance characteristic. The microphones must be provided with a four-lead cable. The audio conductor and its shielded lead comprise two of the leads. The third lead is for transmit control and the fourth is for receiving control. The microphone should provide the functions shown in schematic below (Figure 2-3).
