the antenna cable end.

8-16 ohms. Connecting the earphone or speaker plug into this jack automatically silences the
built-in speaker.

This selects mode of operation; Lower Sideband (LSB), Upper Sideband (USB) and AM.
OPERATION
MAKE SURE YOUR ANTENNA SYSTEM IS CONNECTED TO THE ANTENNA CONNECTOR
ON THE REAR PANEL. DO NOT OPERATE THE TRANSCEIVER WITHOUT CONNECTION
OF YOUR ANTENNA SYSTEM.
A. AM Operation
1. Connect the Push-to-Talk microphone to the MIC jack
•
2. Place the CB/PA switch in the "CB" position.
3. Turn the power on and increase the sound level.
4. If necessary, adjust the SQUELCH control.
5. Place the LSB-USB-AM switch in the AM position.
6. Select a channel you desire.
7. To transmit: Depress the Push-to-Talk button on the microphone and speak into the
microphone at a normal voice, holding the microphone 3 to 6 inches from the mouth.
Do not shout or move the microphone too close to your mouth.
8. To receive: simply release the Push-to-Talk button.
9. If necessary, adjust the CLARIFIER control and ANL/NB switch for clearer reception.
B. SSB Reception
1. Turn the power on and rotate the VOLUME control to a proper sound level.
2.
Temporarily place the LSB-USB-AM switch in the AM position. If the signal you received
is a AM signal, clear voice reception will be obtained. But if the signal produces un-

LSB or USB position, where clearer voice reception is obtained. Then adjust the
CLARIFIER control slowly for better voice reception.
3. If necessary adjust SQUELCH and ANL/NB control.
