B. Rear Panel
1. Antenna Connector. This female connector permits
connection of the transmission line cable male connec-
tor to the transceiver.
2. External Speaker. The External Speaker Jack is used
for remote receiver monitoring. The external speaker
should have 8-ohm impedance and be rated to handle
at least 4.0 watts. When the external speaker is
plugged in, the internal speaker is automatically dis-
connected.
3. Power: This cable is permanently attached to the radio.
If you wish to remove the radio after installation, dis-
connect at fuse holder and ground connector.
Operating Procedure to Receive
1. Be sure that power cord, antenna and microphone are
connected to the proper connectors before proceeding
further. The weather switch should be in the "CB" posi-
tion.
2. Turn the radio ON by rotating the VOLUME CON-
TROL clockwise.
3. Rotate SQUELCH CONTROL counterclockwise until
incoming signal is heard.
4. Select the desired channel.
5. Set VOLUME CONTROL to a comfortable listening
level.
6. Engage the SoundTracker system by depressing the
button labeled ST.
Listen to the background noise from the speaker. Turn the
SQUELCH CONTROL slowly clockwise until the noise JUST
disappears (no signal should be present). Leave the control at
this setting. The squelch 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 the weaker
signals will not be heard. The revolutionary SoundTracker
system allows you to reduce unwanted background noise
(static) and increase the signal for better reception.
Operating Procedure to Transmit
1. Select the desired channel.
2. The receiver and transmitter are controlled by the press-
to-talk switch on the microphone. Press the switch and
the transmitter is activated; release switch to receive.
When transmitting (on a clear channel), hold the micro-
phone two inches from the mouth and speak clearly in a
normal voice.
Be sure the antenna is properly connected to the radio
before transmitting. Prolonged transmitting without an
antenna, or a poorly matched antenna, could cause damage
to the transmitter.
