B. Rear Panel
1. ANTENNA CONNECTOR: This SO-239 connector permits
connection of the transmission line cable male connector to the
transceiver.
2. PUBLIC ADDRESS: An external 8-ohm 4.0 watt PA speaker may be
connected to the PA Speaker Jack when this unit is used as a public
address system. The speaker should be directed away from the
microphone to prevent acoustic feed-back. Physical separation or
isolation of the microphone and speaker must be employed when
operating the PA at high output levels.
3. 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 disconnected.
4. POWER: These wires supply power to the CB radio. See page 5 for
installation.

Operation (Cont.)
Operating Procedure to Receive
1. Be sure that the power, antenna and microphone are properly
connected before proceeding further. The CB/PA switch should be
in the CB mode. The Channel 9/NOR Switch should be in the
NOR mode.
2. Turn the radio ON by rotating the VOLUME CONTROL
clockwise.
3. Rotate SQUELCH CONTROL counterclockwise until incoming
signal is heard.
4. Turn the CHANNEL SELECTOR KNOB to select the desired
operating channel.
5. Set the VOLUME CONTROL to a comfortable listening level.
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.
Operating Procedure to Transmit
1. Select the desired channel.
2. Press-to-Talk Switch. 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 microphone two inches
from the mouth and speak in a clearly 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.
Operating Procedure for Public Address
1. Connect a PA speaker to the PA jack provided on the rear panel.
2. Set the CB/PA switch to the PA position.
3. Depress the push-to-talk switch on the microphone and speak in a
normal voice.
4. Adjust the volume of the PA speaker using the Volume control on
the front panel.
