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" position.
2 . Turn the radio ON by rotating the VOLUME CONTROL 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 CON-
TROL 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 transmit-
ting. Prolonged transmitting without an antenna,or a poorly matched
antenna, could cause damage to the transmitter.
