RX/TX/WX LED INDICATOR. When your radio is in the CB receive mode, the LED will be green. When in transmit mode, the LED will be red and in Weatherband mode, the LED will be orange.
LED CHANNEL DISPLAY. The selected channel will be displayed. Display will be off when radio is in Weatherband mode.

Operation (Cont.)
14. CH.19/CH.9/NORMAL SWITCH. Used for instant selection of emer- gency Channel 9 (CH. 9 position) or information Channel 19. In NOR- MAL position, all 40 CB channels are selected by the CHANNEL SELEC- TOR switch (9).
15. S-METER.Swings proportionally to the strength of the incoming signal during receiving. The S/RF-SWR-CAL switch must be in the S/RF position.
RF-METER.Swings proportionally to the RF output power while trans- mitting. The S/RF-SWR-CAL switch must be in the S/RF position.
SWR METER. Measures standing wave ratio of the antenna system. Used to properly adjust the length of the antenna and to monitor the quality of the coaxial cable and all RF electrical connections. If there is any degradation whatsoever in any of the foregoing, due to humidity, salt spray, vibration or corrosion, the SWR meter reading will rise, thereby indicating that a problem exists.
To calibrate, switch to the "CAL" position, transmit by pressing the mike switch, and adjust the SWR control to the "CAL" mark on the meter; then switch to "SWR" position for the SWR measurement.

18. SOUNDTRACKER™ SWITCH. Depressing this button turns on the SoundTracker system in your CB.

19. SOUNDTRACKER™ INDICATOR. A red LED will illuminate when the SoundTracker system is engaged on your CB.

B. PRESS-TO-TALK MICROPHONE. Both the receiver and transmitter are controlled by the Press-to-Talk switch on the microphone. Press the switch and the transmitter is activated; release the switch to receive. When transmitting, hold the microphone two inches from the mouth and speak clearly in a nor- mal voice. The microphone provided with your radio is a detachable low- impedance dynamic type. The radio will not transmit in the Weatherband mode even though pressing the microphone switch will cause the red TX LED to illuminate.

1. PUBLIC ADDRESS: An external 8-ohm 4.0 watt PA speaker may be connect- ed 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.

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 inter- nal speaker is automatically disconnected.

3. ANTENNA CONNECTOR: This SO-239 connector permits connection of the transmission line cable PL-259 connector to the transceiver.

4. POWER. This jack permits connection of the DC power to the transceiver. A power cord with polarized plug is supplied with the radio. The polarized plug ensures that the power will always be connected properly.

Operating Procedure to Receive CB Broadcasts

1. Be sure that the power cord, antenna and microphone are connected to the proper connectors before proceeding further. The PA/CB should be in the CB position.

2. Turn the radio ON by rotating the VOLUME CONTROL clockwise.

3. Set the RF GAIN CONTROL fully clockwise.

4. Rotate SQUELCH CONTROL counterclockwise until incoming signal is heard.

5. Set the Channel Selector Switch to the desired channel.

6. Set VOLUME CONTROL to a comfortable listening level.

7. Engage the SoundTracker system by depressing the buttons labeled ST. SoundTracker system allows you to reduce unwanted background noise (stat- ic) and increase the signal for better reception.

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 receiv- er 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.
