Controls and Functions

Uniden Grant LT AM/SSB CB Radio


1. Microphone Jack

2. OFF/VOL: Turns radio on or off; adjusts speaker volume.

3. SQUELCH: Reduces background noise when there is no incoming signal.

4. RF GAIN: Improves reception in strong signal areas.

5. MIC GAIN Adjusts microphone sensitivity.

6. S/RF CAL SWR Knob: Selects function of meter.

7. LSB AMUSB Knob: Selects mode.

8. CLARIFIER Knob: Fine tunes the SSB receiving signals.

9. SWR Knob: Calibrates the meter for Standing Wave Radio (SWR) measurements.

10. Channel Knob: Selects channel.

11. Multi-function Meter: Measures SWR, RF and S signal strength.

12. NB/ANL Switch: Reduces external noise and interference from vehicle ignition systems.

13. CB/PA Switch: Selects PA optional (Public Address) speaker or CB.

Do not use PA function unless an external speaker is connected.

14. HI/LOW Switch: Hi position increases treble, Low position increases bass.

15. BRT/DIMSwitch: Adjusts the brightness of LED Channel Display and meter lighting.

16. DYNAMIC SQUELCH CONTROL (DSC): Automatically sets squelch to optimal level for stronger signals.

17. RX/TXIndicator: Red transmitting; green receiving.

When the external speaker is plugged in, the internal speaker is off.

21. EXT. SP.: Connects optional 8-ohm 4-watt speaker to remotely monitor receiver.

22. POWER: Connects DC power to transceiver.
