Feature Operation
1.4 Pin Microphone Connector
2.On/OFF Volume Knob- Turn clockwise to turn power on and set to the desired listening volume.
3.Squelch Knob- This control is used to cut off or eliminate receiver background noise in the absence of an incoming signal. For maximum receiver sensitivity it is desired that the control be adjusted only to the point where the receiver background noise is eliminated. Adjust until the receiver noise disappears.This will require the incoming signal to be slightly stronger than the average receiver noise. Fur- ther clockwise rotation will increase the threshold level which a signal must overcome in order to be heard. Only strong signals will be heard at a maximum clockwise setting.
4.XTRA Talk Mic Gain Knob- Adjusts the microphone gain in transmit and PA modes.This controls the gain to the extent that full talk power is available several inches away from the microphone. In the Public Address (PA) mode, the control functions as the volume control.
5.RF Gain
6.Delta Tune Knob- Turn this fine tuning knob clockwise to capture a more readable signal, as well as eliminate adjacent channel interference.
7.SWR Knob (Standing Wave
8.Guardian Alert Knob- This unique feature allows for the setting of a timed alert that can be used for many different things including keeping one alert while driving or setting an appointment reminder.To activate, turn the knob clockwise to choose a time increment- 1, 5, 10, 15, 20, 30, 40, 50, or 60 minutes. Once set, the radio will emit a loud beeping noise in the specified increment. For example, if you set the alarm for 15 minutes, after 15 minutes the alarm will sound.To snooze the alert for another 15 minutes, press the knob in once.
To deactivate, turn the knob to the OFF position. Warning:
The Guardian Alert is NOT intended as a substitute for adequate rest.You should not operate a vehicle if you are drowsy. During extended periods of vehicle operation, you should take frequent breaks. NEVER OPERATE A VEHICLE IF YOU ARE DROWSY.

9.Channel Selector Knob- This knob selects any one of the 40 Citizen Band channels.The selected channel is indicated by the LED readout, directly above the Channel Selector Knob.
10.
11.S/RF/SWR/CAL Switch- This switch selects meter function. S/RF is normal, SWR and CAL are for SWR measurements only. See pg 6 for calibration instructions.
12.NB/ANL/OFF Switch- When this switch is in the NB position, the RF Noise Blanker will be activated.The RF Noise Blanker is very effective for cutting down on ignition interference.When in the ANL position, the ANL is active to reduce background noise.
13.CB/WX/PA Switch- This switch allows you to move from CB mode to Weather (WX) scan mode and PA mode.When the Weather scan is activated, the radio will begin scanning and lock on the first weather channel broadcast signal strong enough to use. If later the signal becomes too weak to use the unit will automatically resume scanning to find a usable signal. In PA mode, incoming CB transmissions will be broadcast through the PA speaker.This allows you to hear transmissions when you are not inside your vehicle. The PA function should not be used unless a PA speaker is connected.
14.CH9/Nor/CH19 Switch- This switch is used for instant selection of Emergency Channel 9, Informational Channel 19 or Normal CB operation.
15.BRT/DIM Switch- Used to adjust the brightness of the LED.
16.XR Switch- This activates and deactivates the XR technology, which is a noise filter than helps improve tran- smission range.
17.TX LED- Indicates when the radio is transmitting.
18.ANT LED- Indicates a high SWR condition with the antenna system. Check antenna, cable and connections.
19.WX LED- Indicates when weather mode is activated.
