71. Rotate OFF/VOLUME clockwise to turn on the CB.2. To decrease CB sensitivity, slowly rotate SQUELCHclockwise until the hissing sound stops. To increasesensitivity, rotate SQUELCH counterclockwise. Ô3. Adjust VOLUME to a comfortable listening level.4. To tune to a channel, rotate the knob on the front of theradio, or press UP/DN on the microphone. Ô5. If necessary, rotate RF GAIN clockwise to boost signalstrength.6. When you are finished, turn off the CB.TRANSMITTINGBefore transmitting, adjust CB, S/RF, NOR, and SQUELCH tomatch the illustration under “Receiving” .1. Follow steps 1-3 in “Receiving”. Ô3. Rotate MIC GAIN clockwise or counterclockwise toadjust the mic gain.4. When you are finished speaking, release PTT. The CBcan receive transmissions on the selected channel.5. When you are finished, turn off the CB.Ô NOTE Ô• If the CB picks up partial or veryweak transmissions, continue toturn SQUELCH clockwise todecrease the CB's sensitivity tothese signals. Turn SQUELCHcounterclockwise if you want tolisten to a weak or distantstation.• Selecting either Channel 9 or 19overrides the manual channelselection control.• All channels, with the exceptionof Channels 9 and 19, areavailable for generalcommunications. Channels 9and 19 are reserved for motoristassistance and for reportingemergency situations,hazardous road conditions, andthe like. To quickly tune toChannel 9 or 19, setCH9/NOR/CH19 to CH9 orCH19.• Do not speak too loudly whentransmitting. It does not makeyour signal any stronger, andmight distort your transmission.• If you want to monitor Channel 9during CB operation, setDUAL/OFF to DUAL.• If you hear a low-level popping-type noise, set NB/OFF/MON toNB to turn on the noise blankingcircuit. This helps minimizebackground noise.2. Hold down PTTand speak intothe microphone.While transmitting, yourtransmission strength isshown on the signal meter.21-1576_rsj_012604.fm Page 7 Monday, January 26, 2004 11:39 AM
