Business Uses ••Truck drivers and delivery personnel can learn road and traffic conditions and get assistance in locating desti- nations. A CB is also good compary on those “long hauls”. • On construction crews,a CB quickly pays for itself when you are calling for additional materials or coordinat- ing the activities of different work crews. •For security officers,a CB is more then a convenience – it is a must for both safety and difficiency. 12
Personal Uses •• Keep in touch with home while driv- ing to work ,to the store,or to a so- cial activity.let your family know you are tied up in traffice or that you will stop by the store on the way home. •If you are a two-car(or more)family, CBs are great for communicating With family members while they are In their cars. •Contact friends or neighbors-find out “what’s happening”or plan a get-together •Ever have car trouble or run out of gas on the highway?What an assur- ance it is to be able to call for assis- tance! •Camping,fishing,and other sports are more fun with a CB.Locate a buddy or find out”what’s cooking” back at camp. TRANSMISSION COURTESY Please follow these guidelines of redio courtesy when using your CB. • Wait for a pause in someone else’s transmission before you ask for a break. •If you do not receive an answer to your call after a second attampt, sign off and wait several minutes be- fore trying again. •Do not hold down the talk button when you are not talking(This is called dead keying). •Assist callers with directions,infor- mation about road conditions,and any other reasonable requests. MAXIMUM RANGE The maximum range and quality of CB Transmissions very depending on the foliowing conditions: •The type and quality of antenna used •the height of the antenna’s moun- ting location the higher the an- tenna, the better the signal’s range •the surrounding terrain moun- tains and tall bulinings limit the range •weather conditions •The number of neardy CBs operat- ing on the same channel •standing wave ratio(SWR)between the antenna and the CB. Note: Your CB radio’s transmission range is generally line-of –sight. REDUCING NOISE The Audio Clarity Enhance(ACE)cir- cuit uses compander(compressor and ex-pander)technology to improve communication quality.The circuit maintains the dymanic ragng while increasing the signal-to-noise ratio as the gain s automatically level. This results in a reduction in wide band noise. Because your CB is exceptionally qui- et,any noise you hear is probably from 13 anexternal source in you vehicle, such as the alternator,another radio, or spark plugs. You can determine the noise’s Source by turning off the engine and Operating the CB with your vehicle’s Ignition set to ACC.If the noise is reduced,the problem is in your vehicle’s ignition or electri- cal system. Here are a few hints to help you reduce or elimintate such noise: •Make all CB power and antenna wires as short as possible. •Keep the power wires away from the antena wires. •Be sure the chassis ground connec- tion is secure. •Replace old ignition wires with new, high-voltage, noise-suppression wires. •Install noise suppressors on your spark plugs, or install new spark plugs that have built-in noise suppressors. •lf problems persist,check your alter- nator/generator and regulator gauges You can reduce the noise from these sources by using bypass capacitors atthe various output voltage points. Your local RadioShack store has a Wide selection of noise-suppression accessories.
