TRC-230 (210-1668) Operation Faxback Doc. # 16745 Before you use the walkie-talkie, you should know how to use it effectively and courteously. The section "CB Operation Tips" contains information that will help you get more enjoyment from the walkie-talkie. RECEIVING TRANSMISSIONS AND ADJUSTING SQUELCH CAUTION: You must first connect an antenna before you can use the walkie- talkie (see "Connecting the Flexible Antenna"). 1. Turn SQUELCH fully counterclockwise. 2. To turn on the walkie-talkie, turn OFF/VOLUME clockwise until you hear a hissing sound. The walkie-talkie briefly displays a channel number. 3. Slowly turn SQUELCH clockwise to a point just after the hissing sound stops. NOTE: If the walkie-talkie picks up unwanted, partial, or weak transmissions, turn SQUELCH clockwise to decrease the walkie- talkie's sensitivity to these signals. Turn SQUELCH counterclockwise if you want to listen to a weak or distant station. 4. Press LIGHT to display the channel number. If desired, press CHANNEL [up arrow] or [down arrow] to select the desired channel. The channel number appears on the display for about a second. Important! Channel 9 is reserved for motorist assistance and for reporting emergency information about accidents, hazardous road conditions, and so on. Always give emergency messages priority on Channel 9. 5. To turn off the walkie-talkie, turn OFF/VOLUME counterclockwise until you hear it click. TRANSMITTING 1. Follow the steps described in "Receiving Transmissions and Adjusting Squelch." 2. Hold the walkie-talkie 2 or 3 inches from your mouth. Press and hold down the PUSH TO TALK button on the left side of the walkie-talkie and speak into the microphone in a normal voice. When you finish transmitting, release PUSH TO TALK. NOTES: The walkie-talkie's automatic modulation circuit adjusts the microphone's sensitivity to allow a wide variety of voice levels. Do not speak too loudly when transmitting. It does not make your signal any stronger, and might distort your transmission. 3. To increase the transmitted signal strength, set the POWER switch on the top of the walkie-talkie to HI. To decrease the transmitted signal strength and save battery power, set POWER to LOW. 4. To turn off the walkie-talkie, turn OFF/VOLUME counterclockwise until you hear it click. USING THE DISPLAY LIGHT Press and hold LIGHT to display the channel number. CB OPERATION TIPS Like most activities, CB radio has its customs and courtesies. The following tips will help you get the most enjoyment from the walkie-talkie. COMMON USES FOR A CB RADIO Business Uses Truck drivers and delivery personnel can learn road and traffic conditions and get assistance in locating destinations. A CB is also good company on those long hauls. On construction crews, a CB quickly pays for itself when you are calling for additional materials or coordinating the activities of different work crews. For security officers, a CB is more than a convenience - it is a must for safety and efficiency. Personal Uses Keep in touch with home while driving to work, to the store, or to a social activity. Let your family know you are tied up in traffic 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 assurance it is to be able to radio for assistance. Camping, fishing, and other sports are more fun with a CB. Locate a buddy or find out what's cooking back at camp. CB COURTESY 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 attempt, sign off and wait several minutes before trying again. Do not hold down the transmit button when you are not talking. (This is called dead keying.) Assist callers with directions, information about road conditions, and any other reasonable requests. MAXIMUM RANGE The maximum range and quality of CB transmissions vary depending on these conditions: Amount of power in the batteries. The type and quality of antenna. The height of the antenna's mounting location - the higher the antenna, the better the signal's range. The surrounding terrain (mountains or tall buildings limit range). The weather conditions. The number of nearby CBs operating on the same channel. The standing wave ratio (SWR) between the antenna and the walkie-talkie and a mobile or base-station antenna using an SWR tester (Cat. No. 21- 523). Follow the SWR tester's instructions. NOTE: The SWR between the walkie-talkie and the supplied flexible antenna is preset. You cannot change it. To ensure maximum range, keep fresh alkaline or fully charged nickel- cadmium batteries in the walkie-talkie. USING COMMON 10-CODES Citizen's band operators have largely adopted the 10-codes for standard questions and answers. These codes permit faster communication and better intelligibility in noisy areas. This table lists the codes adopted by the Associated Public Safety Communications Officers (APCO). Code Meaning 10-1 Cannot understand your message. 10-2 Your signal is good. 10-3 Stop transmitting. 10-4 Message received and understood. 10-5 Relay information to _______________. 10-6 I am busy or are you busy? 10-7 Out of service. 10-8 In service. 10-9 Repeat last message. 10-10 Negative (No). 10-11 _______________ in service. 10-12 Stand By. 10-13 Report ___________ conditions. 10-14 Information. 10-15 Message delivered. 10-16 Reply to message. 10-17 En route. 10-18 Urgent. 10-19 Contact _______________ 10-20 What is your location? 10-21 Call _______________ by telephone. 10-22 Cancel last message. 10-23 Arrive at the scene. 10-24 Assignment complete. 10-25 Meet ______________. 10-26 Estimated time of arrival is ___________. 10-30 Use caution. 10-31 Pick up. 10-33 Emergency traffic. Clear the channel. 10-34 What time is it? (llg/all-08/29/95)
