INSTALLATIONSPEAKERS/NOISE INTERFERENCE

INSTALLATIONCB ANTENNA

1. Mount external speaker in desired location as shown

2. Plug into the back of the Connector Box

*The external speaker should have 4-8 ohms impedance and be able to handle at least 4 watts.

IGNITION NOISE INTERFERENCEThe alternator and ignition system in your vehicle may limit your ability to receive low signal levels.

Other noise interference can be the result of several different installation variables. Consult your Cobra dealer or a 2-way radio technician to help locate and correct the source of severe noise interference.

SOUNDTRACKER® SYSTEMWhile previous systems only “blanked out” or limited noise in higher sound frequencies, the revolutionary new SoundTracker® System actually reduces noise while leaving the signal intact in the reception mode. In the transmission mode, it actually strengthens the signal, providing you with a significant reduction in noise.

For the most reliable operation and maximum range, Cobra recommends using a vertically polarized, quarter–length whip antenna (illustration 1).

Shorter, loaded-type whips are adequate when maximum range is not required (illustration 2).

NOTE: Mobile installations (cars, trucks, boats, etc) should be made only with a non-directional antenna system.

• A standard antenna connector (Type SO-239) is provided on the Connector Box for easy connection to a standard PL-259 cable termination.

• Cobra antenna models are recommended; see your local CB dealer or order directly from Cobra. See order form on page ??.

• For maximum efficiency in boat installations, a ground plate is required, unless the vessel has a steel hull. Consult your CB dealer for information regarding an adequate grounding system.

OPERATIONSELECTING A CHANNEL

OPERATIONSETTING THE SQUELCH

To achieve the Desired Squelch Setting (DSS):

1. Turn SoundTracker on

2. Turn the Squelch Control (SQL) counterclockwise until you hear nothing but static.

3. Slowly turn the Squelch Control back clockwise, just until the static stops. This is the optimum receiving level, (DSS) allowing only strong signals to come through.

SOUNDTRACKERTM

SOUNDTRACKERTM

SOUNDTRACKERTM

SETTING THE SQUELCHThink of your Squelch Control as a gate for incoming signals. If you turn the Squelch Control fully clockwise, you effectively close the “gate” and no signals will pass through. If you turn the Squelch control fully counterclockwise, you open the gate and all signals come through.

SELECTING A CHANNEL

1. Change channels by pressing either the channel s up or channel t down key .

2. To quick-advance channels, press and hold either key.

HOW YOUR CB CAN SERVE YOU • Warn of traffic tie-ups ahead.• Provide weather and road information.• Provide help fast in event of emergency or break down.• Suggest good spots to eat and sleep.• Make long trips more interesting, and help keep you awake.• Provide direct contact with your office or home.• Make friends as you travel.• Provide “local information” to find your des ti na tion.• Communicate with friends and family during outdoor activities.• Help law enforcement officers by reporting drunk and reckless drivers.

WEATHER CHANNEL MESSAGESYou can receive up to the minute local area weather reports provided by NOAA (National Oceanic Atmospheric Administration) 24 hours a day, 7 days a week. An agency of the U.S. Department of Commerce, NOAA warns of dangerous weather, charts our seas and skies, guides our use and protection of ocean and coastal resources and conducts research to improve our understanding and stewardship of the environment.The National Weather Service operates about 380 stations. Approximately 90 percent of the Nation’s population is within listening range of a NOAA Weather Radio broadcast.A similar network of about 15 stations using the same frequencies broadcast continuous weather information across much of southern Canada.If you have a question concerning NOAA Weather Radio or wish to receive a listing of NOAA Weather Radio receiver locations, please contact your nearest National Weather Service Office, or write to National Weather Service (Attn: W/OM11), National Oceanic and Atmospheric Administration, Silver Spring, MD. 20910.

Note: Some areas may not have a broadcast tower within the transmission range of your 75WX.

A FEW RULES YOU SHOULD KNOW 1. You are not allowed to carry on a conversation with another station for

more than five minutes at a time without taking a one-minute break to give others a chance to use the channel.

2. You are not allowed to blast others off the air by overpowering them with illegally amplified transmitter power or illegally high an ten nas.

3. You can’t use the CB to promote illegal activities.4. You are not allowed to use profanity.5. You may not play music in your CB.6. You may not use your CB to sell merchandise or professional service.

Operating Procedure for Emergency Communications

1. For EMER GEN CY com mu ni ca tions, set radio to Ch. 9. For non-emergency com mu ni ca tions, select desired Channel by rotating the CHAN NEL UP/DOWN tuning knob until reach ing the desired Chan nel.Be sure the antenna is properly connected to the radio before trans-mit ting. Prolonged transmitting without an antenna, or use of a poorly matched an ten na, could cause damage to the transmitter.

2. When asking for aid on Channel 9 it is suggested that you request a REACT base to respond by saying “Break Channel 9 for a REACT base” and provide the CB DISTRESS DATA (called “CLIP):CALL SIGN-Identify yourself and vehicle.LOCATION-Be exact.INJURIES-Number. Type. Trapped?PROBLEM- Give details and help required. Air CLIP repeatedly so any monitor can aid you.

If you don’t receive a response on Ch. 9; try Ch.14 or 19.

USE CHANNEL 9 FOR EMERGENCY ONLY

FCC gives the following examples of permitted and prohibited types of com mu ni ca tions for use on Channel 9. These are guidelines and are not intended to be all-inclusive.

Permitted Example Message

Yes “A tornado sighted six miles north of town.”

No “This is observation post number 10. No tornado sighted.”

Yes “I am out of gas on Interstate 95 at mile marker 121.”

No “I am out of gas in my driveway.”

Yes “There is a four-car collision at Exit 10 on the Beltway, send police and ambulance.”

No “Traffic is moving smoothly on the Beltway.”

Yes “Base to Unit 1, the Weather Bureau has just issued a thun der storm warning. Bring the sailboat into port.”

No “Attention all motorists. The Weather Bureau advises that the snow to mor row will accumulate 4 to 6 inches.”
