Uniden PC122XL AM and SSB CB Radio Owner’s Manual

Uniden PC122XL AM and SSB CB Radio

WELCOME
To the world of sophisticated, microprocessor controlled AMSSB radio communications. Your Uniden PC122XL represents one of the most advanced mobile type radio ever designed for use in the Citizens Band Radio Service. It will operate on any of the 40 AM frequencies and Upper and Lower Side Band Frequencies designated by the Department of Transport and Communications (DOTAC). Your PC 122 XL features a frequency synthesizing circuit with PHASE LOCK LOOP techniques to assure precise frequency control. This radio has been type accepted and certified by the DOTAC.

WARNING- Before transmitting with your transmitter, you must obtain a Department of Transport and Communications Citizens Band Radio Service (CBAS) License. Obtain a brochure and a CBAS License Application form in your nearest DOTAC office. Mail the completed application form and the appropriate tfee to the Superintendent Regulatory af Licensing in the State of Territory in which the station will be operated.

MOBILE INSTALLATION
Plan the location of the radio and microphone bracket before starting installation. Select a location that is convenient for operation and does not interfere with the driver or passenger in the vehicle. The radio should be securely fastened to a solid surface using the mounting bracket and self- tapping screws which are provided.

MOBILE ANTENNA
Since the maximum allowable power output of the transceiver is limited by the DOTAC, the antenna is a very important factor affecting transmission distance. t is for this reason that we strongly recommend that you install only a quality antenna in your new CB radio system. You have purchased a superior quality transceiver. Don’t diminish its performance by installing an inferior antenna. Only a properly matched antenna system will allow maximum power transfer from the 50 ohm transmission line to the radiating element. We recommend that you use an SWR meter when installing your antenna. Set your PC122XL to channel 20 and adjust to SWA

1. Your UNIDEN dealer is qualified to assist you in the selection of the proper antenna to meet your application requirements.

For automobile installation, the whip antenna may be used with good effect. The most efficient and practical installation is a full quarter wave whip antenna mounted on the rear deck or fender top, midway between the rear window and bumper A short “loaded” whip antenna is more convenient to install on your automobile although the efficiency is less than a full quarter wave whip antenna. For marine installation, consult your dealer for information regarding an adequate grounding system and prevention of electrolysis between fittings on the hull and water

CONNECTING THE POWER CORDS
With regard to the connection of the power cords, it may be possible or desirable to connect the red lead (for negative ground systems) or the black lead (for positive ground systems) to the ignition switch accessory terminal so that the radio is automatically turned off when the ignition switch (key) is turned off. Alternately, the power lead may be connected to an available terminal on the fuse block or even to a point in the wiring harness. Care must be taken, however, to guard against a short circuit condition. When in doubt, please contact your vehicle dealer for specific information for your vehicle.

GROUND INFORMATION
A negative ground system is generally identified by the battery terminal being connected to the vehicle motor block, but if you cannot determine the polarity of your vehicle, consult your vehicle dealer for information.

NOTE: This radio may be install led and used in any 12-volt DC negative or positive ground system.

NEGATIVE GROUND SYSTEM
If you are operating on a negative ground system, connect the, red DC power cord from the radio to the positive “+” battery terminal or other convenient point and connect the black power lead to the chassis or vehicle frame, or the negative”-” terminal of the battery.

POSITIVE GROUND SYSTEM
If you are operating on a positive ground system, connect the black DC power cord from the radio to the negative “-” battery terminal or other convenient point and connect the red power lead to the chassis or vehicle frame, or the positive ” +” terminal of the battery.

CONTROL AND FUNCTION

1. SQUELCH The squelch control is used to eliminate background noise during the absence of a transmission. Turn the control fully counterclockwise, then slowly rotate it back clockwise until all noise disappears. At this setting any transmission must be slightly stronger than the background noise to “Break Squelch” or to be heard. Further clockwise rotation will increase the threshold at which a signal will be heard. You can select any level to “Break Squelch”.

2. S/RF METER This LED meter shows the relative strength of the received signal or transmit power,

3. CHANNEL INDICATOR – Displays the channel currently in use.

4. CHANNEL SELECTOR This switch selects the desired channel for transmission and reception. All channels, except channel 9, may be used for communications between stations operating under different license. Channel 9 has been reserved by the DOTAC for emergency communications involving the immediate safety of individuals or the immediate protection of property. This is the DOTAC rule and applies to all operators of CB radios.

5. TX INDICATOR An LED lights to indicate when the radio is transmitting.

6. MICROPHONE- The operational mode of the CB is controlled by the push-to- talk switch on the microphone. Press the switch to activate the transmitter and disable the receiver. Release the switch to enable the receiver and disable the transmitter. When transmitting, hood the microphone about 2 inches from your mouth and speak clearly in a normal voice. The microphone included with the PC122XL is a detachable, low impedance, dynamic type.

7. RF GAIN This control is used to adjust signal reception in areas where strong signals are present. Turn the control fully clockwise for maximum reception.

8. VOLUME CONTROL Rotate clockwise to turn radio on and to increase volume.

9. NB/ANL SWITCH You can select either Noise Blanker and Automatic Noise Limiter, only Automatic Noise limiter or all filters OFF. The NB and ANL help to reduce harsh background noise caused by a variety of interference sources. The ANL will not work in the USB or LSB mode.

10. PA SWITCH – Move this switch to the Public Address mode when an external PA speaker is connected. When the PA mode is selected, you can use the PA function and yet can monitor CB incoming signals. Adjust the PA output level by rotating the volume control.

11. AM/SsSB SELECTOR – The three position switch allows you to select AM (standard 40 channel CB) or USB (Upper Side Band) or LSB (Lower Side Band) operation.

12. CLARIFIER – Turn this control to achieve the best tuning of the upper or lower side band receiving frequency.
    

13. ANTENNA CONNECTOR – This female connector permits connection of the transmission line cable male connector (PL-259) to the transceiver.

14. PUBLIC ADDRESS An external 8 ohm 4-watt speaker must be connected to the “PA SP” jack located on the back of the unit. The speaker must be directed away from the microphone to prevent feedback.

15. EXTERNAL SPEAKER – The external speaker jack is used for remote receiver monitoring. The external speaker should have an 8 ohm impedance and be rated at least 4 watts. When an external speaker is connected, the internal speaker is disabled.

16. POWER-This plug permits connection of the DC power to the transceiver. The supplied DC Cord’s plug is polarized which ensures that power will always be connected and fused properly.

OPERATING PROCEDURE TO RECEIVE

1. Be sure that the power source, antenna and microphone are properly connected.
2. Turn the unit on by rotating the Volume control clockwise.
3. Set the channel selector switch to the desired channel.
4. Set the Volume control to a comfortable listening level.
5. Listen to the background noise from the speaker. Turn the Squelch control clock wise until the noise disappears (no signal should be present). Leave the control at -4 this setting. The squelch is now properly set. The receiver will remain quiet until a signal is actually received. Do not advance the control too far, or some weaker signals will not be heard.

OPERATING PROCEDURE TO TRANSMIT

1. Select the desired channel for transmission.
2. If the channel is clear, depress the push-to-talk switch on the side of the micro phone and speak in a normal voice.

CAUTION: The transceiver Voltage Standing Wave Ratio (V.S.W.R.) measurement must be performed prior to the use of the transmitter. A “V.S.W. R.” ratio in excess of 2:1 may damage the transmitter. OPERATION OF SSB Choose the desired side band frequency by, A; select standard channel (1 40), B; select Upper or Lower side band by moving AM/SSB switch. Transmit or receive according to previous instructions. When receiving a side band transmission you may need to use the Clarifier control to fine tune that frequency. Rotate the Clarifier clockwise or counterclockwise for optimum reception. PREVENTATIVE

MAINTENANCE

At six to twelve month intervals, the following system checks should be made

1. Check the Standing Wave Ratio (V.S.W.R.)
2. Inspect all electrical connections.
3. Inspect antenna coaxial cable for wear.
4. Inspect all screws and other mounting hardware.
