SAFETY NOTICE

The antenna used for this radio must be properly installed and

maintained and must provide a separation distance of at least 34 cm

(13.4 Inches) from all persons and must not be collocated or operated in

conjunction with any other antenna or transmitter. Never transmit if any

person is closer than the specified distance to the antenna.

Note that Uniden does not specify or supply any antenna with this

transceiver. While a 0 dBi gain antenna is normal for a typical installation,

the above limit applies to any antenna with up to 3 dBi gain.

This device complies with Industry Canada licence-exempt RSS

standard(s). Operation is subject to the following two conditions: (1) this

device may not cause interference, and (2) this device must accept any

interference, including interference that may cause undesired operation.

Changes or modifications to this product or use of accessories not

expressly approved by Uniden, or operation of this product in any way

other than as provided in the Uniden Owner’s Manual could void your

authority to operate this product.

DESCRIPTION

Your Uniden PC78XL+ is a high-quality communications device designed

for use in the Citizens Band Radio Service. It will operate on any of the 40

AM frequencies authorized by the Federal Communications Commission

(FCC).

FCC PART 15 COMPLIANCE

The Citizens Band Radio Service is under the jurisdiction of the Federal

Communications Commission (FCC). Any adjustments or alterations

which would alter the performance of the transceiver’s original FCC

certification, or which would change the frequency determining

method, are strictly prohibited. Replacement or substitution of crystal,

transistors, ICs, regulator diodes, or any other part of a unique nature,

with parts other than those recommend by Uniden, may cause violations

of the technical regulations in Part 95 of the FCC Rules or in violation of

certification requirements in Part 2 of the rules.

EMERGENCY OPERATION

1. Set the switch to CH9 or turn Channel Selector knob to Channel 9.

2. Press the microphone PTT switch and speak clearly.

3. If there is no response, select an active channel and ask that party

to relay your emergency broadcast on Channel 9.

All channels except Channel 9 may be used for normal communication.

Channel 9 is reserved by the FCC for emergency communication

involving the immediate safety of individuals or protection of property.

Channel 9 may also be used to render assistance to others.

This is an FCC rule and applies to all operators of CB radios.

CONTROLS AND FUNCTIONS

1. Microphone jack

The PC78XL+ is precongured for Uniden’s wireless, noise-canceling

microphone technology. Visit www.uniden.com to order Uniden’s 6-pin

wireless microphone and adapter.

2. ON OFF - VOLUME: Turns radio on or o; adjusts speaker volume.

3. SQUELCH: Reduces background noise when there is no incoming

signal.

4. RF GAIN inner knob: Improves reception in strong signal areas.

5. MIC GAIN outer knob: Adjusts microphone sensitivity.

6. DELTA inner knob: Fine tunes the receiver.

7. SWR outer knob: Calibrates the meter for Standing Wave Ratio

(SWR) measurements.

8. Channel knob: Selects channel.

9. Channel Display: Displays current channel selection.

10. RX/TX LED: Red-transmitting; green-receiving.

11. ANT LED: Indicates a high SWR condition in antenna system.

Check antenna, cable, and connections.

12. Dynamic Squelch Control (DSC) switch: Automatically sets

Squelch to optimal level for stronger signals.

13. CH9/OFF switch: Turns Channel 9 on or o.

14. BRT/DIM switch: Adjusts the LED brightness.

15. CB/PA switch: Selects CB (Citizen’s Band) or PA (Public Address).

Do not use PA function unless an external speaker is connected.

16. NB/ANL switch: Reduces external noise and interference from

vehicle ignition systems.

17. S/RF/SWR/ CAL switch: Selects meter function. S/RF - normal;

SWR and CAL are for SWR measurements only. See page 8 for

calibration procedures.

18. Multi-function meter: Measures SWR, RF and S signal strength.

19. POWER connector: Connects DC power to transceiver.

20. EXT. SP. jack: Connects optional 8-ohm 4-watt speaker to

remotely monitor the receiver.

When the external speaker is plugged in, the internal speaker is o.

21. PA SP. jack: Connects external 8-ohm, 4-watt speaker.

To prevent acoustic feedback, separate the microphone from the speaker

when operating the PA at high output levels.

22. Antenna socket: Connects antenna cable to transceiver.

INSTALLATION

MOBILE STATION INSTALLATION

Plan the location of the transceiver and microphone bracket before

beginning installation.

1. Select a location that is convenient for operating the radio, but

does not interfere with the driver or passenger.

2. Install bracket with self-tapping screws provided.

3. Connect wiring. (See instructions for Connecting the Power

Cords.)

4. Attach the microphone bracket to the side of the radio.

5. Attach radio to bracket.

MOBILE STATION ANTENNA

Because the maximum power output of the transmitter is limited by

the FCC, the quality of your antenna is very important. To achieve the

maximum transmission distance, we strongly recommend that you

install only a high quality antenna. You have just purchased a superior

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.

Your Uniden dealer is qualified to help you select the proper antenna for

your requirements. A whip style antenna may be used for automobile

installation.

A short “loaded” whip antenna is easier to install on an automobile.

However, the efficiency of the short whip antenna is less than that of a

full quarter-wave whip antenna.

MARINE INSTALLATION

Consult your dealer for information regarding marine installation. It is

important to adequately ground the system and to prevent electrolysis

between the fittings in the hull and the water.

CONNECTING THE POWER CORDS

Uniden recommends connecting the power lead to the Ignition Switch

Accessory Terminal. This way, the transceiver is automatically turned off

when the ignition switch is turned off.

As an alternative, the power cord may be connected to an available

terminal on the fuse block or to a point in the wiring harness. However,

take care to prevent a short circuit. If in doubt, contact your vehicle

dealer for information.

This transceiver may be installed and used in any 12-volt DC negative

ground system vehicle.

GROUND INFORMATION

Most newer U.S. and foreign made cars and small trucks use a negative

ground system. Some older cars, and some new large trucks, use a

positive ground system.

With a negative ground system, the negative (-) battery terminal is

usually connected to the vehicle motor block. If you cannot determine

the polarity system of your vehicle, contact your vehicle dealer for

information.

Negative Ground System

For negative ground systems, connect the red DC power cord from the

transceiver to the positive (+) battery

terminal or other convenient point.

Then connect the black power cord

to the vehicle chassis or negative (-)

battery terminal.
