21-1599.fm Page 2 Thursday, August 5, 1999 10:59 AM
INTRODUCTION
Your Radio Shack TRC-499 40Channel 2-Way CB Radio is a high performance CB with the maximum allowable legal power and innovative styling.
This CB is perfect for recreational, business, or emergency use. You can call other people who have CBs at home, in their vehicles, or at camp sites. You can also connect optional equipment to your CB, such as an external PA speaker, or a DC power supply and base station antenna to set up a base station in your home.
Your CB has these features:
PLL (Phase-Locked Loop) Frequency Synthesizer —provides reliable and exact tuning using a precise frequency reference crystal.
Two Ceramic Filters — provide superior selectivity and prevent adja- cent-channel interference.
Hysteresis Squelch Circuit — compensates for fading signals and eliminates signal chopping during reception.
Automatic Noise Limiting (ANL) Circuit — reduces noise caused by nearby electrical equipment such as motors or automotive ignition systems.
DOWN/UP Channel Selector— provides maximum convenience when selecting channels.
LED Display — lets you easily see the selected channel number.
Universal Mounting Bracket— lets you mount your CB securely in your vehicle or on a table or shelf in your home.
Note: To use this CB, you need a mobile or base station antenna. Your local Radio Shack store has a wide variety of antennas. For more information, see “Installing an Antenna.”
For your records, we urge you to record your CB’s serial number in the space below. The serial number is on the CB’s back panel.

FCC INFORMATION
The Federal Communications Commission (FCC) does not require you to have a license to operate this CB. However, the FCC does require you to read and know Part 95 of FCC Rules. These rules apply to the operation of a Class D CB. We have provided a copy of these regulations with your CB.
Warning: Do not open your CB to make any internal adjustments. Any internal adjustments can be made only by authorized service personnel.
Internal adjustments and/or modifications can lead to illegal operation as defined by Part 95 of FCC Rules. Such illegal operation can lead to very serious consequences.
To be safe and sure:
•Never open your CB’s case.
•Never modify your CB.
Your CB might cause TV or radio interference even when it is operating properly. To determine whether your CB is causing the interference, turn off your CB. If the interference goes away, your CB is causing the interference. Try to eliminate the interference by:
•Moving your CB away from the receiver.
•Contacting your local Radio Shack store for help.
If you cannot eliminate the interference, the FCC requires that you stop using your CB.

INSTALLATION
MOUNTING THE MICROPHONE HOLDER
Using a Phillips screwdriver and the supplied small screws and small metal washers, attach the supplied microphone holder horizontally or vertically to either side of the CB.
CONNECTING THE MICROPHONE
1.Insert the microphone’s plug into the microphone jack until it clicks.
Caution: Never pull on the microphone cable.
MOUNTING THE
TRC-499
The most common mounting location for this CB is under a vehicle’s dashboard. However, if you use the TRC499 as a base station, you can place it on a desk, shelf, or table (see “Using the CB as a Base Station”).
If you are mounting the CB in a vehicle, choose a location where:
•You can easily reach the CB.
•Wires and cables will not interfere with the vehicle’s pedals or other moving parts.
•The CB is not directly in front of heating vents.
•All wires and cables will reach their connection points.
Cautions:
Caution: The microphone’s plug fits only one way into the microphone jack. Do not force it.
2.Slide the microphone onto the microphone holder.
To disconnect the microphone cable, squeeze the bottom of the microphone’s plug, then gently pull it out.
•The TRC-499 is designed to work in a vehicle that has a 12volt DC, negative-ground electrical system. Most vehicles have this type of system. If you are not sure about your vehicle, check with your vehicle dealer.

•If you use the TRC-499 in a vehicle, mount it securely to avoid damage to the CB or vehicle during sudden starts or stops.
Follow these steps to mount the CB using the supplied hardware.
1.Using the mounting bracket as a template, mark the positions for the screw holes.
4.Attach the CB to the mounting bracket using the rubber washers and mounting knobs.
2.In each marked location, drill a hole slightly smaller than the supplied large screws.
Caution: Be careful not to drill into anything behind the mounting surface.
3.Using a Phillips screwdriver, attach the mounting bracket to the mounting surface with the large screws and supplied lock washers.

INSTALLING AN
ANTENNA
Caution: To prevent damage to your CB, you must connect an antenna to the CB before you operate it.
Selecting an Antenna
When deciding on a mobile or basestation antenna and its location, consider these points:
•The location of the antenna should be as high as possible.
•The antenna and antenna cable should be as far as possible from sources of electrical noise (ignition systems, gauges, etc.).
•The antenna should be vertical for the best performance.
Your local Radio Shack store sells a variety of CB antennas for both mobile and base-station use. Choose the one that best meets your needs.
