plied machine screws and lock washers.  
this CB is under a vehicle’s dashboard.  
However, if you use the TRC-519 as a  
base station, you can place it on a desk,  
shelf, or table (see “Using the CB as a  
Base Station” on Page 7).  
If you are mounting the CB in a vehicle,  
choose a location where:  
• you can easily reach the CB.  
• wires and cables are clear of the ve-  
hicle’s pedals or other moving parts.  
To attach the holder to another location  
in the vehicle, such as the dashboard,  
follow these steps.  
• the CB is not directly in front of heat-  
ing vents.  
1. Using the holder as a template,  
mark the positions for the mounting  
screw holes at the desired location.  
• all wires and cables can reach their  
connection points.  
2. At each marked position, drill a hole  
slightly smaller than the supplied  
mounting screws.  
Warning: If you use the CB in a vehicle,  
mount it securely to avoid damage to the  
CB or vehicle or injury to anyone in the  
vehicle during sudden starts or stops.

cable to the CB and connect the cable to  
the ANT. jack on the back of the CB.  
Caution: Never pull on the micro-  
phone’s cable.  
CONNECTING AN  
ANTENNA  
Cautions:  
There are many different types of CB  
antennas for mobile CBs. Each antenna  
type has its own benefits, so choose the  
one that best meets your needs. Your  
local RadioShack store sells a wide vari-  
ety of antennas.  
• Avoid routing the cable next to sharp  
edges or moving parts, which might  
damage the cable.  
• Do not run the cable next to power  
cables or other radio antenna ca-  
bles.  
• Do not run the cable through the en-  
gine compartment or other areas  
that produce extreme heat.  
Note: If you are using this CB as a base  
station, see “Using the CB as a Base  
Station” on Page 7.  
For maximum range, adjust the anten-  
na’s Standing Wave Ratio (SWR) using  
an SWR meter (not supplied).  
When you choose an antenna, keep in  
mind that for the best performance you  
should mount the antenna:  
• as high as possible on the vehicle  
Follow the instructions supplied with the  
SWR meter and antenna to adjust your  
antenna’s SWR to the lowest possible  
value. SWR values of 2.0:1 are general-  
ly acceptable, with readings of 1.5:1 or  
lower being more desirable.  
• as far as possible from sources of  
electrical noise  
• vertically

USING THE CB AS A  
BASE STATION  
1. Connect the red wire (with the in-  
line fuse holder) on the back of the  
CB to a terminal in your vehicle’s  
fuse box that has power only when  
the ignition is in the ACC (acces-  
sory) or ON position.  
Although this CB is designed mainly for  
mobile use, you can also use it as a  
base station with an AC power source.  
For base station installation, you need  
these items.  
• a 12-volt DC power supply that can  
supply at least 1.5 amps  
2. Connect the black ground wire to a  
metal part of the vehicle’s frame  
(chassis ground).  
Caution: Most 12-volt DC power  
supplies plug into a standard AC  
outlet to produce DC power. Before  
connecting your CB to a 12-volt DC  
power supply, read and follow the in-  
structions included with the power  
supply.  
Caution: Do not connect the black  
wire to a non-metallic (plastic) part,  
or to any part insulated from the ve-  
hicle’s chassis by a non-metallic  
part.  
• base station antenna  
• coaxial antenna cable and connec-  
tors

operation.  
Note: The microphone’s talk button  
does not work when CB/WX is set to WX.  
Using Weather Alert/SAME  
When CB/WX is set to CB and the CB is  
on, it automatically functions as a severe  
weather warning radio by sounding an  
alert when it detects a weather alert sig-  
nal. This is especially useful when your  
area is expecting severe weather condi-  
tions.  
To reduce the alert tone levels for sub-  
sequent alerts, hold down  
OFF  
ALERT TONE  
for about 2-seconds. The tone  
stops and the indicator flashes slowly. If  
the radio receives a new SAME code  
weather alert, three low-level, short  
beeps sound while the indicator light  
flashes slowly.  
When your local weather station broad-  
casts a severe weather alert signal, the  
CB sounds an alert tone and the radio’s  
SAME ALT indicator lights according to  
the emergency level encoded in the sig-  
nal  
To return to the full alert mode, press the  
microphone’s talk button or switch to  
WX.  
To listen to the weather information after  
the radio receives an alert, set CB/WX to  
WX. The SAME/ALT indicator turns off.

Notes:  
COMMON USES FOR A CB  
• Because of atmospheric conditions,  
you might encounter times when the  
signal your radio receives does not  
contain information relevant to the  
emergency level of the alert. This is  
normal.  
Like most activities, CB radio has its  
customs and courtesies. The following  
tips will help you get the most enjoyment  
from your CB.  
Business Uses  
• The radio will sound an alert regard-  
less of the channel setting.  
Truck drivers and delivery personnel  
can learn road and traffic conditions  
and get assistance in locating desti-  
nations. A CB is also good company  
on those “long hauls.”  
• The CB will not sound an alert while  
you are transmitting.  
Caution: If you are in a rural or fringe  
area, your radio might be triggered by  
an alert broadcast in one area, but not  
be triggered if you travel to another area  
(even close by).  
• On construction crews, a CB quickly  
pays for itself when you are calling  
for additional materials or coordinat-  
ing the activities of different work  
crews.  
To verify actual reception, your radio  
must receive a test or emergency alert  
broadcast. In the US, the National  
Weather Service (NWS) broadcasts a  
test alert every week on Wednesday be-  
tween 11 AM and 1 PM. To find out the  
specific test schedule in your area, con-  
tact your local NOAA or National Weath-  
er Service office. These offices are  
usually listed in the telephone directory  
under “US Government, Department of  
Commerce.”  
• For security officers, a CB is more  
than a convenience — it is a must  
for both safety and efficiency.  
Personal Uses  
• Keep in touch with home while driv-  
ing to work, to the store, or to a so-  
cial 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.

21-1709.fm Page 13 Monday, January 29, 2001 10:29 AM  
• Ever have car trouble or run out of  
gas on the highway? What an assur-  
ance it is to be able to call for assis-  
tance!  
• the height of the antenna’s mounting  
location — the higher the antenna,  
the better the signal’s range  
• the surrounding terrain — moun-  
tains and tall buildings limit the  
range  
• Camping, fishing, and other sports  
are more fun with a CB. Locate a  
buddy or find out “what’s cooking”  
back at camp.  
• weather conditions  
• the number of nearby CBs operating  
on the same channel  
TRANSMISSION  
COURTESY  
• standing wave ratio (SWR) between  
the antenna and the CB.  
Please follow these guidelines of radio  
courtesy when using your CB.  
Note: Your CB radio’s transmission  
range is generally line-of-sight.  
• Wait for a pause in someone else’s  
transmission before you ask for a  
break.  
REDUCING NOISE  
• If you do not receive an answer to  
your call after a second attempt,  
sign off and wait several minutes be-  
fore trying again.  
The Audio Clarity Enhance (ACE) circuit  
uses compander (compressor and ex-  
pander) technology to improve commu-  
nication quality. The circuit maintains  
the dynamic range while increasing the  
signal-to-noise ratio as the gain is auto-  
matically controlled according to the in-  
put signal level. This results in a  
reduction in wide band noise.  
• Do not hold down the talk button  
when you are not talking. (This is  
called dead keying.)  
• Assist callers with directions, infor-  
mation about road conditions, and  
any other reasonable requests.  
Because your CB is exceptionally quiet,  
any noise you hear is probably from an  
external source in your vehicle, such as  
the alternator, another radio, or spark  
plugs.  
MAXIMUM RANGE  
The maximum range and quality of CB  
transmissions vary depending on the fol-  
lowing conditions:  
You can determine the noise’s source  
by turning off the engine and operating  
the CB with your vehicle’s ignition set to  
ACC. If the noise is reduced, the prob-  
lem is in your vehicle’s ignition or electri-  
cal system.

21-1709.fm Page 14 Monday, January 29, 2001 10:29 AM  
Here are a few hints to help you reduce  
or eliminate such noise:  
• Make all CB power and antenna  
wires as short as possible.  
• Keep the power wires away from the  
antenna wires.  
• Be sure the chassis ground connec-  
tion is secure.  
• Replace old ignition wires with new,  
high-voltage,  
wires.  
noise-suppression  
• Install noise suppressors on your  
spark plugs, or install new spark  
plugs that have built-in noise sup-  
pressors.  
• If problems persist, check your alter-  
nator/generator  
and  
regulator  
gauges. You can reduce the noise  
from these sources by using bypass  
capacitors at the various output volt-  
age points.  
Your local RadioShack store has a wide  
selection of noise-suppression accesso-  
ries.

CARE AND MAINTENANCE  
Your RadioShack TRC-519 40-Channel Mobile CB Radio is an example of superior  
design and craftsmanship. The following suggestions will help you care for your CB  
so you can enjoy it for years.  
Keep the CB dry. If it gets wet, wipe it dry immediately. Liquids might con-  
tain minerals that can corrode the electronic circuits.  
Use and store the CB only in normal temperature environments. Temper-  
ature extremes can shorten the life of electronic devices and distort or  
melt plastic parts.  
Keep the CB away from dust and dirt, which can cause premature wear  
of parts.  
Handle the CB gently and carefully. Dropping it can damage circuit  
boards and cases and can cause the CB to work improperly.  
Wipe the CB with a damp cloth occasionally to keep it looking new. Do  
not use harsh chemicals, cleaning solvents, or strong detergents to clean  
the CB.  
Modifying or tampering with the CB’s internal components can cause a malfunction  
and might invalidate its warranty and void your FCC authorization to operate it. If  
your CB is not performing as it should, take it to your local RadioShack store for as-  
sistance.

REPLACING THE FUSE  
THE FCC WANTS YOU TO  
KNOW  
The TRC-519’s 2-amp in-line fuse helps  
protect your CB from power surges and  
short circuits. When replacement is re-  
quired, use a 2-amp, fast-acting glass  
fuse, available at your local RadioShack

Your CB might cause TV or radio inter-  
ference even when it is operating prop-  
erly. To determine whether your CB is  
causing the interference, turn off your  
CB. If the interference goes away, your  
CB is causing it. Try to eliminate the in-  
terference by:  
Follow these steps to replace the fuse.  
• moving your CB away from the re-  
ceiver  
• contacting your local RadioShack  
store for help  
If you cannot eliminate the interference,  
the FCC requires that you stop using  
your CB radio.  
Any adjustments to a CB must be made  
by a qualified technician using the prop-  
er test equipment.  
1. Make sure the vehicle and CB are  
both off.  
2. Hold the fuse holder at both ends,  
push the ends together, twist one  
end counterclockwise, and pull them  
apart.  
To be safe and sure:  
• Never open your CB radio’s case.  
• Never change or replace anything in  
your CB radio.  
3. Remove the old fuse and inspect its  
condition. If it is blown, insert a new  
one of the same type and rating. If it  
is not blown, reinsert it.  
Caution: Do not use a fuse with rat-  
ings other than those specified here.  
Doing so might damage your TRC-  
519.  
4. Push the fuse holder ends together  
and twist one end clockwise.
