COMMON USES FOR A CB
Like most activities,CB radio has its
Customs and and courtesies.The following
Tips will help you get the most enjoyment from your CB.
Business Uses
• Truck drivers and delivery personnel
can learn road and traffic conditions
and get assistance in locating destinations. A CB is also good compary
on those “long hauls”.
UsingCompass
• On construction crews,a CB quickly
pays for itself when you are calling
for additional materials or coordinating the activities of different work
crews.
This Mode displays current direction
and CB channel.Plus You can use CB
function(R/Tx) Without friction in this
mode as well.(Display direction & Ch.
by turns)
•For security officers,a CB is more
then a convenience – it is a must
for both safety and difficiency.

Personal Uses
• Keep in touch with home while driving to work ,to the store,or to a social activity.let your family know you
are tied up in traffice 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
•Ever have car trouble or run out of
gas on the highway?What an assurance it is to be able to call for assistance!
MAXIMUM RANGE
The maximum range and quality of
CB Transmissions very depending
on the foliowing conditions:
•The type and quality of antenna
used
•the height of the antenna’s mounting location the higher the antenna, the better the signal’s range
•the surrounding terrain mountains and tall bulinings limit the
range
•weather conditions
•Camping,fishing,and other sports
are more fun with a CB.Locate a
buddy or find out”what’s cooking”
back at camp.
•The number of neardy CBs operating on the same channel
•standing wave ratio(SWR)between
the antenna and the CB.
TRANSMISSION
COURTESY
Note: Your CB radio’s transmission
range is generally line-of –sight.
Please follow these guidelines of
redio courtesy when using your CB.
• Wait for a pause in someone else’s
transmission before you ask for a
break.
•If you do not receive an answer to
your call after a second attampt,
sign off and wait several minutes before trying again.
•Do not hold down the talk button
when you are not talking(This is
called dead keying).
•Assist callers with directions,information about road conditions,and
any other reasonable requests.
REDUCING NOISE
The Audio Clarity Enhance(ACE)circuit uses compander(compressor and
ex-pander)technology to improve
communication quality.The circuit
maintains the dymanic ragng while
increasing the signal-to-noise ratio
as the gain s automatically level.
This results in a reduction in wide band
noise.
Because your CB is exceptionally quiet,any noise you hear is probably from
13
anexternal source in you vehicle,
such as the alternator,another radio,
or spark plugs.
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 problem is in your
vehicle’s ignition or electrical system.
Here are a few hints to help you
reduce or elimintate such noise:
•Make all CB power and antenna
wires as short as possible.
•Keep the power wires away from
the antena wires.
•Be sure the chassis ground connection is secure.
•Replace old ignition wires with new,
high-voltage, noise-suppression
wires.
•Install noise suppressors on your
spark plugs, or install new spark plugs
that have built-in noise suppressors.
•lf problems persist,check your alternator/generator and regulator gauges
You can reduce the noise from these
sources by using bypass capacitors
atthe various output voltage points.
Your local RadioShack store has a
Wide selection of noise-suppression
accessories.
