Uniden Sc200 Vhf Uhf Scanner Owners Manual

							CTCSS/CDCSS Operation
Your scanner is equipped with a Continuous Tone
Controlled Squelch System (CTCSS) and Continuous
Digital Controlled Squelch System (CDCSS) which allow
squelch to open only when the tone you have programmed
with a specific frequency is received along with a
transmission. When using CTCSS or CDCSS, consider the
following:

Your Scanner Scan Speed becomes slow while
Subaudible Tone function is activated.

You cannot enter CTCSS and CDCSS tones in
the AM Air Band.

If you have more questions about CTCSS or
CDCSS see What is CTCSS and CDCSS on
page 4.
Programming a CTCSS Tone/CDCSS Tone
1.Select a channel you want to program.
Note:The priority function can not be activated while
programming CTCSS/CDCSS codes. Priority may be
reactivated after storing codes.
2.Press to activate the Subaudible Tone function.
3.Press /REM.
29 
						

							At first, CTCSS tone is displayed.
If you want to change between CTCSS and CDCSS,
press .
4.Enter a tone.
a.Use VFO, or and to select the tone.
b.Then press .
Note:Press to cancel the CTCSS or CDCSS
Program Mode.
The CTCSS or CDCSS indicator and displayed
programs are turned off but not deleted.
If you want to program a no Tone, press at first,
then press .
Searching for CTCSS Tones/CDCSS Tones
You can use the CTCSS Tone Search Mode and CDCSS
Tone Search Mode to determine if the frequencies in your
area are broadcast with associated tones.
30
Change per 1sec. 
						

							Note:Subaudible tone search mode will be locked out for
channels that have been previously programmed for
subaudible tone. To perform a new subaudible tone search for
a previously programmed channel, re-program the frequency
for the channel first, and then enter subaudible tone search
mode. This is intended to prevent inadvertent reprogramming
of previously programmed channels.
Using Tone Search
1.Press .
2.To determine if a stored frequency has an associated
CTCSS tone or CDCSS tone, press when your
scanner stops on a channel.
3.Press and hold until you hear two short beeps.
CTCSSandCDCSSdisplay and begin flashing, and the
scanner starts searching for an associated CTCSS and
CDCSS tone. All tones are checked if the transmission is
long enough. If there is a break before a tone is
identified, then your scanner starts searching where it
left off when the transmission begins again.
Note:If a CTCSS or CDCSS tone has been stored in a
channel, then tone search is not available.
31 
						

							If a CTCSS tone or CDCSS tone is found, the tone
begins flashing in the display.
4.Press to program the tone with the frequency
stored in the channel.
32
Change per 1sec. 
						

							5.Repeat Steps1-4tosearch for tones associated with
other stored frequencies.
If you want to program tones for several stored
frequencies, follow these steps:

After you program a CTCSS tone or CDCSS
tone with a stored frequency, the CTCSS Tone
or CDCSS tone Search Mode is canceled. The
CTCSS or CDCSS indicator remains on but
does not flash. To activate the CTCSS Tone
Search Mode or CDCSS Tone Search Mode
again, press and hold until you hear two
short beeps.
If you decide to cancel the CTCSS Tone Search
Mode or CDCSS Tone Search Mode while
scanning, press and hold until you hear two
short beeps and the CTCSS or CDCSS indicator
turns off.

You can select the CTCSS Search Mode or
CDCSS Tone Search Mode before pressing
in Manual Mode. Simply, press and hold
until the CTCSS or DCS indicator begins
flashing, and then press .
When your scanner stops, the CTCSS Tone or
CDCSS Tone search begins immediately. If a
tone is found before the transmission ends,
press to program the tone with the
frequency stored in the channel.
Using CTCSS Tone or CDCSS Tone Search
While Searching
1.Set a Search Range.
For information about setting a search range, see Limit
Search on page 27.
2.Press and hold until you hear two short beeps.
33 
						

							CTCSSand DCS begins flashing in display.
The scanner starts searching for an associated CTCSS
tone or CDCSS tone when it stops on a transmission. All
tones are checked if the transmission is long enough.
However, if you press ,and there is break before a
tone is identified, the tone search starts where it left off
when the transmission begins again.
3.If a CTCSS tone is found, the tone begins flashing in the
display.
4.Press to program the tone with the frequency
stored in the channel.
-- OR --
Send the frequency with its associated tone to another
channel.
For information about sending a frequency to another
channel, see Programming Channels on the page 19.
5.Restart the search and repeat Steps3-4tosearch for
tones associated with other frequencies in the search
range you set in Step 1.
34 
						

							If you want to program tones for several frequencies during
your search, follow these steps:

After you program a frequency and a CTCSS
tone or CDCSS tone into a channel, the Search
Mode is changed to Search Hold Mode. To
activate the Search Mode press
/BAND.

If you decide to cancel the CTCSS Tone Search
Mode or CDCSS Tone Search Mode while you
are searching for frequencies, press and hold
until you hear two short beeps and the
CTCSS
indicator orDCSindicator turns off.
Changing a CTCSS/CDCSS Tone
1.Press to activate the Subaudible Tone function.
2.Select the channel you want to change.
3.Press .
4.Enter the new CTCSS tone or CDCSS tone using VFO
control, or .
If you make a mistake while using your keypad, press
and enter the tone again.
35
Change per 1sec. 
						

							5.Press to change the CTCSS tone.
Erasing a CTCSS/CDCSS Tone
1.Press to activate the CTCSS mode or CDCSS
mode.
2.Select the channel with the CTCSS tone or CDCSS tone
you want to erase.
36
Change per 1sec. 
						

							3.Press .
The CTCSS tone or CDCSS tone begins flashing.
4.Press or use your VFO control to select000.0.

							Remote Interface
You can communicate and program yourSC200in
numerous ways with peripheral devices using the Remote
Interface Cable port. This radio offers the following modes:

SMARTSCAN MODE
Automatically load frequencies, from the Uniden
National Frequency Database server into your
scanner using an external modem or an internal
modem included with a PC.

CLONE MODE
Clone all the frequencies of your scanner into
another
SC200.
Connecting the Scanner
Scanner to PC
Plug the smaller end of the supplied remote interface cable
into the remote port on the right side of your scanner.
When connecting the cable to your scanner, make sure the
label side of the cable is facing forward.
Plug the other end of the cable (DB-9 serial connector) into
a personal computer’s serial port. A few PC’s may require
an adapter, most will not. You may need a DB-9 to DB-25
null modem adapter, available at most computer stores. Of
course, make sure your PC is turned on.
To use SmartScan mode with an internal modem, you will
need a small custom software program to allow the serial
port to talk with the internal modem and act as a simple
“pass through”device. To download this free program, go
to Uniden’s website, look up under Scanners
“SmartScanner”or the
SC200scanner, for the
SmartScanner software. Run this program and it should
automatically set the port setting for you (although you can
override the settings). Make sure that you have a phone
line plugged into the modem jack on the back of your PC
and your scanner is connected to the serial port of the PC
using the supplied cable.
