About Your New BC350C
The BC350C is not just a scanner. It is a brand new
information radio with automatic scanning capabilities. The
built-in Service Scan system brings you instantly into the
exciting world of scanning action. Best of all, you don’t even
have to program the scanner to begin using it!
The BC350C comes with 6 Service banks for monitoring
police, fire/emergency medical services, marine, air, weather,
and CB frequencies. Not only that, there’s even a fully
programmable bank for storing your own private collection of
favorite frequencies.
With the BC350C, you can scan over 3,600 channels. In
addition, the BC350C has 13 separate band search
capabilities for even greater scanning action.
2 Service Scan banks, Police and Fire/EMS also have
programmable channels to store additional police and
Fire/EMS frequencies. So whenever you encounter a newly
activated local frequency for either service category, you can
add it to the bank for that category. This gives you quick
access to the frequencies you want to hear.
So enjoy your BC350C!

What is Scanning?
Unlike standard AM or FM radio stations, most two-way
communications (listed below) do not transmit continuously.
The BC350C scans programmed channels at the rate of up to
100 channels per second until it locates an active frequency.
When scanning stops on an active frequency, it remains on
that channel as long as the transmission continues. When the
transmission ends, the scanner stays on the channel for 2
more seconds, waiting for another transmission. If no
response is detected, the scanning cycle resumes until
anoth-er transmission is received.
Types of Communication
You will be able to monitor communication such as:
•
Police and fire departments
(including rescue and paramedics)
•
NOAA weather broadcasts (10 pre-programmed channels,
2 are Canadian Marine Weather Channels)
•
•
•
•
•
Citizens Band (CB)
Business/industrial radio
Motion picture and press relay
Utility
Land transportation frequencies, such as trucking firms,
buses, taxis, tow trucks, and railroads
•
•
•
Marine and amateur (ham radio) bands
Air band
And many more in the 25-54 MHz, 108-174 MHz,
∗
406-512, and 806-956 MHz ranges
∗ Excluding Cellular Telephone Band

What is Searching?
The BC350C can search each of its 13 bands to find active
frequencies. This is different from scanning because you are
searching for frequencies that have not been programmed
into your scanner’s channels. The scanner automatically
chooses between two speeds (Search and Turbo Search)
while searching. During Search Mode the scanner will search
100 frequencies per second, while in Turbo Search Mode the
scanner can achieve up to 300 frequencies per second in the
5 kHz step band.

UB317Z (BC350C) 0916 9/16/03 12:42 PM Page 4
What is Trunk Tracking?
Conventional scanning is a simple concept. You enter a radio
frequency in your scanner’s memory which is used by
someone you want to monitor. For example, the police in your
area may transmit on 460.500 MHz, the fire department on
154.445 MHz, the highway department on 37.900 MHz, etc.
So when your scanner stops on a frequency, you usually
know who it is, and more importantly, you can stop on a
channel and listen to an entire conversation. This type of
scanning is easy and fun.
As the demand for public communications has increased,
many public radio users don't have enough frequencies to
meet their needs, and this has created a serious problem.
Trunking radio systems have been implemented to solve this
problem.
In a trunked radio system the frequencies are shared among
the police and fire departments and a computer systematically
assigns available frequencies when they are needed for
communications.
Sharing of the available public service frequencies, or
trunking, allows cities, counties, or other agencies to
accommodate hundreds of users with relatively few
frequencies. Following a conversation on a trunked system
using a convertional scanner is difficult, if not impossible.
Because when there's a short break during the conversation
you're monitoring, a completely different frequency will be
assigned within the trunked system when the conversation
resumes.
If your local police, fire, and EMS agencies use a trunked
system and you want to be able to follow their
communications, you will want to purchase one of Uniden’s
Trunk Tracking Scanners.

Installing the BC350C
For Home Use (Desktop Installation)
1. Insert the DC plug end of the AC Adapter into the DC
13.8V jack on the rear panel.
2. Plug the AC Adapter into a standard 120V AC wall outlet.
3. Plug the Telescoping Antenna into the ANT connector.
Extend the antenna to its full height. For frequencies
higher than 406 MHz, shortening the antenna may improve
the reception.
4. Use the desktop stand for a better viewing and operating
angle.
Helpful Hints
• If strong interference or electrical noise is received, relocate
the scanner or its antenna away from the source.
• If you are operating the scanner in a fringe area or need to
improve reception, use an optional antenna designed for
multi-band coverage. (You can purchase this type of
antenna at a local electronics store.)
• If the optional antenna has no cable, use 50-70 ohm coaxial
cable for lead-in. A mating plug may be necessary for the
optional antennas.
For Mobile Use (In-Car Installation)
Installation for Temporary Use:
A Cigarette Lighter Power Cord is provided for easy,
temporary installation.
Warning: Do not use the cigarette lighter power cord in a
positive ground vehicle.
Plug one end of the Cigarette Lighter Power Cord into the

Connecting the Antenna Plug
Connect the mobile antenna plug into the ANT connector on
the rear panel. (For more information on antenna installation,
please refer to the instruction guide that came with your
antenna.)
Mounting the Radio for Everyday Use
The BC350C can be mounted using the mounting bracket
(optional).
This bracket is available from the Uniden parts department
(see page 5)
1. Select an ideal location in your vehicle to mount the
BC350C. Avoid a location that could interfere with your
driving. In a passenger car, the ideal location is underneath
the dashboard on the passenger side.
2. Use the mounting bracket (optional) as a template for
marking the location of the mounting screws.
Note: If there are screws already holding the dashboard, you
can use the same screw holes to mount the bracket.
3. Drill the necessary holes and secure the mounting bracket
in place using the screws provided.
4. Mount the radio to the bracket only after the wiring has
been connected to the rear panel.
Connecting the Power Cord
Note: If you are not experienced in connecting accessories to
the vehicle fuse box, please see your automotive dealer for
advice on proper installation.
Installation for Everyday Use:
1. Check the vehicle battery connections to determine which
battery terminal (positive or negative) is grounded to the
engine block or chassis. Most of today’s vehicles use a
negative ground. If your vehicle has a negative ground,
follow Steps 2 and 3. Otherwise, skip to the note following
Step 3.
2. Connect the RED wire of the DC power cord to the
accessory contact in your vehicle’s +13.8 VDC fuse box.
3. Connect the BLACK wire of the DC power cord to the
negative side of the vehicle (usually the chassis).
Note: In vehicles with a positive ground, the RED wire
connects to the chassis and the BLACK wire connects to
the accessory contact in the fuse box.
4. Insert the DC plug into the DC 13.8V jack on the back of
the scanner.

Scanning Overview
You can scan in one of three ways:
1. Service Bank Scanning Press one of the six service bank
keys, [POLICE], [FIRE/EMS], [AIR/MRN], [WX], or [CB]
to find an active frequency.
2. Band Search Select a frequency band to search. The
Search function is different from scanning. It searches for
any active frequency step by step within the lower and
upper limits of the band. When an active frequency is
found, the scanner will stop and stay on that frequency as
long as that transmission lasts. If that frequency is
interesting to you, press [HOLD] to hold the frequency in
the display. Then program it into one of the programmable
banks (Private, Police or Fire/EMS). If you do not want to
program that frequency, press [SEARCH] or just wait untill
the transmission ends. The search resumes automatically
2 seconds after the last transmission and looks for more
active frequencies.
3. PRIVATE Bank Scanning If you have programmed
frequencies into this bank, press [PRIVATE] to scan only
those that you have programmed in this bank.
Note: Before you can scan the Private bank, you must pro-
gram frequencies into the channels. To program
frequencies, see "Programming Frequencies" on page 24.
When scanning stops on an active frequency, it remains on
that channel as long as the transmission continues. When the
transmission ends, the scanner will remain on the same
channel for 2 more seconds, waiting for a responding
transmission. If there is no responding transmission within 2
seconds, the scanning cycle resumes.
Getting Started
The following instructions apply when using your BC350C
(except for in the Program mode) for the very first time. Each
time you turn on the scanner, it always retains the previous
settings in its memory. That is, the scanner operates in the
mode and bank last used, until you change the settings.
1. Turn the Squelch [SQ] fully clockwise to the end.
2. Power on the scanner by turning [VOLUME] clockwise.
Adjust the volume to where you can hear a steady noise.

3. Set the squelch at the scanning threshold by turning [SQ]
counterclockwise just until the noise disappears.
4. Press any of the Service bank keys: [POLICE],
[FIRE/EMS], [AIR/MRN], [WX], or [CB]. The scanner
automatically starts scanning the selected bank.
Note: Later, when you have learned how to program
channels in the Private bank, you can press [PRIVATE] to
scan your favorite collections.
5. Adjust the volume to a comfortable listening level.
Adjusting the Squelch
1. Open the squelch by turning [SQ] clockwise to the end.
You should hear a steady sound (scanning stops).
2. Turn [SQ] counterclockwise slowly until the sound
disappears.
This is the threshold point at which scanning starts.
At the squelch threshold, an incoming signal just slightly
stronger than the noise will open the squelch.
Note: When squelch is open, you can hear a voice or
hissing if squelch is set too low and there is no
transmission (scanning is stopped). If squelch is set too
tight, that is, too far counterclockwise from the threshold
point, a stronger signal is required to open the squelch.

Scanning
To start scanning, press any bank key: [POLICE],
[FIRE/EMS], [AIR/MRN], [WX], [CB], or [PRIVATE] keys.
When the BC350C is scanning, you can see the "SCAN"
message moving across the display. Scanning stops on any
active channel automatically and displays its frequency,
except those channels programmed with L/O (Lock Out).
Scanning resumes when you press the bank key or [UP] key.
To stop scanning at any time, press [HOLD]. When you press
[HOLD], you are in the Scan/Hold Mode. The scanner
remains on the displayed channel until you press the bank
key again to resume scanning. (Or, you can press [SEARCH]
to start searching.)
In the Scan/Hold Mode, each time you press [UP] or
[DOWN], you step up or down one channel at a time (one
frequency step each for the AIR bank). To rapidly step
through that bank, press and hold [UP] or [DOWN]. In the
Scan/Hold Mode, you do not skip a locked out (L/O) channel
using [UP] or [DOWN].
While scanning and the scanner stops on an active channel
that you do not want to monitor, but you do not want to lock
out, you can simply press the bank key: [PRIVATE],
[POLICE], [FIRE/EMS], [WX], or [CB] again or [UP].
Notes: • To resume scanning while in the Marine or Aircraft
mode, you can only press [UP]. Pressing the bank
key again will switch you from Marine to Air or Air
to Marine.
• Before you can scan the Private bank, you must
program the channels.
Weather Channel Scan
The BC350C allows you to search for your local NOAA
weather channel.
Press [WX] to find the active weather channel in your area
from 10 pre-programmed channels. To exit Weather Mode,
press any other bank key or [SEARCH].
It is possible that your area is covered by more than one
weather station.
When you press [WX], the BC350C will find an active broad-
cast immediately. If the broadcast sounds weak and distant,
press [WX] again to look for a closer station.

UB317Z (BC350C) 0916 9/16/03 12:43 PM Page 20
Notes: • All weather channels transmit continuous
broadcasts.
Once the Weather scan stops on a transmission, it
will remain on that channel. Weather scan will not
resume automatically.
You must press [WX] again to reactivate scanning.
In some parts of the country, you may not be able
to monitor weather broadcasts, such as in
low-lying areas. Normally a higher location will
improve the reception.
• It is not recommended to program a weather
frequency into any banks. Because weather
channels transmit continuously, the scanner will
stop on that channel, disrupting the scanning cycle.
The Weather Scan feature was provided
specifically to avoid this occurrence.
Channel Lock Out
• If the scanner stops on a particular channel due to noise or
frequent un-wanted transmissions, you may want to keep
that channel from being scanned. Using the channel Lock
out feature will skip this channel during scanning.This does
not erase the frequency from the channel.
• For programmable channels, you can lock out all the
channels in a bank, if desired.
However, if you do, pressing that bank key will emit an error
tone and the scanner will not scan (for Private bank).
• In the Police bank, MRN bank, CB bank, or Fire/EMS bank,
you can lock out 30 factory pre-programmed
channels (those frequencies that display without channel
numbers in Scan Mode).
• You cannot lock out any frequency in the WX or AIR banks.
• [L/O] is active only when squelch is opened (scan is
stopped) or in Hold Mode.
Locking Out an Unwanted Channel
In Scan Mode, press [L/O] when the scanner stops on a
channel you do not want to hear. The scanner locks out that
channel and immediately advances to the next channel to
resume scanning.
In Scan/Hold Mode, press [L/O] to lock out the displayed
channel/frequency. In this case pressing [L/O] will not
advance to the next channel. "L/O" will appear on the screen
to indicate that the displayed channel is locked out.

Searching for Locked Out Channels
In Scan Mode, you will not see locked out channels.
However, to search for locked out channels and display them
on the screen, use [UP] and [DOWN] in Scan/Hold Mode.
These keys will enable you to search manually through the
bank in Hold Mode only. " L/O " will appear on the screen to
indicate the locked out channel.
Restoring a Locked Out Channel
Suppose you want to unlock Channel 12 of the Private
bank. Press [PRIVATE] to start scanning. Press [HOLD] to
stop scanning. ("HOLD " & " SCAN " must appear on the
screen.) Use [UP] or [DOWN] to find locked out Channel 12
(which shows "L/O"). Then press [L/O]. "L/O" disappears to
indicate that Channel 12 is now unlocked and restored for
scanning.
Note: For the factory pre-programmed channels, the earliest
channel will be unlocked, when you lock out more than 30
channels.
Restoring All Locked Out Channels
1. You can unlock all locked out channels in any bank at one
time. Press a bank key to start scanning.
2. Press [HOLD] to stop scanning.
3. Press and hold down [L/O] ("L/O" appears on the screen)
for more than 2.5 seconds until you hear the multi-beep
("L/O" disappears).
Now all locked out channels in the bank are unlocked and
restored for scanning.

Band Search
The BC350C can search up to 13 separate frequency bands
to help you discover new and exciting frequencies in your
area.
To start searching, press [SEARCH].
Searching starts from the frequency most recently used.
Press [UP] or [DOWN] to change the searching direction.
Searching stops on any active frequency automatically and
displays its frequency. When the conversation stops on the
active frequency, the scanner will resume searching for
another active channel.
If you want to monitor a specific conversation, press [HOLD]
to place the scanner in Hold Mode. The scanner will remain
on the frequency displayed until you press [SEARCH] or
[BAND] to resume searching.
In the Hold Mode, each time you press [DOWN] or [UP], you
step up or down one frequency at a time. To rapidly step
through frequencies press and hold the [DOWN] or [UP].
Displaying the Band Range
To display the frequency band
range, press [BAND]. Each time
you press [DOWN] or [UP] /
[BAND], you step up or down
one band range at a time. Searching begins automatically 3
seconds after the band range is displayed (or you can press
[SEARCH] to start searching).
Frequency Lockout
If the scanner keeps stopping on a particular frequency due
to noise or too frequent transmissions, you may want to
lockout that frequency while searching.
To skip over a frequency, wait until the scanner stops at that
frequency. Then press [L/O]. The scanner immediately
resumes searching because the locked out frequency is no
longer in the searching sequence.
Note: You can program up to 40 L/O frequencies. The 41st
L/O frequency entered causes the 1st locked out frequency to
become unlocked.

Programming Frequencies
For the Police, Fire/EMS, or Private bank, you can store your
favorite frequencies into the channels of each bank, one fre-
quency per channel.
• You can program any displayed frequency on the screen.
• If you do not know any local frequencies you can search for
an active frequency by scanning any service bank or
searching any selected band. Then, when you find a
desired frequency, program that frequency to the bank.
• You can also program a non-active frequency through the
search mode.
• You cannot program a frequency into Air, MRN, CB, or WX.
Note:
• It is recommended that you do not program a Weather
frequency into the Private bank.
• In order to program the Private channels in your scanner
you must obtain the frequencies of the agencies (Police,
Fire, EMS, etc.) you want to monitor. Information on how to
obtain these frequencies can be found "Where to Obtain
More Information" on page 5.

Helpful Hints
General Use
• Turn the scanner off before disconnecting the power.
• Always press each keypad button firmly until you hear the
entry tone for that key entry.
Location
• If strong interference or electrical noise is received, relocate
the scanner or its antenna away from the source of the
noise. A higher elevation, if possible, may provide better
reception. You might also try changing the height or angle
of the telescoping antenna.
• Do not use the scanner in high-moisture environments such
as the kitchen or bathroom.
• Avoid placing the unit in direct sunlight or near heating
ele-ments or vents.
Cleaning
• Disconnect the power to the unit before cleaning.
• Clean the outside of the scanner with a mild detergent.
• To prevent scratches, do not use abrasive cleaners or
solvents. Be careful not to rub the LCD window.
• Do not use excessive amounts of water.
Repairs
• Do not attempt any repair. The scanner contains no
service-able parts. Contact the Uniden Customer Hotline at
1-800-297-1023 or take it to a qualified repair technician.
Birdies
All radios are subject to receiving undesired signals or birdies.
If your scanner stops during Search Mode and no sound is
heard, it may be receiving a birdie. Birdies are internally-gen-
erated signals inherent in the electronics of the receiver. If the
interference is not severe, you might be able to turn [SQ]
counterclockwise to cut out the birdie. Or, press [SEARCH] to
resume searching. (Known birdie frequencies for the BC350C
are: 108.785, 462.5625, 485.9, 814.0, 932.825, 938.375, and
940.9 MHz)
