About Your New BC350C
The BC350C is not just a scanner. It is a brand new informa-
tion 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 six Service banks for monitoring
police, fire/emergency medical services, marine, air, weather,
and CB frequencies. Not only that, there’s even a fully pro-
grammable bank for storing your own private collection of
favorite frequencies.
With the BC350C, you can scan over 3,600 channels. In addi-
tion, the BC350C has 13 separate band search capabilities for
even greater scanning action.
Two 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!
2
What is Scanning?
Unlike standard AM or FM radio stations, most two-way com-
munications (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 para-
medics)
• NOAA weather broadcasts (8 pre-programmed 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, and 406-
512, and 806-956∗MHz ranges
∗Excluding Cellular Telephone Band
3
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
VHF FM band.
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 some-
one you want to monitor. For example, the police in your area
may broadcast 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 chan-
nel 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.
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 com-
munications.
Sharing of the available public service frequencies, or trunk-
ing, allows cities, counties, or other agencies to accommodate
hundreds of users with relatively few frequencies. Following a
conversation on a trunked system using a scanner is difficult,
if not impossible. Because when there's a short break during
the conversation you're monitoring, talkgroup will be assigned
to a completely different frequency in the trunked system.
If your local police, FIre and EMS agencies use a trunked sys-
tem and you want to be able to follow their communications,
you will want to purchase one of Unidens Trunk Trading
Scanners.
5

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.
Warning: Do not plug the AC Adapter into an outlet con-
trolled by a wall switch. This could cause scanner memory
loss.
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 anten-
na 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)

The BC350C can be mounted using the mounting bracket
(optional).
This bracket is available from the Uniden parts department
(see page 3)
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, fol-
low Steps 2 and 3. Otherwise, skip to the note following
Step 3.
2. Connect the RED wire of the DC power cord to the acces-
sory contact in your vehicle’s +13.8 VDC fuse box.
3. Connect the BLACK wire of the DC power cord to the neg-
ative side of the vehicle (usually the chassis).
Note: In vehicles with a positive ground, the RED wire con-
nects 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], [WX], [CB], or [MRN],
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 till 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
program frequencies into the channels. To program
frequencies, see "Programming Frequencies" on page xx.
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 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] Control 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.
18
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], [WX], [CB], or [MRN]. The scanner
automatically starts scanning the selected bank.
Note: Later, when you have learned how to program chan-
nels 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 disap-
pears. 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 the voice
(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.
If squelch is set on a point clockwise from the threshold,
you will hear a constant sound (noise, if no signal is pres-
ent). The scanner will not scan.
19
Scanning
To start scanning, press any bank key.
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 or [UP] 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 or WX bank). To rapidly step
through that bank, press and hold [UP] or [DOWN] key. 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], [CB] again or the [UP] or [DOWN]
keys.
Note: To resume scanning while in the Marine or Aircraft
mode, you can only press the up and down keys. Pressing
the bank key again will switch you from Marine to Air or Air to
Marine.
Note: 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 7 pre-programmed NOAA 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.

Channel Lock Out
•If the scanner beeps stopping on a particular channel due to
noise or frequent un-wanted transmissions, you may want
to keep that channel from being scanned. Usin the channel
Lock out feature will skip this channel during scanning.This
do not erase the frequency from the chanel.
•For PRIVATE bank, 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.
•In the POLICE bank, MRN bank, CB bank, or FIRE/EMS
bank, you can lock out 20, 30, 40 or ALL factory pre-
programmed channels (those frequencies that display
without channel numbers in Scan Mode). This enables you
to make a secondary private bank, if desired.
•You cannot lock out any frequency in the WX or AIR banks.
These banks are frequency search banks, and you cannot
lock out any frequency in Search Mode.
•[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.
Note: 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.
Note: It is not recommended to program a weather frequency
into any banks. Because weather channels transmit continu-
ously, the scanner will stop on that channel, disrupting the
scanning cycle. The Weather Scan feature was provided
specifically to avoid this occurrence.
21
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]. 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 20,
30, 40 or all 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.
22
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 scanning, 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 scanning.
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] /
[SEARCH].
Displaying the band range
To display the frequency band
range, press [BAND] during
search mode. 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 channel due to
noise or too frequent transmissions, you may want to lockout
or skip that frequency while searching.
To skip over a frequency, wait until the scanner stops at that
frequency. Then press the [L/O] lockout key. The scanner
immediately resumes scanning because the locked out
channel 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.
23
To restore one locked out frequency, place the scanner in the
[HOLD] mode, use [UP] or [DOWN] to find the locked out
frequency. Then press [L/O] to unlock the frequency and
place it back in the search rotation. To restore all locked out
frequencies within a bank, press and hold [L/O] key for more
than 2 seconds while in the [HOLD] mode.
24
Programming Frequencies
For POLICE, FIRE/EMS, or PRIVATE bank, you can program
one frequency per channel. Store your favorite frequencies
into the channels of each bank, one frequency per channel.
•You can program any displayed frequency on the screen.
•If you do not know any local 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. If you known
a local frequency, press [SEARCH]. Then press [BAND] to
select the band which covers that frequency. When the
search is near the frequency you want displayed on the
screen, press [HOLD] to stop searching. Then use [UP] or
[DOWN] to display the frequency you want to program.
•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.
Note: 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 xx.
25

Helpful Hints
General Use
•Turn the scanner off before disconnecting the power.
•Always write down the programmed frequencies in the
event of memory loss.
•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 sol-
vents. 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: 31.200, 41.600, and 52.000 MHz)
