1About Your New BC350CThe BC350C is not just a scanner. It is a brand new informa-tion radio with automatic scanning capabilities. The built-inService Scan system brings you instantly into the excitingworld of scanning action. Best of all, you don’t even have toprogram the scanner to begin using it!The BC350C comes with six Service banks for monitoringpolice, 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 offavorite frequencies.With the BC350C, you can scan over 3,600 channels. In addi-tion, the BC350C has 13 separate band search capabilities foreven greater scanning action.Two Service Scan banks, POLICE and FIRE/EMS also haveprogrammable. Channels to store additional police andFire/EMS frequencies.So whenever you encounter a newly activated local frequencyfor either service category, you can add it to the bank for thatcategory. This gives you quick access to the frequencies youwant to hear.So enjoy your BC350C!
2What is Scanning?Unlike standard AM or FM radio stations, most two-way com-munications (listed below) do not transmit continuously. TheBC350C scans programmed channels at the rate of up to 100channels per second until it locates an active frequency.When scanning stops on an active frequency, it remains onthat channel as long as the transmission continues. When thetransmission ends, the scanner stays on the channel for 2more seconds, waiting for another transmission. If noresponse is detected, the scanning cycle resumes until anoth-er transmission is received.Types of CommunicationYou 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
3What is Searching?The BC350C can search each of its 13 bands to find activefrequencies. This is different from scanning because you aresearching for frequencies that have not been programmedinto your Scanner’s channels. The scanner automaticallychooses between two speeds (Search and Turbo Search)while searching. During Search Mode the scanner will search100 frequencies per second, while in Turbo Search Mode thescanner can achieve up to 300 frequencies per second in theVHF FM band.
4What is Trunk Tracking?Conventional scanning is a simple concept. You enter a radiofrequency in your scanner’s memory which is used by some-one you want to monitor. For example, the police in your areamay broadcast on 460.500 MHz, the fire department on154.445 MHz, the highway department on 37.900 MHz, etc.So when your scanner stops on a frequency, you usuallyknow who it is, and more importantly, you can stop on a chan-nel and listen to an entire conversation. This type of scanningis easy and fun.As the demand for public communications has increased,many public radio users don't have enough frequencies tomeet 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 amongthe police and fire departments and a computer systematicallyassigns 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 accommodatehundreds of users with relatively few frequencies. Following aconversation on a trunked system using a scanner is difficult,if not impossible. Because when there's a short break duringthe conversation you're monitoring, talkgroup will be assignedto 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 TradingScanners.
5Where to Obtain More InformationBefore you can scan the PRIVATE bank, you must programthe Police, Fire, EMS frequencies into the scanners channels.The Frequency Guide lists typical frequencies used aroundthe U.S.A. and Canada that you may program into your newscanner.

17Scanning OverviewYou can scan in one of three ways:1. Service Bank Scanning Press one of the six service bankkeys, [POLICE], [FIRE/EMS], [AIR], [WX], [CB], or [MRN],to find an active frequency.2. Band Search Select a frequency band to search. TheSearch function is different from scanning. It searches forany active frequency step by step within the lower andupper limits of the band. When an active frequency isfound, the scanner will stop and stay on that frequency aslong as that transmission lasts. If that frequency is interesting to you, press [HOLD] to hold the frequency inthe display. Then program it into one of the programmablebanks (PRIVATE, POLICE or FIRE/EMS). If you do notwant to program that frequency, press [SEARCH] or justwait till the transmission ends. The search resumes automatically 2 seconds after the last transmission andlooks for more active frequencies.3. PRIVATE Bank Scanning If you have programmed frequencies into this bank, press [PRIVATE] to scan onlythose that you have programmed in this bank.Note: Before you can scan the PRIVATE Bank, you mustprogram frequencies into the channels. To program frequencies, see "Programming Frequencies" on page xx.When scanning stops on an active frequency, it remains onthat channel as long as the transmission continues. When thetransmission 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 StartedThe following instructions apply when using your BC350C forthe very first time. Each time you turn on the scanner, italways retains the previous settings in its memory. That is, thescanner operates in the mode and bank last used, until youchange 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.
183. 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 scannerautomatically starts scanning the selected bank.Note: Later, when you have learned how to program chan-nels in the PRIVATE bank, you can press [PRIVATE] toscan your favorite collections.5. Adjust the volume to a comfortable listening level.Adjusting the Squelch1. 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 slightlystronger 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, toofar counterclockwise from the threshold point, a strongersignal 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.
19ScanningTo start scanning, press any bank key.When the BC350C is scanning, you can see the "SCAN" message moving across the display. Scanning stops on anyactive 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 scannerremains on the displayed channel until you press the bankkey 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 stepthrough that bank, press and hold [UP] or [DOWN] key. In theScan/Hold mode, you do not skip a locked out (L/O) channelusing [UP] or [DOWN].While scanning and the scanner stops on an active channelthat you do not want to monitor, but you do not want to lockout, 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 Aircraftmode, you can only press the up and down keys. Pressingthe bank key again will switch you from Marine to Air or Air toMarine.Note: Before you can scan the PRIVATE bank, you must program the channels.Weather Channel ScanThe BC350C allows you to search for your local NOAAweather channel.Press [WX] to find the active weather channel in your areafrom 7 pre-programmed NOAA channels. To exit WeatherMode, press any other bank key or [SEARCH].It is possible that your area is covered by more than oneweather 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.
20Channel Lock Out•If the scanner beeps stopping on a particular channel due tonoise or frequent un-wanted transmissions, you may wantto keep that channel from being scanned. Usin the channelLock out feature will skip this channel during scanning.Thisdo not erase the frequency from the chanel.•For PRIVATE bank, you can lock out all the channels in abank, if desired. However, if you do, pressing that bank keywill emit an error tone and the scanner will not scan.•In the POLICE bank, MRN bank, CB bank, or FIRE/EMSbank, 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 youto 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 cannotlock out any frequency in Search Mode.•[L/O] is active only when squelch is opened (scan isstopped) or in Hold Mode.Locking Out an Unwanted ChannelIn Scan Mode, press [L/O] when the scanner stops on achannel you do not want to hear. The scanner locks out thatchannel and immediately advances to the next channel toresume scanning.In Scan/Hold Mode, press [L/O] to lock out the displayedchannel/frequency. In this case pressing [L/O] will notadvance to the next channel. "L/O" will appear on the screento 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 remainon that channel. Weather scan will not resume automatically.You must press [WX] again to reactivate scanning. In someparts of the country, you may not be able to monitor weatherbroadcasts, such as in low-lying areas. Normally a higherlocation will improve the reception.Note: It is not recommended to program a weather frequencyinto any banks. Because weather channels transmit continu-ously, the scanner will stop on that channel, disrupting thescanning cycle. The Weather Scan feature was providedspecifically to avoid this occurrence.
21Searching for Locked Out ChannelsIn Scan Mode, you will not see locked out channels. However,to search for locked out channels and display them on thescreen, use [UP] and [DOWN]. These keys will enable you tosearch 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 ChannelSuppose you want to unlock Channel 12 of the PRIVATEbank. Press [PRIVATE] to start scanning. Press [HOLD] tostop scanning. ("HOLD" & "SCAN" must appear on thescreen.) Use [UP] or [DOWN] to find locked out Channel 12(which shows "L/O"). Then press [L/O]. "L/O" disappears toindicate that Channel 12 is now unlocked and restored forscanning.Note: For the factory pre-programmed channels, the earliestchannel will be unlocked, when you lock out more than 20,30, 40 or all channels.Restoring All Locked Out Channels1. You can unlock all locked out channels in any bank at onetime. 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 andrestored for scanning.
22Band SearchThe BC350C can search up to 13 separate frequency bandsto help you discover new and exciting frequencies in yourarea.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 anddisplays its frequency. When the conversation stops on theactive 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 willremain 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 stepthrough frequencies press and hold the [DOWN] or [UP] / [SEARCH].Displaying the band rangeTo display the frequency bandrange, press [BAND] duringsearch mode. Each time youpress [DOWN] or [UP] / [BAND],you step up or down one band range at a time. Searchingbegins automatically 3 seconds after the band range is displayed (or you can press [SEARCH] to start searching).Frequency LockoutIf the scanner keeps stopping on a particular channel due tonoise or too frequent transmissions, you may want to lockoutor skip that frequency while searching.To skip over a frequency, wait until the scanner stops at thatfrequency. Then press the [L/O] lockout key. The scannerimmediately 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 41stL/O frequency entered causes the 1st locked out frequency tobecome unlocked.
23To 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 andplace it back in the search rotation. To restore all locked outfrequencies within a bank, press and hold [L/O] key for morethan 2 seconds while in the [HOLD] mode.
24Programming FrequenciesFor POLICE, FIRE/EMS, or PRIVATE bank, you can programone frequency per channel. Store your favorite frequenciesinto 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 activefrequency by scanning any service bank or searching anyselected band. Then, when you find a desired frequency,program that frequency to the bank. •You can also program a non-active frequency. If you knowna local frequency, press [SEARCH]. Then press [BAND] toselect the band which covers that frequency. When thesearch is near the frequency you want displayed on thescreen, 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, orWX.Note: It is recommended that you do not program a Weatherfrequency 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 onhow to obtain these frequencies can be found "where toobtain more information" on page xx.
25Programming from SCAN modeFor example, when you find an interesting active police frequency while scanning, and want to program it into yourprivate bank (see "SCANNING" on page xx) to scan the bank:1. Press [HOLD].HOLD appears on the display.2. Press [PROG]. CH appearsand blinks to indicate that youare in the Programming Mode.To change the displayed fre-quency, use [UP] or [DOWN]while CH is blinking.3. Press [PRIVATE]. PRIVATEappears on the display.If you want to program it intoanother bank, press thedesired bank key. The bankname appears on the display.2 screens alternate to indicatethat Channel 1 is available tobe programmed.The scanner automaticallyselects the lowest open channel (000.0000) for easyprogramming. If all channelshave been programmed (thereare no open channels in thebank), channel 1 appears.Use the [UP] or [DOWN] keysto select a new channel andeven over write old channels.4. Press [PROG] to store the frequency in the desired channel.Note: Press [BAND] to escapefrom programming mode beforestep 4.
26Programming from SEARCH mode.For example, when you find an interesting active police fre-quency while searching 144 - 148 band, and want to programit into POLICE bank (see "Band Search" on page xx to searcha frequency).1. Press [HOLD]. HOLD iconappears in the display.2. Press [PROG]. CH appearsand blinking to indicate thatyou are in the programmingmode.3. Press [POLICE]. POLICE iconappears in the display.If you want to program it intoanother bank, press thedesired bank key. The bankname appear on the display.2 screens alternate to indicatethat channel 1 is available tobe programmed.The scanner automaticallyselects the lowest open channel (000.0000) for easyprogramming. If all channelshave been programmed (thereare no open channels in thebank), channel 1 appears.Use the [UP] or [DOWN] keysto select a new channel andeven over write old channels.4. Press [PROG] to store the frequency in the desired channel.Note: Press [BAND] to escapefrom programming mode beforestep 4.
27Deleting a programmed frequency (programming "000.0000")You can erase a programmed frequency in a channel by programming "000.0000" into its channel. You can find anddisplay "000.0000" on the screen in one of two ways:Find an open channel in the private bank. Press the desiredbank key (PRIVATE, POLICE, or FIRE/EMS) then [HOLD],and use [UP] and [DOWN] to scroll through the bank to findan open channel, "000.0000" – OR –Find "000.0000" from the Search & Program Mode. Everysearch band has one "000.0000" display included betweenthe band limits. It can be displayed only in the Program Mode(after pressing [PROG] and "CH" is blinking in the display).Note: Press [BAND] to escape from programming modebefore step 4.
28To find "000.0000" in any Search Band1. Select Search Band 50 - 54 by pressing [BAND] in theSearch ode, for example band 50-54.2. Press [HOLD] to stop searching.3. Press [PROG] to go into Program Mode.4. Use [UP] and [DOWN] to display "50.0000" or "54.0000".5. Press [DOWN] one time at the "50.0000" screen to display"000.0000"– OR –For example to erase a programmed frequency in channel 13of the PRIVATE BANK:Program Lock FeatureThe BC350C has a program lock feature [Memory Lock] toprevent accidental programming entries or unauthorized pro-gramming. Simply turn on the MEMO LOCK switch on therear panel to disable [PROG] and protect your programmedfrequencies in memory.1. Find this screen in the programming Mode.2. Press [PRIVATE]. PRIVATEappears in the display.2 screens alternate to indicatethat Channel 1 is ready to beprogrammed.3. Use [UP] or [DOWN] to selectChannel 13.Now, Channel 13 is ready tobe programmed.4.

29Helpful HintsGeneral Use•Turn the scanner off before disconnecting the power.•Always write down the programmed frequencies in theevent of memory loss.•Always press each keypad button firmly until you hear theentry tone for that key entry.Location•If strong interference or electrical noise is received, relocatethe scanner or its antenna away from the source of thenoise. A higher elevation, if possible, may provide betterreception. You might also try changing the height or angle ofthe telescoping antenna.•Do not use the scanner in high-moisture environments suchas 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.BirdiesAll radios are subject to receiving undesired signals or birdies.If your scanner stops during SEARCH mode and no sound isheard, it may be receiving a birdie. Birdies are internally-gen-erated signals inherent in the electronics of the receiver. If theinterference is not severe, you might be able to turn [SQ]counterclockwise to cut out the birdie. Or, press [SEARCH] toresume searching. (Known birdie frequencies for the BC350Care: 31.200, 41.600, and 52.000 MHz)
