The FCC Wants You to Know  
This scanner has been tested and found to comply with the limits for a  
scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are  
designed to provide reasonable protection against harmful interference in  
a residential installation. This scanner generates, uses, and can radiate  
radio frequency energy and, if not installed and used in accordance with  
the instructions, may cause harmful interference to radio communications.  
There is no guarantee that interference will not occur in a particular  
installation. If this scanner does cause harmful interference to radio or  
television reception, which can be determined by turning the scanner on  
and off, you are encouraged to try to correct the interference by one or  
more of the following measures:  
• Reorient or relocate the receiving antenna  
• Increase the separation between the scanner and the receiver  
This device complies with Part 15 of the FCC Rules. Operation is subject  
to the following two conditions: 1) This device may not cause harmful  
interference, and 2) this device must accept any interference received,  
including interference that may cause undesired operation.  
Scanning Legally  
Your scanner covers frequencies used by many different groups,  
including police and fire departments, ambulance services, government  
agencies, private companies, amateur radio services, military operations,  
pager services, and wireline (telephone and telegraph) service providers.  
It is legal to listen to almost every transmission your scanner can receive.  
However, there are some transmissions that you should never  
intentionally listen to. These include:  
Telephone conversations (cellular, cordless, or other private means of  
telephone signal transmission)  
• Pager transmissions  
• Any scrambled or encrypted transmissions  
According to the Electronic Communications Privacy Act (ECPA), you are  
subject to fines and possible imprisonment for intentionally listening to,  
using, or divulging the contents of such a conversation unless you have  
the consent of a party to the conversation (unless such activity is  
otherwise illegal). This scanner has been designed to prevent the  
reception of cellular telephone transmissions and the decoding of  
scrambled transmissions.  
The FCC Wants You to Know

This is done to comply with the legal requirement that scanners be  
manufactured so they are not easy to modify to pick up these  
transmissions. Do not open your scanner’s case to make any  
modifications that could allow it to pick up transmissions that are illegal to  
monitor. Modifying or tampering with your scanner’s internal components  
or using it in a way other than as described in this manual could  
invalidate your warranty and void your FCC authorization to operate it. In  
some areas, mobile and/or portable use of this scanner is unlawful or  
requires a permit. Check the laws in your area. It is also illegal in many  
areas (and a bad idea everywhere) to interfere with the duties of public  
safety officials by traveling to the scene of an incident without  
authorization.

Introduction  
15  
 
Setting Up The Scanner  
These guidelines will help you install and use your new scanner:  
• If your scanner receives interference or electrical noise, move the  
scanner or its antenna away from the source. You might also try  
changing the height or angle of the antennas.  
• Use an optional mono earphone or mono headset with proper  
impedance for private listening.  
• Do not use the scanner in high-moisture environments such as in the  
kitchen or bathroom.  
• Avoid placing the scanner in direct sunlight or near heating elements  
or vents.  
Connecting Power  
• Insert the supplied AC  
Adapter’s barrel plug into the  
power jack on the back of the  
scanner. Then plug the Adapter  
into a standard household  
outlet that supplies 120V AC,  
60Hz. Do not plug the adapter  
into a switch controlled outlet.  
• Open the battery compartment  
and insert 3 AA batteries.  
Be sure to note the polarity  
markings in the battery  
compartment. You can use  
either alkaline or rechargeable  
batteries, but the scanner will  
not recharge batteries in the  
compartment.  
• Use only fresh alkaline AA  
batteries. Rechargeable  
batteries can be used, but  
battery life is shorter than  
with alkaline batteries.  
• Always remove old or weak  
batteries. Batteries can leak  
chemicals that destroy electronic circuits.  
• Do not mix old and new batteries, different types of batteries  
(standard, alkaline, or rechargeable) or rechargeable batteries of  
different capacities.  
Setting Up The Scanner  
 
16  
Note that the batteries are intended to provide backup power for the clock  
and for scanning for a short time. When the backup batteries becomes too  
low,  
appears. Promptly replace the batteries.  
When you either install batteries or connect the AC Adapter to a standard  
US wall outlet, the scanner powers on and goes to STANDBY mode. The  
display shows the initial clock time of 12:00 AM. The scanner remains in  
STANDBY mode.  
Connecting an Antenna  
The scanner uses an  
external loop antenna to  
receive AM broadcast  
stations and an external  
telescopic antenna to  
receive all other signals.  
Connect the supplied rod  
antenna by pushing the  
antenna’s connector onto  
the antenna jack on the  
back of the scanner and  
twisting it to the desired angle. Connect the two wires from the loop  
antenna to the AM RADIO ANT terminals on the back of the scanner.  
* Carefully remove the tube inserted before using the AM  
Antenna Jack. When the Jack is not in use, keep the  
tube mounted.  
You can also use an external antenna (not supplied) to help to bring in  
weaker signals. Use RG58, 50-Ohm lead with a BNC connector to  
connect the antenna to the scanner. Connect and mount the antenna  
according to the instructions provided with the antenna.  
CAUTION: Be sure to follow all safety warnings provided with the  
antenna. Failure to do so could expose you to risk of injury or death and  
could severely damage the scanner.  
Using the Backlight  
To turn on the backlight for 15 seconds, tap SNOOZE/Backlight. To turn  
on the backlight permanently, press and hold SNOOZE/Backlight for over  
2 seconds. To turn off the backlight, press and hold SNOOZE/Backlight  
again.

Listening to AM/FM/TV Channels  
To listen to AM/FM/TV channels, slide the  
mode selector to AM/FM. Then, press the  
button at the top of the scanner to select  
the desired source (AM for AM Broadcast,  
FM1 or FM2 for FM or TV Broadcast).  
Directly Selecting a Channel  
Press SVC/DIR to select the direct entry  
mode. Use the L/M buttons to step through  
the selected band. The scanner stops on  
active channels. TV channels are scanned  
after FM channels in FM mode.  
You can also enter the channel frequency  
using the keypad, enter the channel  
frequency (for FM or AM) or the TV channel  
number and press E.  
Using AM/FM/TV Channel Memory  
Your scanner has 30 AM/FM memories for  
quick channel recall (10 for AM, 20 for  
FM/TV). To store a channel into memory, first  
select the band (AM, FM1 or FM2). Then,  
directly select the channel you want to store  
(see above). While listening to the channel,  
press and hold the number button that  
corresponds to the memory you want to save  
the channel into for 2 seconds. The scanner  
switches to the Memory mode for the current band.  
To quickly recall a channel, select the band, select the channel memory  
mode by pressing PRI/MEM, then tap the number button that  
corresponds to the memory where the channel is stored.

Using the Scanner Memories  
Your scanner has 100 memories you can  
store frequencies into for scanning. The  
memories are arranged in 10 banks of 10  
memories each. While scanning, you can  
quickly select which bank to scan by pressing  
the number button that corresponds to the  
bank you want to turn on or off for scanning.  
To select the scanner mode, slide the mode  
switch to Scanner.  
Programming Memories  
You will first need to determine the frequencies you want to program.  
This varies widely depending on what you want to listen to and your  
geographic area. There are many frequency reference sources available  
on the internet that can get you started. One such source,  
http://www.radioreference.com, has a diverse listing of many conventional  
frequencies. You might also search for regional hobbyist sites that cover  
your area or check the database at the FCC’s General Menu  
(http://www.fcc.gov) for frequencies of interest.  
Make a list of the frequencies you want to program, then organize them in  
up to 10 groups of 10 or fewer and fill out the table below. It always helps  
to plan and organize what you want to do before you start, so don’t skip  
this important step. (The numbers in the left-hand columns below  
correspond to your scanner’s memory numbers.)

Once you fill out the above chart, follow these steps to enter or change a  
frequency in a memory:  
1. Press E/PGM to enter the program mode (the scanner turns on the  
PGM icon).  
2. If the current channel is not the one you want to program, enter the  
memory number then press HOLD.  
3. Enter the frequency including the decimal point, then press E/PGM.  
4. To program the next memory, press L or M and repeat step 3. To  
program a different memory, repeat from step 2.  
5. To exit program mode, press HOLD or SCAN or change the scanner’s  
mode.  
Notes:  
• Any frequency you program replaces the previous memory contents.  
• If you enter a frequency you have already stored in a different  
memory in Step 3, the scanner beeps and displays the channel  
where you have previously stored the frequency. If you want to store  
the frequency anyway, press E/PGM a second time in Step 3.  
To clear the contents of a memory, enter “0” in Step 3.  
• Channels you program are automatically unlocked (see  
“Locking/Unlocking Memories) and have Delay turned on (See  
“Setting Channel Delay”).  
Selecting a Memory  
To select a single memory to monitor, press HOLD. The scanner turns on  
the HOLD icon. Then, select a memory by pressing L or M to go to the  
memory or input the memory number then press HOLD.  
Using the Scanner Memories

Scanning Memory Banks  
To scan the memories you have programmed, press SCAN. The scanner  
scans all unlocked programmed memories in enabled memory banks,  
stopping on a memory when it detects a transmission. To turn on/off  
memory banks while scanning, press the number button that corresponds  
to the memory bank you want to enable or disable.  
Locking/Unlocking Memories  
You can lock memories so that they are not scanned, even if their bank is  
turned on. Simply press L/O when the scanner stops on a transmission on  
the frequency or manually select the memory, then press L/O. The scanner  
turns on the L/Oicon when it is set to a memory that is locked out.  
To unlock a memory, manually select the memory, then press L/O. The scanner  
turns off the L/Oicon and includes the memory when scanning its bank.  
To unlock all memories, press and hold L/O for 2 seconds, the scanner  
beeps twice and the L/Oicon disappears.  
Using Priority Scan  
You can set one memory in each bank as a priority memory. If you turn on  
the Priority feature, the scanner will check the priority memories in enabled  
banks every 2 seconds, even if it has stopped on a transmission on  
another memory.  
To set the memory in a bank to be the priority memory, manually select the  
memory then, while holding on the memory, press E/PGM to put the  
scanner in program mode and press PRI. The scanner turns on the PRI  
icon when it is stopped on a memory designated as priority.  
To turn on Priority Scan, press PRI while the scanner is scanning or  
holding on a memory (but not in program mode). You will notice a short  
break in audio every 2 seconds as the scanner checks the enabled priority  
memories. If there is a transmission on a priority memory, the scanner will  
immediately tune to that memory.  
Setting Channel Delay  
You can set the scanner to pause for 2 seconds at the end of a  
transmission on a memory. This is useful to help prevent missed replies.  
Delay is turned on by default when you program a memory. To turn Delay  
off (or back on), first, select the channel. Then, press DELAY.  
The scanner turns on the DELAYicon for memories that have been  
programmed with delay.

Searching for Active Frequencies  
Many people enjoy searching for the unknown frequencies that are in use  
in their area but are not posted to any site or in any publication. The  
BC340CRS has two ways to search: Limit searching that searches  
between two set frequencies and Service Searching that searches for  
specific types of agencies based on the FCC’s standard frequency  
allocation for such services.  
Using Limit Search  
Programming an Upper/Lower Limit  
Follow these steps to program an Upper and Lower limit for the limit  
search:  
1. Press SEARCH then HOLD. The scanner holds on the current search  
frequency.  
2. Enter one of the range limits, then press E/PGM.  
Press L or M then enter the other range limit , and press E/PGM.  
Searching the Selected Range  
After entering the limits (or use the default limits), press SEARCH. The  
scanner starts searching from the lower range up to the higher range.  
To change the direction of the search, press L or M.  
Using Service Search  
You can select any of Police, Fire/EMS, Aircraft, Ham, and Marine  
channels for active frequencies in your area.  
Selecting a Service to Search  
Press SVC to enter the service search mode, then press the button  
corresponding to the service you want to search. When the scanner  
stops on a transmission, you can force it to resume searching by pressing  
L or M.  
Searching for Active Frequencies  
 
24  
Saving a Found Frequency into a Scan Memory  
When the scanner stops on the frequency you want to save, press HOLD  
to hold on that frequency. Then, press E/PGM. The scanner displays the  
lowest-numbered empty memory (or the last-scanned memory if all  
memories are used). Use L/M to select the memory to hold the  
frequency, then press E/PGM to store the frequency into the memory.  
Search Lockouts  
If the scanner stops on a frequency that you don’t want to hear, you can  
lock it out. When locked out, the scanner won’t stop on the frequency in  
either Limit Search or Service Search.  
Simply press L/O when the scanner stops on the frequency to lock the  
frequency out. To unlock the frequency, during search press HOLD.  
Then manually step to the frequency using the L/M keys. When you  
have selected the frequency, press L/O.  
Searching for Active Frequencies

Listening to Weather Channels  
The scanner lets you easily listen to NOAA weather channels in use in  
your area. Simply slide the audio source selector to Weather. The  
scanner scans the preset weather frequencies and stops if it detects a  
transmission. If you want to check for another frequency in use in your  
area, press SCAN or press L or M.  
Seven NOAA weather channels are available across most of the US.  
To find out which channel is in use in your area, visit their web site at  
http://www.noaa.nws.gov. The scanner also includes three Canadian  
Coast Guard weather broadcast frequencies (numbered 8-10 in the  
scanner). Select one of these frequencies if they are in use in your area.

Care and Maintenance  
General Use  
• Turn the scanner off before disconnecting the power.  
• If memory is lost, simply reprogram each channel.  
• Always press each button firmly until you hear the entry tone for that  
key entry.  
Location  
• 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 elements or  
vents.  
• If the scanner receives strong interference or electrical noise, move it  
or its antenna away from the source of the noise. If possible, a higher  
elevation might provide better reception.  
• Also try changing the height or angle of the antenna.  
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 user serviceable  
parts. Contact the Uniden Customer Service Center or take it to a  
qualified repair technician.  
Birdies  
All radios can receive “birdies” (undesired signals). If your scanner stops  
during Scan mode and no sound is heard, it might be receiving a birdie.  
Birdies are internally generated signals inherent in the electronics of the  
scanner. Press L/O to lock out the channel.  
Resetting the Scanner (Clearing all Memories)  
To reset the scanner to factory defaults, turn off the scanner. Then, while  
holding down 2, 9, and HOLD, turn on the scanner. All scanner memory  
contents are erased.
