About Your New BC350A
The BC350A is not
with automatic scanning capabilities. The built-in Service Scan system
brings you instantly into the exciting world of scanning action. What’s
more, you don’t even have to program the scanner to begin using it!
The BC350A comes with five Service banks for monitoring police,
fire/emergency, marine, air, and weather frequencies. Not only that,
there’s even a fully programmable bank for storing
lection
With the BC350A, you can scan almost 1,000 channels. In addition, the
BC350A has 11 separate band search capabilities for even greater scanning action.
Two Service Scan banks, POLICE and FIRE/EMG, are also programmable. 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

want to hear.
What is Scanning?
Unlike standard AM or FM radio stations, most two-way communications
(listed below) do not transmit continuously. The BC350A 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 another transmission is received.
Types of Communication
You will be able to monitor communication such as:
• Police and fire department (including rescue and paramedics)
• NOAA weather broadcasts (7 pre-programmed channels)
• 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 29-54 MHz, 137-174 MHz, and 406-512
MHz ranges

Getting Started
The following instructions apply when using your BC350A 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. Note: In case of memory loss to the scanner (indicated by "MEMO LOSS" on the display), all
settings will be lost. Memory loss occurs if the the scanner is left for a
long period of time without power.

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.
When squelch is open, you can hear the voice (scanning is

the squelch.
If squelch is set on a point clockwise from the threshold, you will
hear a constant sound (noise, if no signal is present). The scanner
will not scan.
Programming Frequencies
Before you can scan the PRIVATE bank, you must program the channels. You can program one frequency per channel. Press [PROG] to start
the Program Mode and also to complete the programming. If you do not
want to finish programming, press [BAND] to leave the Program Mode.
• You can program any displayed frequency on the screen.
• If you do not know any local frequency to program, find 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 PRIVATE bank. Note: It is recommended that you
do not program a Weather frequency into the PRIVATE bank.

Channel Lock Out
• You can lock out a channel so it is not scanned. This does not
erase the frequency from the channel when it is locked out.
• 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, or FIRE/EMG bank, you can lock
out all the 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.

Helpful Hints
General Use
• Turn the scanner off before disconnecting the power.
• Always write down the programmed frequencies in the event of
memory loss. If memory is lost, simply reprogram each channel.
The display shows "MEMO LOSS" when memory is lost.
• 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 elements or
vents.
• Do not plug the scanner into an outlet controlled by a wall switch
as prolonged periods without power will cause scanner memory
loss.
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 serviceable
parts. Contact the Uniden Customer Service Center 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-generated signals inherent in the
electronics of the receiver. If the interference is not severe, you might be
