							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!

							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 Scanning?

							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.

What is Searching?
UB317Z (BC350C) 0916  9/16/03  12:42 PM  Page 3 
						

							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 dont 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 theres a short break during the conversation
youre 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.

							Before you can scan the Private bank, you must program the
police, fire, EMS, or other interesting frequencies into the
Scanners Channels.
The Frequency Guide lists typical frequencies used around
the U.S.A. and Canada that you may program into your new
scanner. However, this is not a complete list of frequencies for
your area.
