							Scanning Overview
You can scan in one of three ways:
·Service Bank Scanning  Press one of the five service bank keys, 
[POLICE], 
[FIRE/EMG], 
[AIR], 
[WX] or 
[MRN], to find an active
frequency.
·Band Search  Select a frequency band to search.  The Search
function is different from scanning.  It searches for any active fre-
quency 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 fre-
quency 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/EMG).  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.
·
PRIVATE Bank Scanning  If you have programmed frequencies
into this bank, press 
[PRIVATE] to scan only those that you have
programmed in this bank.
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 BC350A for the very
first time.  Each time you turn on the scanner, it always retains the pre-
vious 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 mem-
ory 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.
1. Turn the Squelch 
[SQ] Control fully clockwise to the end.
2. Power on the scanner by turning 
[VOLUME] clockwise.  Adjust the vol-
ume to where you can hear a steady noise.
3. Set the squelch at the scanning threshold by turning 
[SQ] counterclock-
wise just until the noise disappears.
13 
						

							4. Press any of the Service bank keys:  [POLICE], [FIRE/EMG], [AIR],
[WX], or [MRN].  The scanner automatically starts scanning the se-
lected bank.
Note:
  Later, when you have learned how to program channels 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 disappears.  This is
the threshold point at which scanning starts.  At the squelch thresh-
old, 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 counterclock-
wise 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 present).  The scanner
will not scan.
Programming Frequencies
Before you can scan the PRIVATE bank, you must program the chan-
nels. 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 fre-
quency to the PRIVATE bank.  Note:  It is recommended that you
do not program a Weather frequency into the PRIVATE bank.
14 
						

							·You can also program a non-active frequency.  If you known a lo-
cal 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 fre-
quency you want to program.

Program Lock Feature
The BC350A has a program lock feature [Memory Lock] to prevent acci-
dental programming entries or unauthorized programming.  Simply turn
on the MEMO LOCK switch on the rear panel to disable [PROG] and pro-
tect the memory.

							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 scan-
ner 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 en-
ables 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 ad-
vances to the next channel to resume scanning.
In Scan/Hold Mode, press [L/O]
 to lock out the displayed channel/fre-
quency.  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.
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 dis-
appears to indicate that Channel 12 is now unlocked and restored for
scanning.
18 
						

							Restoring All Locked Out Channels
You can unlock all locked out channels in any bank at one time.  To do
this, first press a bank key to start scanning.  Then press [HOLD] to stop
scanning.  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.
A Word About Memory Back-up
Your BC350A has a convenient type of memory back-up system.  In the
event of a power failure, the scanner provides approximately 30 days of
memory retention so you don’t immediately lose the frequencies you
stored in any of the channels. 
19 
						

							Scanning
To start scanning, press any bank key.
When the BC350A is scanning, you can see the 
SCAN message mov-
ing across the display.  Scanning stops on any active channel automat-
ically and displays its frequency, except those channels programmed with
L/O (Lock Out).  Scanning resumes automatically two seconds after the
channel becomes inactive.
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 any bank 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).  Press and hold 
[UP] or 
[DOWN] to rapidly step through
that bank.  In the Scan/Hold mode, you do not skip a locked out (L/O)
channel using 
[UP] or 
[DOWN].
Weather Channel Scan
The BC350A allows you to search for your local NOAA weather channel.
Press 
[WX] to find the active weather channel in your area from 7 pre-pro-
grammed 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 BC350A will find an active broadcast immedi-
ately.  If the broadcast sounds weak and distant, press 
[WX] again to
look for a closer station.
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 continuously, the scanner
will stop on that channel, disrupting the scanning cycle.  The Weather
Scan feature was provided specifically to avoid this occurrence.
