BC244clt.qxd 3/11/99 11:59 AM Page 1 INTRODUCTION About Scanning Scanning Options Scanning is easy and fun with the BC244CLT 30-Channel Base Scanner. You can scan in 2 ways: ■ ■ Scan channels you have programmed Scan pre-programmed weather channels. What is Scanning? Unlike standard AM or FM radio stations, most 2-way communications do not transmit continuously (see Types of Communication below).
BC244clt.qxd 3/11/99 11:59 AM Page 2 You must program a frequency into each channel you want to use. If you do not have any known local frequencies to program, a Uniden representative should be able to provide you with a few sample frequencies. Where to Obtain More Information The Bearcat Radio Club and other similar hobby clubs have publications, information on computer bulletin boards, and contests for the radio enthusiast. See the enclosed printed material for more information.
BC244clt.qxd 3/11/99 11:59 AM Page 3 GETTING STARTED Installing the BC244CLT 1. Insert the small plug at the end of the AC Adapter cord into the AC 10V jack on the scanner. 2. Plug the AC Adapter into any standard 120VAC wall outlet. Do not plug into an outlet controlled by a wall switch; it could cause clock reset. 3. Plug the Telescopic Antenna into the ANT. jack. Extend the antenna to its full height. For UHF frequencies, shortening the antenna may improve the reception. 4.

BC244clt.qxd 3/11/99 11:59 AM Page 11 USING THE SCANNER Set the Squelch 1. Turn SQUELCH fully clockwise to the highest setting. 2. Press ON/OFF to turn on the scanner. 3. Adjust the VOLUME control until you can hear a steady noise.
BC244clt.qxd 3/11/99 11:59 AM Page 12 4. Set the SQUELCH control to AUTO for the factory setting. Or, manually set squelch as follows: ■ Think of squelch as a gate. Turn SQUELCH fully counter clockwise. This raises the “Squelch Gate” so high that only very strong signals can get through. ■ Turn SQUELCH fully clockwise until you hear a hiss. This lowers the “Squelch Gate” so that everything gets through — noise, weak signals, and strong signals.
BC244clt.qxd 3/11/99 11:59 AM Page 13 5. The scanner automatically starts scanning. If you have not programmed any channels yet, press WX to hear your local weather broadcast. 6. Adjust VOLUME to a comfortable listening level. Programming Tips ■ ■ ■ ■ ■ ■ ■ Program one frequency per channel. Channel 1 is the location of the default priority channel. Program the most important frequency, or the one of major interest, into Channel 1. You may also select any other channel to be the priority channel.
BC244clt.qxd 3/11/99 11:59 AM Page 14 Programming Frequencies Before you can use your BC244CLT scanner, you must program the channels (except weather frequencies). Follow these steps: Example: Program 420.150 MHz into Channel 12. 1. Press MANUAL to stop scanning. 2. To select the channel (12), press 1, then 2 on the numeric keypad. Then press MANUAL again. 3. Type in the frequency numbers, including the decimal point, using the numeric keypad: 420.0150. Channel digits flash as you make the entry.
BC244clt.qxd 3/11/99 12:00 PM Page 15 4. Press E to complete the entry. The channel digits stop flashing. Deleting a Stored Frequency If you want to delete a stored frequency, follow these steps: Example: Delete the frequency in Channel 12. 1. Press MANUAL to stop scanning. 2. To select the channel (12), press 1, then 2 on the numeric keypad. Then press MANUAL again. 3. Press 0, then E to complete the entry. The channel digits stop flashing.
BC244clt.qxd 3/11/99 12:00 PM Page 16 4. The following screen appears. About Memory Back-up Your BC244CLT has a convenient memory back-up system. In the event of a power failure, the scanner will retain channel information for an indefinite amount of time. Channel information is stored in non-volatile memory. Scanning Mode Press SCAN. (When the scanner is first turned on, it is automatically in Scan mode.) Scanning automatically stops on any active channel, except those channels locked out.
BC244clt.qxd 3/11/99 12:00 PM Page 17 Direct Channel Access This feature allows you to instantly access a specific channel you want to monitor. Example: Select Channel 4. 1. Press MANUAL to exit scan mode. 2. Press 4. When you press 4, the display changes to 4 , but the scanner still monitors the previous channel. 3. Press MANUAL again to successfully complete the direct access to Channel 4.
BC244clt.qxd 3/11/99 12:00 PM Page 18 Weather Channel Scan The BC244CLT allows you to search from 7 pre-programmed NOAA channels for your local NOAA weather channel. Press WX to find the active weather channel in your area. It is possible that your area is covered by more than one weather station. All weather channels transmit continuous broadcasts. Once the Weather Scan stops on a transmission, it remains on that channel. Weather Scan does not resume automatically.
BC244clt.qxd 3/11/99 12:00 PM Page 19 Priority Scanning Priority Scan is like a dual watch function. When you activate Priority Scan mode, the scanner keeps track of the activity on the priority channel while scanning the other channels. A constant P R I appears on the display Priority Scan mode does not operate when the scanner is in Weather mode. Every two seconds, the scanner checks the priority channel for activity.
BC244clt.qxd 3/11/99 12:00 PM Page 20 3. Press and hold PRIORITY until a beep sounds. The P R I indicator appears in the display and P indicator appears to the left of the selected channel. To enter the Priority Scan Mode When in Scan or Manual mode, press PRIORITY. The P R I indicator appears in the display. To exit the Priority Scan Mode Press PRIORITY again. The P R I indicator goes out. Channel Lockout You can lock out a channel so it is not scanned.
BC244clt.qxd 3/11/99 12:00 PM Page 21 In the Manual mode, press LOCKOUT to lock out the displayed channel. Pressing LOCKOUT does not advance to the next channel in Manual mode. L / O appears in the display to indicate the displayed channel is locked out. Whenever you want to search for channels that are locked out, press MANUAL repeatedly to go through all 30 channels. If a channel is locked out, the L / O indicator appears.
BC244clt.qxd 3/11/99 12:00 PM Page 22 Restore all Locked Out Channels To unlock all channels, you must be in Manual Mode. 1. Press MANUAL. 2. Press and hold LOCKOUT until a beep sounds. The L / O indicator goes out on any channel previously locked out.
BC244clt.qxd 3/11/99 12:00 PM Page 23 ABOUT THE UNIT Helpful Hints General Use ■ Turn the scanner off before disconnecting the power. ■ Always write down the programmed frequencies in the event of scanner memory loss. ■ If scanner memory is lost, simply reprogram each channel. The display shows All Loc Out when there has been a memory loss. ■ Always press each keypad button firmly until you hear the entry tone for that key.
BC244clt.qxd 3/11/99 12:00 PM Page 24 TROUBLESHOOTING If your BC244CLT is not performing properly, try the following steps. Problem ■ ■ ■ Scanner won’t power up. Poor reception. Scan won’t start. Solution ■ Check the connections at both ends of the AC Adapter. ■ Turn on the wall switch of your room. You could be using an outlet controlled by the wall switch. ■ Move the AC Adapter to another wall outlet. ■ Check antenna connection. ■ Move the antenna.
BC244clt.qxd 3/11/99 12:00 PM Page 25 Problem ■ ■ Scan won’t stop. Weather Scan won’t work. Solution ■ Adjust squelch to the threshold (Page 11). ■ Check the antenna connection. ■ Check to see if many of the channels are locked out. If so, the scanner has less chance of finding an active channel. ■ Review each channel’s frequency to see if it is correct and no memory has been lost. ■ It is possible that none of the programmed frequencies are active at this time.
