1、1 PSR-255 50-CHANNEL SCANNER OWNERS MANUAL 2 FEATURES Your new PSR-255 50-Channel Portable Scanner gives you direct access to over 26,000 exciting frequencies, including police and fire departments, ambulance services, and ama- teur radio services. You can select up to 50 channels to scan, and you c

2、an change your selection at any time. The secret to your scanners ability to scan so many frequen- cies is its custom-designed microprocessor - a tiny, built-in computer. Your scanner has these special features: Ten Preprogrammed Search Bands - let you search for transmissions within preset frequenc

3、y ranges, so you can find interesting frequencies more quickly. Fifty Channels - let you store up to 50 of your favorite fre- quencies for easy recall and scanning. Duplicate Frequency Check - automatically warns you if you try to store a frequency youve already stored, to help you use the scanners

4、memory more efficiently. Monitor Memory - lets you temporarily save a frequency located during a direct search, so you can move it to chan- nel storage later. Channel Lockout - keeps channels you select from being scanned. Memory Backup - keeps the channel frequencies stored in memory for about 1 ho

5、ur during a power loss. Two-Second Scan Delay - delays scanning for 2 seconds before moving to another channel, so you can hear more replies. Key Lock - lets you lock the keys to help prevent acciden- tally changing the scanners programming. Flexible Antenna with BNC Connector - provides excellent r

6、eception. The BNC connector makes it easy to attach and remove the antenna or a variety of optional antennas. Liquid Crystal Display - clearly displays how the scanner is set and makes it easy to change those settings. Three Power Options - you can power the scanner from internal batteries (not supp

7、lied - including non-rechargeable batteries, rechargeable batteries, or a rechargeable scanner battery pack) or external AC or DC power (using optional adapters). 3 Your PSR-255 scanner can receive all of these frequencies: h 26-54 MHz h 68-88 MHz h 137-174 MHz h 380-512 MHz For a list of the freque

12、A rechargeable scanner battery pack (not supplied) h Standard AC power (using an optional AC adapter) h Vehicle battery power (using an optional DC cigarette- lighter adapter) You can power your scanner from six AA batteries. For the longest operation and best performance, we recommend alkaline batt

13、eries. You can also power the scanner using a rechargeable scanner battery pack or rechargeable nickel- cadmium batteries, and recharge it as you use the scanner. Caution: Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or recharge- able batterie

14、s of different capacities. Notes: h The PWR jack lets you connect an external AC or DC adapter to operate the scanner. Connecting an adapter to PWR disconnects the internal batteries. You can use the PWR jack with either non-rechargeable or recharge- able nickel-cadmium batteries installed. h The CH

15、G jack lets you connect an external AC or DC adapter to operate the scanner. The internal batteries re- main connected when you connect an adapter to CHG, and get recharged when you connect a charger. Warning: Never use the CHG jack with non-rechargeable batteries! If you try to recharge non-recharg

16、eable batteries, they could get very hot and explode. Battery Install 1. Press down on the battery compartment cover on the bot- tom of the scanner and slide the cover in the direction to remove it. 5 2. Slide the battery holder out of the battery compartment. 3. If you are installing individual bat

17、teries, insert six AA bat- teries in the battery holder as indicated by the polarity symbols (+ and ) marked on the battery holder. 4. Slide the battery holder or battery pack into the compart- ment. Caution: The battery holder or battery pack fits only one way inside the battery compartment. Do not

18、 force it. 5. Replace the cover. When battery power is low, BATT flashes and the scanner beeps about every 3 seconds. Immediately replace all six non-rechargeable batteries or recharge the rechargeable batteries or battery pack. Caution: Always dispose of old batteries promptly and prop- erly. Do no

19、t bury or burn them. Using Standard AC Power To power the scanner from AC power, you need an AC adapter. Cautions: h You must use an AC adapter that supplies 9 volts and delivers at least 200 milliamps. Its center tip must be set to negative, and its barrel plug must correctly fit the scanners PWR/C

20、HG jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter. h When you finish using the AC adapter, disconnect it from the AC outlet first. Then disconnect it from the scanner. Plug the adapters barrel

21、 plug into the scanners PWR jack. Then plug the adapters power module into a standard AC outlet. Using Vehicle Battery Power To power the scanner from your vehicles cigarette-lighter socket, you need a DC adapter. 6 Cautions: h You must use a DC adapter that supplies 9 volts and de- livers at least

22、200 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanners PWR/ CHG jack. The recommended adapter meets these speci- fications. Using an adapter that does not meet these speci- fications could damage the scanner or the adapter. h To protect your vehicles elec

23、trical system, always plug the adapter into the scanner before you plug it into your vehicles cigarette-lighter socket. Always unplug the adapter from the vehicles cigarette-lighter socket before you unplug it from the scanner. Plug the adapters barrel plug into the scanners PWR jack. Then plug the

24、adapters power module into your vehicles cigarette-lighter socket. Charging a Rechargeable Battery Pack/ Rechargeable Batteries Your scanner has a built-in charging circuit that lets you charge a rechargeable battery pack or rechargeable nickel- cadmium batteries while it is in the scanner. To charg

25、e it, simply connect an AC or DC adapter to the scanners CHG jack. It takes about 14-16 hours to recharge a battery pack (re- chargeable batteries) that is fully discharged. You can oper- ate the scanner while recharging the battery pack (recharge- able batteries), but charging takes longer. Note: A

26、 rechargeable battery pack (rechargeable batteries) lasts longer if you let it fully discharge once a month. To do this, simply use the scanner until BATT flashes and the scan- ner beeps about every 3 seconds. Then fully charge it. Important! At the end of a rechargeable battery pack or bat- teries

27、useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste man- agement authorities for information on recycling or disposal programs in your area. Some options that might be avail- able are: municipal curb-side collection, drop-off boxes a retaile

28、rs such as your local store, recycling collection cen- ters, and mailback programs. 7 CONNECTING THE ANTENNA Follow these steps to attach the supplied flexible antenna to your scanner. 1 Align the slots around the scanners connector with the tabs on the ANT jack. 2. Press the antenna down over the j

29、ack and turn the antennas base clockwise until it locks into place. Connecting an Optional Antenna The ANT jack on the top of the scanner makes it easy to use the scanner with a variety of antennas. Instead of the sup- plied antenna, you can attach a different one, such as an external mobile antenna

30、 or outdoor base station antenna. Follow the installation instructions supplied with the antenna, route the antenna cable to the scanner, then connect it to the ANT jack. Warning: Use extreme caution when installing or removing an outdoor base station antenna. If the antenna starts to fall, let it g

31、o! It could contact overhead power lines, if the an- tenna touches a power line, contact with the antenna, mast, cable or guy wires can cause electrocution and death! Call the power company to remove the antenna. Do not attempt to do so yourself. USING THE BELT CLIP You can use the belt clip for han

32、ds-free carrying when you are on the go. Simply slide the belt clip over your belt or waistband. CONNECTING AN EARPHONE/ HEADPHONES For private listening, you can plug an earphone or mono headphones with a 3.5 mm plug into the PHONE jack on top of your scanner. This disconnects the internal speaker.

33、 Caution: To protect your hearing, follow these guidelines when you use an earphone or headphones: 8 h Do not listen at extremely high volume levels. Ex- tended high-volume listening can lead to perma- nent hearing loss. h Once you set the volume, do not increase it. Over time, your ears adapt to th

34、e volume level, so a vol- ume level that does not cause discomfort might still damage your hearing. Warning: Do not use an earphone or headphones with your scanner when operating a motor vehicle or riding a bicycle, in or near traffic. Doing so can create a traf- fic hazard and could be illegal in s

35、ome areas. CONNECTING AN EXTENSION SPEAKER In a noisy area, an extension speaker or an amplified speaker might provide more comfortable listening. Plug the speaker cables 3.5 mm plug into your scanners PHONE jack. 9 YOUR SCANNER A LOOK AT THE KEYPAD Your scanners keys might seem confusing at first b

36、ut this information should help you understand each keys function. SCAN - scans through the programmed channels. MANUAL - stops scanning to let you directly enter a channel number. BAND - selects a preprogrammed search band. MON - accesses the monitor memory. LIGHT - turns on/off the displays backli

37、ght / or / - searches down or up from the currently displayed frequency, or selects the direction when you scan channels. (key symbol) - locks/unlocks the keypad to prevent acci- dental entries. CLEAR - clears an incorrect entry. PGM - lets you program frequencies into channels. Number Keys - use th

38、ese keys to enter the numbers for a channel or frequency. DLY/. (delay/decimal point) - programs a 2-second delay for the selected channel, or enters a decimal point (necessary when programming frequencies). L-OUT/E (lockout/enter) - locks out channels so they will not be scanned, or enters frequenc

39、ies into channels. 10 A LOOK AT THE DISPLAY The display has indicators that show the scanners current operation. MAN - appears when you manually select a channel. SCAN - appears when you scan channels. MON - appears when you listen to the monitor memory. BATT - appears when battery power is low. L/O

40、 - appears when you manually select a channel you locked out. SRCH - appears during a band or direct frequency search. / or / - indicates the search or scan direction. DELAY - appears when you program a 2-seconds delay for a channel. PGM - appears while you program frequencies into the scanners chan

41、nels. (key symbol) - appears when you lock the keypad. CH - appears after the digits (1-50) that show which channel the scanner is tuned to. -d - appears during a direct frequency search. 000.000 - the digits on the right of the display show which frequency the scanner is tuned to. Error - appears w

42、hen you make an entry error. dUPL (duplicate) - appears when you try to store a frequency that is already stored in another channel. 11 UNDERSTANDING BANDS/MONITOR MEMORY Search Bands Your scanner can tune over 26,000 different frequencies. Many of these frequencies are grouped within permanent memo

43、ry locations called search bands. Band Displayed Search RangeDescription 026-40 MHzVHF Lo 140-54 MHzVHF-Lo 268-78 MHzVHF-Lo 378-88 MHzVHF-Hi 4137-144 MHzVHF-Hi 5144-146 MHz2-m Amateur Radio 6146-174 MHzVHF-Hi 7410-430 MHzUHF 8430-440 MHz70-cm Amateur Radio 9440-470 MHzUHF You can search these bands to quickly find active frequen- cies you might want to store into the scanners channels. For example, if you wanted to search for transmissions between amateur radio operators, you could search only the search bands where you are most likely to hear the transmissions (Bands 5, and 8). Not
