You can hear police and fire departments, ambulance services, govern-

16、 ment agencies, private companies, amateur radio servic- es, aircraft, and military operations. It is legal to listen to almost every transmission your scanner can receive. However, there are some electronic and wire communi- cations that are illegal to intentionally intercept. These in- clude: Tele

17、phone conversations (cellular, cordless, or other private means of telephone signal transmission) Pager transmissions Scrambled or encrypted transmissions According to the Federal Electronic Communications Pri- vacy Act (ECPA), as amended, you could be fined and possibly imprisoned for intentionally

18、 listening to, using, or disclosing the contents of such a transmission unless you have the consent of a party to the communication (unless such activity is otherwise illegal). These laws change from time to time and there might be state or local laws that also affect legal scanner usage. 20-310.fm

25、f three sources: Internal batteries or a rechargeable scanner battery pack (not supplied see “Using Batteries”) Standard AC power (with an optional AC adapter see “Using Standard AC Power” on Page 11) Vehicle battery power (with an optional DC adapter see “Using Vehicle Battery Power” on Page 12) No

26、tes: Connecting an AC or DC adapter to the scanner dis- connects any internal batteries, but it does not dis- connect a rechargeable battery pack. If you install a rechargeable battery pack, you can operate the scanner and recharge the battery pack at the same time. See “Using Batteries” and “Chargi

27、ng a Rechargeable Battery Pack” on Page 13. If the scanner stops working properly after connect- ing it to power, try resetting it. See “Resetting/Initial- izing the Scanner” on Page 49. Using Batteries You can power your scanner from six AA batteries. For the longest operation and best performance,

28、 we recommend alkaline batteries, such as RadioShack Cat. No. 23-552. You can also power the scanner from a rechargeable scanner battery pack, such as Cat. No. 23-288. Note: You can also use six rechargeable nickel-cadmium batteries (such as Cat. No. 23-125) to power the scanner. To charge or rechar

29、ge nickel-cadmium batteries, howev- er, you must remove them from the scanner and use an external charger (such as Cat. No. 23-134). 20-310.fm Page 9 Wednesday, August 4, 1999 10:49 AM 10 Follow these steps to install batteries or a battery pack. 1. Press down on the battery compartment cover on the

30、 bottom of the scanner and slide the cover in the direction of the arrow to remove it. 2. Pull up and slide the battery holder or battery pack out of the battery compartment. 3. If you are installing individual batteries, insert six bat- teries in the battery holder as indicated by the polar- ity sy

31、mbols (+ and ) marked on the battery holder. 20-310.fm Page 10 Wednesday, August 4, 1999 10:49 AM 11 4. Slide the battery holder or battery pack into the com- partment. Caution: The battery holder or battery pack fits only one way inside the battery compartment. Do not force it. 5. Replace the cover

32、. If BATT flashes on the display, immediately replace all six non-rechargeable batteries, remove and recharge all six rechargeable batteries, or recharge the battery pack. See “Charging a Rechargeable Battery Pack” on Page 13. Caution: Always dispose of old batteries promptly and properly. Do not bu

33、ry or burn them. Using Standard AC Power To power the scanner from AC power, you need an AC adapter such as RadioShack Cat. No. 273-1665. Plug the adapters barrel plug into the scanners PWR/DC 9V jack. Then plug the adapters power module into a standard AC outlet. PWR/DC 9V 20-310.fm Page 11 Wednesd

34、ay, August 4, 1999 10:49 AM 12 Warning: Do not use an AC adapters polarized plug with an extension cord, receptacle, or other outlet unless the blades can be fully inserted to prevent blade exposure. Cautions: You must use an AC adapter that supplies 9 volts and delivers at least 300 milliamps. Its

35、center tip must be set to negative, and its plug must correctly fit the scanners PWR/DC 9V jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications could damage the scanner or the adapter. When you finish using the AC adapter, disconnect it f

36、rom the AC outlet first. Then disconnect it from the scanner. Using Vehicle Battery Power To power the scanner from your vehicles cigarette lighter socket, you need a DC Adapter, such as Cat. No. 270- 1560. Cautions: You must use a DC adapter that supplies (regulated) 9-volt power and delivers at le

37、ast 300 milliamps. Its center tip must be set to negative, and its plug must correctly fit the scanners PWR/DC 9V jack. The rec- ommended adapter meets these specifications. Using an adapter that does not meet these specifica- tions could damage the scanner or the adapter. To protect your vehicles e

38、lectrical 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. 20-310.fm Page 12 Wednesday, August 4, 1999 10:49 AM 13 1. Connect t

39、he DC adapters orange barrel plug to the adapters cable, with the tip set to (negative). 2. Set the adapters voltage switch to 9V. 3. Insert the barrel plug into the scanners PWR/DC 9V jack. 4. Plug the other end of the adapter into your vehicles cigarette-lighter socket. Note: If the scanner does n

40、ot operate properly when you connect a DC adapter, unplug the adapter from the ciga- rette-lighter socket and clean the socket to remove ashes and other debris. Charging a Rechargeable Battery Pack Your scanner has a built-in charging circuit that lets you charge a rechargeable scanner battery pack

41、(Cat. No. 23- 288, not supplied) while it is in the scanner. To charge a battery pack, simply connect an appropriate AC or DC adapter to the PWR/DC 9V jack. Note: If you want to take the battery pack out of the scan- ner to charge it, follow the instructions provided with the battery pack. It takes

42、about 14-16 hours to recharge a battery pack that is fully discharged. You can operate the scanner while re- charging the battery pack, but the charging time is length- ened. 1 2 3 4 20-310.fm Page 13 Wednesday, August 4, 1999 10:49 AM 14 Note: A rechargeable battery pack lasts longer and deliv- ers

43、 more power if you occasionally let it fully discharge. To do this, simply use the scanner until BATT appears on the display. Then fully charge the battery pack. Important! At the end of a rechargeable battery packs 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 dispos- al programs in your area. Some options that might be available are: municipa
