2 FEATURES Your new RadioShack VHF/ UHF/Air Handheld Scanner lets you in on all the action! This scanner gives you di- rect access to over 23,000 exciting frequencies, includ- ing those used by police and fire departments, ambu- lance services, aircraft, transportation services, and amateur radio. You can se- lect up to 200 channels for your scanner to scan and you can change your selec- tion at any time. Your scanner also has these special features: Weather Alert — the scan- ner automatically sounds an alert when it receives a weather emergency signal. Weather Band Key — scans seven prepro- grammed weather frequen- cies to keep you informed about current weather condi- tions. Wired Programming — you can connect your scanner to a personal computer and program frequencies into thescanner from the computer using an optional cable and software. Note: The necessary cable and software, and additional information about using your personal computer to pro- gram your scanner, are available at your local Ra- dioShack store. Liquid Crystal Display — makes it easy to view and change programming infor- mation. Search Skip — lets you se- lect up to 20 frequencies for the scanner to skip during a limit or direct search to avoid unwanted frequencies. Direct Search — lets you search for a transmission starting from a specified fre- quency. Ten Channel-Storage Banks — you can store 20 chan- nels in each bank (200 total channels), letting you group channels so you can more easily identify calls. © 1999 Tandy Corporation.

3 Ten Monitor Memories — let you temporarily save up to ten frequencies you locate during a search, so you can move selected frequencies to channel storage later. Scan Delay — delays scan- ning for about 2 seconds be- fore moving to another channel, so you can hear more replies that are trans- mitted on the same channel. You can also set the scan- ner to delay on all active fre- quencies during a search. Memory Backup — keeps the channel frequencies stored in memory for an ex- tended time even if the scan- ner loses power. Three Power Options — you can power the scanner from internal (rechargeable or non-rechargeable) batter- ies or external AC or DC power (using an optional AC or DC adapter). Low Battery Alert — warns you when the battery power gets low. Key Lock — lets you lock the scanner’s keys to help prevent accidentally chang-ing the scanner’s program- ming. Key Confirmation Tones — the scanner sounds a confirmation tone when you perform an operation cor- rectly and an error tone if you make an error. Lockout Function — lets you set the scanner to ig- nore specified channels when scanning. Ten Priority Channels — let you set the scanner to check up to ten channels ev- ery 2 seconds so you do not miss important calls. Display Backlight — makes the scanner easy to read in low-light situations. Supplied Flexible Antenna with BNC Connector — provides good reception of strong local signals. You can connect an external anten- na with a BNC connector to the scanner for improved re- ception of distant/weaker signals. 20-313.fm Page 3 Friday, January 7, 2000 3:09 PM

5 FCC NOTICE Your scanner might cause radio or TV interference even when it is operating properly. To determine whether your scanner is causing the interference, turn off your scanner. If the interference goes away, your scanner is causing it. Try the following methods to eliminate the interference: • Move your scanner away from the receiver. • Connect your scanner to an outlet that is on a dif- ferent electrical circuit from the receiver. • Contact your local RadioShack store for help. Note: Mobile use of this scanner is unlawful or re- quires a permit in some ar- eas. Check the laws in your area. SCANNING LEGALLY Your scanner covers fre- quencies used by many dif- ferent groups including police and fire departments, ambulance services, govern- ment agencies, private com- panies, amateur radio services, military opera- tions, pager services, and wireline (telephone and tele- graph) service providers. It is legal to listen to almost ev- ery transmission your scan- ner can receive. However, there are some transmis- sions you should never in- tentionally listen to. These include: • telephone conversa- tions (cellular, cordless, or other private means of telephone signal transmission) • pager transmissions • any scrambled or encrypted transmissions According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprison- ment for intentionally listen- ing to, using, or divulging the 20-313.fm Page 5 Friday, January 7, 2000 3:09 PM
6contents of such a transmis- sion unless you have the consent of a party to the communication (unless such activity is otherwise illegal). This scanner is designed to prevent reception of illegal transmissions, in compliance with the law which requires that scanners be manufac- tured in such a way as to not be easily modifiable to pick up those transmissions. Do not open your scanners case to make any modifica- tions that could allow it to pick up transmissions that it is not legal to listen to. Doing so could subject you to legal penalties. We encourage responsible, legal scanner use. 20-313.fm Page 6 Friday, January 7, 2000 3:09 PM

9 PREPARATION INSTALLING BATTERIES You can power your scanner with four AA batteries (not supplied). For the best per- formance and longest life, we recommend RadioShack al- kaline batteries. Or, you can use rechargeable nickel- cadmium or nickel-metal hy- dride batteries. Both types of batteries are available at your local RadioShack store. Cautions: • The scanner has a built- in circuit that lets you recharge nickel- cadmium batteries in- side the battery com- partment. However, you must never use this cir- cuit when you have installed non- rechargeable batteries in the scanner. Be sure to read “Important Infor- mation About the Exter- nal Power Jacks” on Page 10 and “Charging Rechargeable Batter- ies” on Page 12. • Use only fresh batteries of the required size and recommended type. • Do not mix old and new batteries, different typesof batteries (standard, alkaline, or recharge- able), or rechargeable batteries of different capacities. Follow these steps to install batteries. 1. While pressing down on the tab on the bottom of the battery compart- ment cover, pull it away from the scanner to remove it. 2. Install two batteries in the battery compart- ment and two in the cover as indicated by the polarity symbols (+ and –) marked on the inside of the battery compartment and inside the cover. 20-313.fm Page 9 Friday, January 7, 2000 3:09 PM
10 3. Replace the cover. When BATT.Lo flashes and the scanner beeps every 15 seconds, or if the scanner stops operating properly, re- place or recharge the batter- ies. Warning: Dispose of old bat- teries promptly and properly. Do not burn or bury them. Caution: If you do not plan to use the scanner with batter- ies for a month or more, re- move the batteries. Batteries can leak chemicals that can destroy electronic parts. IMPORTANT INFORMATION ABOUT THE EXTERNAL POWER JACKS The scanner has two exter- nal power jacks — POWER and CHARGE. It is important that you understand the pur- pose of each jack before you connect any adapter to the scanner. The POWER jack lets you power the scanner using an external power source (AC or DC adapter). Connecting an adapter also disconnects the internal batteries. The CHARGE jack supplies power to operate the scan- ner and also charges the in- ternal batteries. Use the CHARGE jack only when you have installed rechargeable nickel-cadmium batteries. 20-313.fm Page 10 Friday, January 7, 2000 3:09 PM
