The Basics 4 The FCC wants you to know This equipment has been tested and found to comply with th e limits for a Class B digital device, purs uant to Part 15 of the FCC Rules . These limits are designed to provide reasonable protection against harmful interference in a residential installation .
5 The Basics powering your scanner Y ou can power your scanner from any of three sources: • internal batteries ( not supplied) • standard A C power (using an optional AC adapter) • vehicle batte.
The Basics 6 Install 2 AA batteries, matching the polarity symbols (+ -). Replace the cover ..
7 The Basics Wa r n i n g : Set ALK ALINE/RECHARGEABLE to RECHARGEABLE for use only with nickel cadmi um (Ni-Cd) or nickel metal hy dride (Ni-MH) rechargeable batteries. Never attempt to re charge non- rechargeable batteri es. Non-rechargeable batteries can get hot or explode if you try to recharge them.
The Basics 8 RECHARGEABLE inside the battery compartment to RECHARGEABLE , install the batteries in the scan ner , and connect an external AC or DC adapter to the scanner's DC 6V jack (see “using A C power ” on P age 10 or “using vehicle battery power ” on P age 11).
9 The Basics • If you connect an external power source to the scanner with ALK ALINE/RECHARGEABLE set to ALK ALINE , CHArg appears but the scanner does NO T ch arge the batteries. Th is is because the scanner's microprocessor unit does not recognize the sw itch position when you incorrectly connect an external power source .
The Basics 10 using A C power Y ou can power the scanner using a 6V , 300 mA AC adapter and a size B Adaptapl ug™ adapter (neither supplied). Both are ava ilable at yo ur local RadioShack store. Cautions: • Y ou must use a Class 2 power source that supplies 6V DC and delivers at least 300 mA .
11 The Basics using vehicle battery power Y ou can power the scanner from a vehicle's 12V power source (such as a cigarette-lighter socket) using a 6V , 300 mA DC adapter and a size B Adaptaplug (neither supplied). Both are available at your local RadioShack store.
The Basics 12 If rechargeable batteries are installed and ALK ALINE/RECHARGEABLE is s et to RECHARGEABLE , the adapter powers the scanner and recharges the installed batteries at the same time.
13 The Basics setting up your scanner connecting the antenna T o attach the supplied flexible antenna to the connector on the top of your scanner , al ign the slots around the antenna's conne ct or with the tabs on the scanner's BNC connector .
The Basics 14 Note: Always use 50- ohm, RG-58, or RG-8 , coaxial cable to connect an outdoor antenna. If the antenna is more than 50 feet from the scanner , use RG-8 low - loss dielectric coaxial cable. If your antenna's cable does not have a BNC connector , your local RadioShack store carries a var iety of BNC adapters.
15 The Basics • Once you set the volume, do not increase it. Over time, your ears adap t to the volume level, so a volume level that does not cause discom- fort might still damage your hearing . traffic safety Do not use an earphone or headphones with your scanner when operating a motor vehicle in or near traffic.
The Basics 16 attaching the belt clip T o make your scanner easier to carry when you are on the go, use the supplied belt clip. Use a Phillips screwdriver a nd the supplied scre ws to attach the clip to the scanner .
17 The Basics about your scanner W e use a few simple terms in this manual to explain the features of the scanner . F amiliarize yourself with these terms and the scanner's features, and you can put the scanner to work for you right away .

The Basics 22 a look at the display The display has indicators that show the scanner's current operating status. The display i nformation helps you understand how your s canner operates. BANK - appears with numbers (1-10). P - appears when you select a priority channel.
23 The Basics L/O - appears when you manually select a channel you locke d out or a skip frequ ency . - appears when you lock the keypad. - alerts you when the battery power gets low . PGM - appears while you store a frequency into a channel. or - appears during search mode.
The Basics 24 understanding banks ser vice banks The scanner is preprogrammed with all the frequen- cies allocated to the weather , ham, marine, aircraft , and police (fire/emergency) services.
25 Beyond the Basics operating your scanner turning on th e scanner and setting squelch Y our scanner is preprogrammed at the factory with 150 of the most frequently used frequencies in Channels 1 to 150. Y ou can scan these frequencies as soon as you turn on the scanner .
Beyond the Basics 26 consider using a frequency guide. Excellent refer- ences for active frequencies are the RadioShack P olice Call Guide including Fir e and Emergency Services, and Official Aeronautical F requency Direc- tory . W e update these dire ctories every year , so be sure to get a current copy .
27 Beyond the Basics •When you enter a frequency into a channel, the scanner automatically turns on the delay function and DL Y appears. When de lay is turned on, the scanner automatically pauses scanning 2 seconds after the end of a transmi s- sion before scanning proceeds to the next channel.
Beyond the Basics 28 searching for and temporarily storing active frequencies If you do not have a reference to frequencies in your area, use a search (except weather service se arch) to find a transmission. Note: When the sca nner starts searching, it automatically turns on the delay function.
29 Beyond the Basics T o release the ho ld and co ntinue searching, press HOLD . Or , if you did not press HOLD , simply press FUNC and or FUNC and to continue searching .
