powering your scanner You can power your scanner from any of three sources: • internal batteries (not supplied) • standard AC power (using an optional AC adapter) • vehicle battery power (using an optional DC adapter) Before installing batteries, set the switch in the battery compartment to match the type of batteries you will use. Select ALKALINE for non-rechargeable battery types and RECHARGEABLE for rechargeable battery types, including Ni-Cd and Ni-MH.
Y Install 2 AA batteries, matching the polarity symbols (+ -). Z Replace the cover.
Warning: Set ALKALINE/RECHARGEABLE to RECHARGEABLE for use only with nickel cadmium (Ni-Cd) or nickel metal hydride (Ni-MH) rechargeable batteries. Never attempt to recharge nonrechargeable batteries. Non-rechargeable batteries can get hot or explode if you try to recharge them. Cautions: • Use only fresh batteries of the required size and recommended type. • Always remove old or weak batteries. Batteries can leak chemicals that destroy electronic circuits.
The scanner has a built-in circuit that lets you recharge Ni-Cd or Ni-MH batteries while they are in the scanner. To charge the batteries, set ALKALINE/ RECHARGEABLE inside the battery compartment to RECHARGEABLE, install the batteries in the scanner, and connect an external AC or DC adapter to the scanner's DC 6V jack (see “Using AC Power” on Page 10 or “Using Vehicle Battery Power” on Page 11). CHArg appears while the scanner is charging the batteries.
until it beeps every 15 seconds and flashes. • To prevent damage to Ni-Cd and Ni-MH batteries, never charge them in an area where the temperature is above 113°F (40°C) or below 40°F (4°C). • If you connect an external power source to the scanner with ALKALINE/RECHARGEABLE set to ALKALINE, CHArg appears but the scanner does NOT charge the batteries. This is because the scanner's microprocessor unit does not recognize the switch position when you incorrectly connect an external power source.
and recycle these batteries at the end of their useful life, when taken out of service in the United States or Canada. The RBRC program provides a convenient alternative to placing used rechargeable batteries into the trash or the municipal waste stream, which may be illegal in your area. Please call 1-800-THE-SHACK (1-800-843-7422) for information on rechargeable battery recycling and disposal bans/restrictions in your area.
Follow these steps to use the scanner on AC power. X Make sure the power is turned off. Y Insert the Adaptaplug into the AC adapter's cord so it reads TIP +. Then, insert the Adaptaplug into the scanner's DC 6V jack. Z Plug the AC adapter into a standard AC outlet. Using Vehicle Battery Power You 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).
X Make sure the power is turned off. Y If the adapter has a voltage switch, set the switch to 6V. Z Insert the Adaptaplug into the DC adapter's cord so it reads TIP +. Then, insert the Adaptaplug into the scanner's DC 6V jack. [ Plug the other end of the adapter into your vehicle's cigarette-lighter socket. If rechargeable batteries are installed and ALKALINE/RECHARGEABLE is set to RECHARGEABLE, the adapter powers the scanner and recharges the installed batteries at the same time.
setting up your scanner Connecting the Antenna To attach the supplied flexible antenna to the connector on the top of your scanner, align the slots around the antenna's connector with the tabs on the scanner's BNC connector. Then slide the antenna's connector down over the scanner's connector and rotate the antenna connector's outer ring clockwise until it locks into place.
Note: Always use 50-ohm, RG-58, or RG-8, coaxial cable to connect an outdoor antenna. If the antenna is over 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 variety of BNC adapters. Connecting an Earphone/Headphone For private listening, you can plug a 1/8-inch (3.5 mm) mini-plug earphone or mono headphones (not supplied) into the headphone jack on top of your scanner.
• Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort 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. Doing so can create a traffic hazard and could be illegal in some areas. If you use an earphone or headphones with your scanner, be very careful. Do not listen to a continuous broadcast.
Attaching the Belt Clip To make your scanner easier to carry when you are on the go, use the supplied belt clip. Use a Phillips screwdriver and the supplied screws to attach the clip to the scanner.
About Your Scanner We use a few simple terms in this manual to explain the features of the scanner. Familiarize yourself with these terms and the scanner's features, and you can put the scanner to work for you right away. Simply determine the type of communications you want to receive, then set the scanner to scan those communications. A frequency, expressed in kHz or MHz, is the tuning location of a station. To find active frequencies, you use the search function or refer to a frequency reference.

WX, POL FIRE, AIR, MRN, or HAM - appears along with an indicator that shows the current service bank during a service search. ALT - appears during a WX alert or while the signal stalker function is on.
Understanding Banks Service Banks The scanner is preprogrammed with all the frequencies allocated to the weather, ham, marine, aircraft, and police (fire/emergency) services. Channel Storage Banks To make it easier to identify and select the channels you want to listen to, the 200 channels are divided into 10 channel-storage banks. Each bank has 20 channels. Use each channel-storage bank to group frequencies, such as those for the police department, fire department, ambulance services, or aircraft.
operating your scanner Turning On The Scanner and Setting Squelch Your scanner is preprogrammed at the factory with 150 of the most frequently used frequencies in Channels 1 to 150. You can scan these frequencies as soon as you turn on the scanner. Note: Make sure the scanner's antenna is connected before you turn it on. X Turn SQUELCH fully counterclockwise. Y Press and hold for about 2 seconds to turn the scanner on, then turn VOLUME clockwise until you hear a hissing sound.
Excellent references for active frequencies are the RadioShack Police Call Guide including Fire and Emergency Services, and Official Aeronautical Frequency Directory. We update these directories every year, so be sure to get a current copy. Follow these steps to store frequencies into channels. X Press HOLD. Then enter the channel number where you want to store a frequency, then press FUNC + PGM. The channel number appears. Y Use the number keys and .
•When you enter a frequency into a channel, the scanner automatically turns on the delay function and DLY appears. When delay is turned on, the scanner automatically pauses scanning 2 seconds after the end of a transmission before scanning proceeds to the next channel. To turn the function off or on, press FUNC + DLY. •If you enter a frequency that has already been entered elsewhere, the scanner sounds an error tone and displays the channel that was duplicated.
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 search) to find a transmission. Note: When the scanner starts searching, it automatically turns on the delay function. To turn delay on or off, press FUNC + DLY. Service Search You can search for weather, ham, marine, aircraft, or police (fire/emergency) transmissions without knowing the specific frequencies used in your area.
To release the hold and continue searching, press HOLD. Or, if you did not press HOLD, simply press FUNC + or FUNC + to continue searching. Note: Because there are many different frequencies allocated to fire and police departments, it can take several minutes to search all the service frequencies. Storing Frequencies into Channels During Service Search You can store frequencies you found during service search or service search hold mode into channels.
Scanning the Stored Channels To begin scanning channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. (See “Locking Out Channels” on Page 48 and “Turning Channel-Storage Banks On and Off” on Page 48). When the scanner finds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning. Notes: • If you have not stored frequencies into any channels, the scanner does not scan.
To manually select a channel, press HOLD, enter the channel number then press HOLD again. Or, during scanning, if the radio stops at a channel you want to listen to, press HOLD once. (Repeatedly pressing HOLD at this time causes the scanner to step through the channels.) Press SCAN to resume automatic scanning. Signal Stalker Your scanner's Signal Stalker feature lets you set the scanner so it detects then displays the frequency of a nearby strong radio transmission.
Signal Stalker might not find the transmission you are searching for, or it might find a transmission other than the one you are searching for. You can screen unwanted transmissions by pressing FUNC + L/O to lock them out. See “Locking Out Frequencies” on Page 49 for more information. • Signal Stalker cannot detect satellite dishes or any transmitter with a frequency above or below the frequency ranges listed under “Setting the Signal Stalker Options” on Page 32.
