PRO-46 (200-0305) Preparation Faxback Doc. # 3599 POWER SOURCES You can power your scanner from any of three sources: Internal battery power Standard AC power (using an optional AC adapter) Vehicle battery power (using an optional DC adapter) USING BATTERIES You can operate your scanner from four AA batteries. For longest operation and best performance, we recommend alkaline batteries (Radio Shack Cat. No. 23-552). Or, you can use rechargeable nickel-cadmium batteries (Cat. No. 23-125). WARNING: The scanner has a built-in circuit that lets you recharge nickel-cadmium batteries inside the battery compartment. However, you must never use this circuit when you have installed non-rechargeable batteries in the scanner. To install batteries in your scanner, follow these steps. 1. Press down on the arrow and slide the cover in the direction of the arrow to remove the battery compartment cover. 2. Pull the ribbon to remove the battery holder from the compartment and remove any old batteries. 3. Install four AA batteries, as indicated by the polarity symbols (+ and -) marked on the battery holder. 4. Place the battery holder in the compartment so the holder's metal contacts line up with the metal contacts in the battery compartment. 5. Replace the battery compartment cover. You scanner beeps every 15 to 30 seconds when the batteries are low. When this happens, immediately replace or recharge all four. CONNECTING THE ANTENNA Follow these steps to attach the supplied flexible antenna to the connector on the top of your scanner. 1. Slip the slot in the antenna's connector over the protrusion on the jack. 2. Press down and rotate the antenna's base until it locks into place. Connecting an Optional Antenna The antenna connector on your scanner makes it easy to use your scanner with a variety of antennas. You can remove the supplied antenna, if you want, and attach a different one, such as an external mobile antenna or outdoor base antenna. Your local Radio Shack store sells a variety of antennas. Use coaxial cable to connect an outdoor antenna. Always use 50-ohm coaxial cable, such as RG-58 or RG-8. For lengths over 50 feet, use RG8 low-loss dielectric coaxial cable. You will also need a BNC connector to connect an optional antenna (Cat. No. 278-103 or 278-185). WARNING: When installing or removing an outdoor antenna, use extreme caution. If the antenna starts to fall, let it go! It could contact overhead power lines. If the antenna touches the 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. CONNECTING AN EARPHONE/HEADPHONES For private listening, plug an earphone or headphones into the EARPHONE jack on top of your scanner. This automatically disconnects the internal speaker. We recommend Radio Shack's earphone (Cat. No. 33-175) or mono headphones (Cat. No. 20-210). Hearing Comfort and Your Health To protect your hearing, follow these guidelines when you use an earphone/headphones: Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss. Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level. 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 wear headphones or an earphone while you drive a vehicle or ride a bicycle. This can create a traffic hazard and is illegal, in some areas. Even though some headphones and earphones are designed to let you hear some outside sounds when you listen at normal levels, they still present a traffic hazard. CONNECTING AN EXTENSION SPEAKER In a noisy area, an extension speaker, such as Radio Shack's Cat. No. 21- 539, positioned in the right place, might provide more comfortable listening. Plug the speaker cable's 1/8-inch mini-plug into your scanner's EARPHONE jack. RESETTING THE SCANNER If the scanner's display locks up or does not work properly after you connect a power source, you might have to reset the scanner. CAUTION: This procedure clears all the information you have programmed into the scanner. Use this procedure only when you are sure your scanner is not working properly. 1. Turn off the scanner. 2. While you press and hold down the 2 and 9 keys, turn on the scanner. USING THE BELT CLIP You can use the supplied belt clip to make the scanner easier to use when you are on the go. Use the two supplied screws to attach the belt clip to the scanner. Then slide the belt clip over your belt or waistband. (ALL-12/13/94)
