PRO-24 (200-0503) Power Sources Faxback Doc. # 3951 You can power your scanner from any of these power sources: Internal batteries Standard AC power (using an optional AC adapter) Vehicle battery (using an optional DC adapter) Using Internal Batteries You can power your scanner with four AA batteries. For the longest life and best performance, we recommend alkaline batteries such as Cat. No. 23-552. Or, you can use rechargeable nickel-cadmium batteries (Cat. No. 23-125). Follow these steps to install or replace batteries. 1. If the scanner is on, turn VOLUME/OFF fully counterclockwise until it clicks to turn it off. 2. Press down the tab on the battery compartment cover and lift open the compartment. 3. Remove any old batteries from the compartment and cover. Caution: Always dispose of old non-rechargeable batteries promptly and properly. Do not bury or burn them. 4. Install two batteries in the compartment and two in the cover as indicated by the polarity symbols (+ and -) marked inside the compartment and cover. 5. Replace the cover. If L appears on the display or your scanner beeps every 15 seconds, immediately replace or recharge all four batteries. See "Important Information About the External Power Jacks" and "Charging Nickel-Cadmium Batteries." Important Information About the External Power Jacks The scanner has two external power jacks - POWER and CHARGE. It is important that you understand the purpose of each jack before you connect any adapter to the scanner. The POWER jack powers the scanner and disconnects the internal batteries. You can use this jack with either an AC or DC adapter, regardless of the type of batteries you installed. The CHARGE jack powers the scanner and also charges the internal batteries. Use the CHARGE jack only when rechargeable nickel-cadmium batteries are installed. Warning: Never use the CHARGE jack with non-rechargeable batteries, they become very hot and could explode. Using AC Power To operate the scanner from AC power, you need an AC adapter such as Cat. No. 273-1652. Cautions: You must use an AC adapter that supplies 12 volts and delivers at least 200 milliamps. Its center tip must be set to positive, and its plug must correctly fit the scanner's POWER jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications can damage your scanner and the adapter. Always plug the adapter into the scanner before you plug it into the AC outlet. Always unplug the adapter from the AC outlet before you unplug it from the scanner. Follow these steps to connect an AC adapter to the scanner. 1. Connect the adapter's green barrel plug to the adapter's cord and set the barrel plug's tip to positive. 2. Plug the adapter's barrel plug into your scanner's POWER jack. Note: If you have installed rechargeable nickel-cadmium batteries in the scanner, you can connect the AC adapter to the CHARGE jack. This powers the scanner and recharges the batteries at the same time. See "Charging Nickel-Cadmium Batteries." 3. Plug the adapter's power module into a standard AC outlet. Using Vehicle Battery Power You can power the scanner from your vehicle's battery power, using a DC adapter (Cat. No. 270-1533). Cautions: You must use a DC adapter that supplies 12-volts and delivers at least 200 milliamps. Its center tip must be set to positive, and its plug must correctly fit the Scanner's POWER jack. The recommended adapter meets these specifications. Using an adapter that does not meet these specifications can damage your scanner and the adapter. Your vehicle must have a 12-volt negative-ground electrical system. To protect your vehicle's electrical system, always plug the adapter into the scanner before you plug it into your vehicle's cigarette socket. Always unplug the adapter from the vehicle's cigarette-lighter socket before you unplug it from the scanner. Follow these steps to connect a DC adapter to the scanner. 1. Plug the adapter's barrel plug into your scanner's POWER jack. Note: If you have installed rechargeable batteries, you can connect the DC adapter to the CHARGE jack. This powers the scanner and recharges the batteries at the same time. 2. Insert the other end of the adapter into your vehicle's cigarette lighter socket. Note: If the scanner does not operate properly when you use a DC adapter, unplug the adapter from the lighter socket and clean the socket to remove ashes and other debris. Charging Nickel-Cadmium Batteries This scanner has a built-in charging circuit that lets you recharge nickel-cadmium batteries while they are in the scanner. To charge the batteries, simply connect an AC or DC adapter (Cat. No. 273-1652 or 270-1533) to the scanner's CHARGE jack. Warning: Do not connect either adapter to the scanner's CHARGE jack if you installed non-rechargeable batteries (standard, extra-life, or alkaline). Non-rechargeable batteries become hot and can even explode if you try to recharge them. It takes 10 to 18 hours to recharge batteries that are fully discharged. You can operate your scanner while recharging nickel-cadmium batteries, but it takes longer to fully charge the batteries. Cautions: Do not overcharge nickel-cadmium batteries. To prevent damaging nickel-cadmium batteries, never charge them in an area where the temperature is above 90 degrees F or below 40 degrees F. Important: Your scanner is capable of using rechargeable nickel cadmium batteries. At the end of the batteries' useful life, they must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curb-side collection, drop-off boxes at retailers, recycling collection centers, and mail-back programs. (br/all-01/10/95)
