14-1225.fm Page 6 Friday, July 2, 1999 9:00 AM POWERING THE SCP-84 You can power your SCP-84 from any of three power sources: • Internal batteries (not supplied) • Standard AC power (with an optional AC adapter) • Your vehicle’s cigarette-lighter socket (with an optional DC adapter) Note: Connecting an optional adapter disconnects internal batteries. Using Batteries You can power your SCP-84 from two AA batteries. We recommend alkaline batteries, such as RadioShack Cat. No. 23-557, not supplied.
14-1225.fm Page 7 Friday, July 2, 1999 9:00 AM Cautions: • Do not mix old and new batteries, different types of batteries (standard, alkaline, and nickel-cadmium), or rechargeable batteries of different capacities in the SCP-84. • Use only fresh batteries of the required size and type.

14-1225.fm Page 8 Friday, July 2, 1999 9:00 AM Cautions: • Never leave dead or weak batteries in the SCP-84. • If you do not plan to use the SCP-84 for a month or more, or if you plan to use only AC or vehicle battery power, remove the batteries. • Dispose of batteries promptly and properly; do not bury or burn them. Note: If your SCP-84 locks up, simply remove one of the batteries then reinstall it. Important: Your SCP-84 is capable of using rechargeable nickel-cadmium batteries.
14-1225.fm Page 9 Friday, July 2, 1999 9:00 AM Cautions: • The recommended AC adapter supplies 3 volts and delivers at least 300 milliamps. Its center tip is set to negative, and its plug correctly fits the DC 3V jack on the bottom of the SCP-84. Using an adapter that does not meet these specifications could damage the SCP-84 or the adapter.
14-1225.fm Page 10 Friday, July 2, 1999 9:00 AM 3. Insert the barrel plug into the SCP-84’s DC 3V jack. 4. Plug the AC adapter into a standard AC outlet. Using Your Vehicle’s Cigarette-Lighter Socket To power the SCP-84 from your vehicle’s cigarette-lighter socket, you need a DC adapter, such as Cat. No. 2701560. Cautions: • The recommended DC cigarette-lighter adapter supplies 3 volts and delivers at least 300 milliamps.
14-1225.fm Page 11 Friday, July 2, 1999 9:00 AM • Always plug the DC adapter’s barrel plug into the SCP-84 before you plug its power module into your vehicle’s cigarette-lighter socket, and unplug its power module from your vehicle’s cigarette-lighter’s socket before you unplug its barrel plug from the SCP-84. Follow these steps to power the SCP-84 from your vehicles’s cigarette-lighter socket. (illus) 1. Set the adapter’s voltage switch to 3V. 2. Insert the 3.4 mm outer diameter/1.
