273-1825rc.fm Page 5 Tuesday, June 1, 1999 2:05 PM Low Input Voltage Shutdown — a special circuit shuts down the adapter when the input voltage falls below 10V DC. This safeguards batteries used to power the adapter that are susceptible to damage when operated below such voltages. Input Coil Cord — a special polyurethane material with “memory” capability enables the cord to stretch up to 5 feet and return to its original compact size of about 12 inches to prevent tangling. 5

Look for the word “OUTPUT” followed by a number and V DC. Example: OUTPUT: 18V DC. If the power adapter or computer indicates a “voltage range,” use the voltage that is closest to the mid-range. Example: OUTPUT: 10–16V DC; set the power supply to 13V DC. Note: The specific notation “V DC” might not be indicated. Instead

273-1825rc.fm Page 11 Tuesday, June 1, 1999 2:05 PM SELECTING THE ADAPTAPLUG The power adapter comes with three Adaptaplugs. The in- cluded colors and sizes are: • Blue — 5.5 · 2.1 mm • White — 5.5 · 2.5 mm • Green — 6.3 · 3 mm To select the correct Adaptaplug: 1. Disconnect the AC power adapter you are replacing from the AC outlet and from the device to be powered. 2. Refer to “Compatible Computers” on Page 21, or exam- ine the output connector of the AC adapter and compare it to the three

273-1825rc.fm Page 17 Tuesday, June 1, 1999 2:05 PM TROUBLESHOOTING Some notebook computers have power supplies in excess of the rating of this power adapter (30 watts). In most cases, this higher rating is used to both charge a completely discharged battery and power the computer at the same time. This power adapter can be used for such applications, but it is recom- mended that the computer’s battery be recharged before us- ing this adapter to operate the computer. Caution: Except as noted
