Using AC Power
To operate the scanner from AC power, you need an AC adapter
such as Radio Shack Cat. No. 273-1665.
Cautions:
• To prevent electric shock, the plug’s blades are polarized
and fit only one way. If the plug does not fit easily, turn it over
and try again. Do not force the plug into the AC outlet.
• You must use an AC adapter that supplies 9 volts and deliv-
ers at least 300 milliamps. Its center tip must be set to nega-
tive, and its plug must correctly fit the scanner’s
PWR
and
CHG
jacks. The recommended adapter meets these specifi-
cations. Using an adapter that does not meet these specifi-
cations could seriously damage the scanner or the adapter.
• Always plug the AC adapter’s barrel plug into the scanner
before you plug the adapter’s power module into the AC out-
let. Always unplug the adapter’s power module from the AC
outlet before you unplug the adapter’s barrel plug from the
scanner.
Plug the adapter’s barrel plug into the scanner’s
PWR
jack. Then
plug the adapter’s power module into a standard AC outlet.
