Using Standard AC Power
To power the scanner from an AC out-
let, you need an AC adapter (not sup-
plied) with a 5.5 mm outer diameter/
2.1 mm inner diameter tip.
Cautions:
You must use a Class 2
power source that sup-
plies 12V DC and deliv-
ers at least 500 mA. Its center tip
must be set to positive and its
plug must fit the scanner's
DC
13.8V
jack. Using an adapter that
does not meet these specifica-
tions could damage the scanner
or the adapter.
• Always connect the AC adapter to
the scanner before you connect it
to AC power. When you finish, dis-
connect the adapter from AC pow-
er before you disconnect it from
the scanner.
1. Connect the adapter's 5.5 mm
outer diameter/2.1 mm inner
diameter tip to the adapter's cord
and set the barrel plug's tip to pos-
itive.
2. Insert the adapter's barrel plug
into the
DC 13.8V
jack on the back
of the scanner.
3. Plug the adapter into a standard
AC outlet.
CONNECTING AN
EXTENSION SPEAKER
In a noisy area, an amplified extension
speaker (available at your local Ra-
dioShack store) positioned in the right
place might provide more comfortable
listening.
Plug the speaker cable’s

-inch (3.5-

EXT SP
jack.
Note:
Connecting an external speaker
disconnects the scanner’s internal
speaker.
