Using Ac Power - Radio Shack PRO-89 Owner's Manual

When B flashes on the display
and the scanner beeps, or if the
scanner stops operating properly,
replace the batteries.

You can power the scanner using
a 9V, 300-mA AC adapter and a
size B Adaptaplug adapter
(neither supplied). Both are
available at your local RadioShack
store.
Cautions:
•You must use a
!
Class 2 power
source that supplies
9V DC and delivers at least
300 mA. Its center tip must be
set to positive and its plug
must fit the scanner's PWR
DC 9V jack. Using an adapter
that does not meet these
specifications 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, disconnect
the adapter from AC power
before you disconnect it from
the scanner.
To power the scanner using an AC
adapter, attach the Adaptaplug to
the AC adapter so the tip reads
positive (+), then insert the
Adaptaplug into the scanner's
PWR DC 9V jack. Connect the
other end of the adapter to a
standard AC outlet.
