Using AC Power
You can power your keyboard from
standard AC power using an optional 9-
volt AC adapter (such as RadioShack
Cat. No. 273-1656).
Cautions
:
You must use an AC adapter that
supplies 9 volts and delivers at least
800 mA. Its center tip must be set to
negative and its plug must fit the
keyboard’s
DC 9V
jack. The recom-
mended adapter meets these speci-
fications. Using an adapter that
does not meet these specifications
could damage the keyboard or the
adapter.
Always plug the AC adapter into the
keyboard before you plug it into the
AC outlet. Always unplug the AC
adapter from the AC outlet before
you unplug it from the keyboard.
•Be sure
POWER/MODE
is set to
OFF
before you connect or disconnect
the adapter.
Follow these steps to connect an AC
adapter to the keyboard.
1. Connect the AC adapter’s 5.5 mm
outer diameter/2.1 mm inner diame-
ter barrel plug to the
DC 9V
jack on
the back of the keyboard.
2. Plug the AC adapter’s other end into
a standard AC outlet.
Using Vehicle Battery Power
You can power your keyboard from your
vehicle’s cigarette-lighter socket using
an optional 9-volt DC adapter (such as
RadioShack Cat. No. 273-1815).
Cautions:
You must use a DC adapter that
supplies 9 volts and delivers at least
800 mA. Its center tip must be set to
negative and its plug must fit the
keyboard’s
DC
9V
jack. Using an
adapter that does not meet these
specifications could damage the
keyboard or the adapter.
Always plug the DC adapter into
the keyboard before you plug it into
the cigarette-lighter socket. Always
unplug the DC adapter from the
cigarette-lighter socket before you
unplug it from the keyboard.
•Be sure
POWER/MODE
is set to

before you connect or disconnect
the adapter.
