Preparation
Its center tip must be set to negative and
its plug must fit the keyboard's
DC 12V
jack. Using an adapter that does not
meet these specifications could damage
the keyboard or the adapter.
Always connect the AC adapter to the
keyboard before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you dis-
connect it from the keyboard.
1. Insert the Adaptaplug adapter into the
adapter’s cord so it reads
– TIP
.
2. Connect the AC adapter’s barrel plug to
the
DC 12V
jack on the back of the key-
board.
3. Plug the AC adapter’s other end into a
standard AC outlet.
REPLACING THE MEMORY
BATTERY
Your keyboard uses one lithium battery to
protect some types of data when it is turned
off. This battery is installed at the factory,
and lasts up to 5 years. If the keyboard’s
memory is erased when you turn the key-
board off, take the keyboard to your local Ra-
dioShack store to replace the lithium battery.
RESETTING THE
KEYBOARD
Note:
Resetting the keyboard clears all infor-
mation you stored in the keyboard’s memory,
including the parameter settings, song se-
quencer, pattern sequencer, and registration
memory. Resetting the keyboard’s parame-
ter settings clears only those settings from
the keyboard’s memory.
To reset the keyboard, turn the power off.

CONNECTING
HEADPHONES
To listen to your keyboard without disturbing
others, you can connect an optional pair of
stereo headphones with a
1
/
4
-inch (6.35-mm)
plug. Your local RadioShack store sells a
wide selection of headphones. Insert the
headphones’ plug into the
PHONES/OUTPUT
jack on the left side of the keyboard.
Note
: Connecting headphones disconnects
the keyboard’s built-in speakers.
Listening Safely
To protect your hearing, follow these guide-
lines when you use headphones.
Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to a
comfortable level.
Do not listen at extremely high volume
levels. Extended high-volume listening
can lead to permanent hearing loss.
Once you set the volume, do not
increase it. Over time, your ears adapt
to the volume level, so a volume level
that does not cause discomfort might
still damage your hearing.
CONNECTING AN
EXTERNAL AMPLIFIER
To amplify your keyboard’s sound, you can
connect it to an optional external amplifier
using an audio cable with a
1
/
4
-inch (6.35-
mm) plug (not supplied). To connect an ex-
ternal amplifier to your keyboard, insert the
cable’s plug into the
PHONES/OUTPUT
jack
on the left side of the keyboard, and connect
