This equipment has been tested and found
to comply with the limits for a Class B digital
device, pursuant to Part 15 of the
FCC
Rules
. These limits are designed to provide
reasonable protection against harmful
interference in a residential installation. This
equipment generates, uses and can radiate
radio frequency energy and, if not installed
and used in accordance with the
instructions, may cause harmful interference
to radio communications.
However, there is no guarantee that
interference will not occur in a particular
installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference
by one or more of the following measures:
Reorient or relocate the receiving
antenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
Consult your local RadioShack store or
an experienced radio/TV technician for
help.
If you cannot eliminate the interference,
the FCC requires that you stop using
your keyboard.
Changes or modifications not expressly
approved by RadioShack may cause
interference and void the user’s authority to
operate the equipment.
You must use shielded interface cables with
this equipment.

You can power your keyboard using internal
batteries or with standard AC power using
an optional AC adapter.
The keyboard retains the following settings
in its memory even when the power is turned
off as long as power is supplied to it (either
by the batteries or AC adapter):
tone number
layer and split
split point
touch response
reverb/chorus
•DSP
equalizer
rhythm number
tempo
•mixer mode
MIDI keyboard channel
MIDI in chord judge
MIDI accompaniment out
assignable jack
accompaniment volume
user area tone (synthesizer tone)
user area accompaniment
user area DSP
song memory
registration mode
If the keyboard loses power (by
disconnecting the AC adapter when
batteries are not installed or the batteries
lose power), these settings are lost or
initialized to factory settings.
You can also delete or initialize some
settings independently. See “Resetting the
Keyboard” on Page 15.

Your keyboard can use 6 D batteries (not
supplied) for power. For the best per-
formance and longest life, we recommend
RadioShack alkaline batteries.
1. While pressing the tabs on the battery
compartment cover on the bottom of the
keyboard, pull up the cover to remove it.
2. Place the batteries in the compartment
as indicated by the polarity symbols (+
and –) marked next to the compartment.
3. Replace the cover.
When the keyboard stops operating
properly, replace the batteries.

You can power the keyboard using a 9V,
800 mA AC adapter and a size M
Adaptaplug™ adapter (neither supplied).
Both are available at your local RadioShack
store. Connecting an AC adapter
automatically disconnects any internal
batteries.
1. Set the AC adapter’s voltage switch to
9V
.
2. Insert the Adaptaplug adapter into the
adapter’s cord so it reads – TIP.
3. Connect the AC adapter’s barrel plug to
DC 9V
on the back of the keyboard.
4. Plug the AC adapter’s other end into a
standard AC outlet.

Installing Batteries
Use only fresh batteries of the required size
and recommended type.
Do not mix old and new batteries, different
types of batteries (standard, alkaline, or
rechargeable), or rechargeable batteries of
different capacities.
If you do not plan to use the keyboard with
batteries for a week or more, remove the
batteries. Batteries can leak chemicals that
can destroy electronic parts.
Using AC Power
You must use a Class 2 power
source that supplies 9V DC 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 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
disconnect it from the keyboard.
