First, carry out the steps for inserting
the circuit board into the main unit in
the order of (1) to (6) and then the
last steps in the order of (7) to (9) to
complete.
Attach the cord to the circuit board
Affix the white cord to the circuit board with
cellophane tape so that it is out of the way
when inserting the circuit board into the
main unit.
Attach the speaker
Attach the speaker to the hole on the main
unit, and secure with washer head screws.
Be careful not to let any parts of the cords
on the speaker get caught in the screws.
Connect the battery connector
Insert the connector for the battery box
into the plug on the circuit board.
Screw the circuit board onto the main unit
Being careful not to let the cords get caught in any parts,
affix the circuit board to the main body with screws.
1. Pass the
electrode cord
through the hole
on the main unit.
Attach the electrode
2. Form a knot in the
cord at about 4 to 5
cm from the contact
ring, and firmly affix
the contact ring to
the circuit board with
a flange screw.
1. Pass the contact rings of the blue and white cords through the holes on the
left and right of the slider panel and turn them in toward the inside.
Install the slider panel
2. Firmly attach the contact rings to the slider panel using
washer head screws.
Lightly place each knob onto a control dial, and
turn each one all the way to the left. Next, remove
each knob, and then place each back onto a
control dial using the grooves on the knob and the
grooves on the control dials as a guide and push
each knob onto its control dial all the way. If they
are lined up correctly, you will be able to turn the
knobs within the range shown in the picture on
the bottom left.
Insert the batteries
Insert the batteries into the battery box on the main unit.
Attach the knobs
Attach the labels included in the magazine to the knobs, and then fit each
knob onto a control dial.
* Be sure to use new AA alkaline batteries.
Insert the batteries in the correct way.
Attach the back cover
Cut the back cover out and remove it from the cardboard case, and then
secure it with washer head screws onto the back of the main unit as
shown in the picture.
Set the switches and
knobs as shown below
Touch the slider panel with the tip of the electrode
to produce a sound from the speaker
Sliding the tip to
the left will
produce a lower
pitch sound and to
the right, a higher
pitch sound. By
sliding the tip
across the panel
from one end to
the other, you can
produce notes in
four octaves.
No sound is produced.
● Ensure that you are using new batteries.
Be sure to always use new alkaline batteries to replace any that have run out of power.
● Check all connections.
Check to ensure that the connector for the battery box is fully engaged with the plug on the
circuit board. Securely reconnect the connector if it is loose.
● Check the contact ring and screw on each side of the slider panel.
No sound will be produced if either contact ring is not making good contact with the slider
panel. No sound will be produced if it appears that each contact ring is just touching the slider
panel, so reattach the contact rings so that they are as flat against the surface of the slider
panel as possible.
Pitch increases towards the left of the slider panel and decreases towards
the right.
● Check the colors of the cords connected to the slider panel.
If the blue and while cords are connected in reverse, the relationship between pitch and
position on the slider panel will be inverted.
The pitch of the sound does not change even if the electrode is moved
along the slider panel.
● Check the contact ring and screw on the left side of the slider panel.
The pitch will not change if the contact ring on the left is not making good contact with the
slider panel. Electricity will not conduct if it appears that the contact ring is just touching the
slider panel, so reattach the contact ring so that it is as flat against the surface of the slider panel
as possible.

side should be
on the outside.
* Push down on the screw to
securely attach the cover.

Capacitor C15 may be tipped over, but this is
not a problem.
* The unit may not make any
sound unless the contact
rings and slider panel are
in firm surface contact
with each other.
