We hope you enjoy your Learn to Solder Kit from
RadioShack. Please read this user’s guide before
using your new soldering kit.
•
Read instructions before operating the product.
Keep out of the reach of children.
Work only in a dry area that is free from flammable materials.
Operate the soldering iron in properly ventilated rooms or rooms
with a fume extraction system. Inhalation of soldering fumes and
particles from flux in the solder is detrimental to health.
Be careful! Hot soldering irons can cause severe burns and ignite
fires. Do not touch the tip or let it come in contact with any other
material.
Do not touch the tip of a hot soldering iron or remove solder from
its surface with your hands.
If the supplied cable is damaged, it should be repaired by the
manufacturer or its agent or a suitable qualified person in order to
avoid a hazard.
Never hold the soldering tip to the soldering point too long. This
can destroy the soldering point.
Never operate the soldering iron without the soldering tip. This
can damage the heating device.
When you are not using your soldering iron, unplug from wall
outlet.
Store the soldering iron in a dry, secure place where children
cannot reach it.
Keep the soldering iron away from dust and dirt, and clean it with
a damp cloth occasionally to keep it looking new.
This product, when used for soldering and similar applications,
produces chemicals known to the State of California to cause
cancer and birth defects (or other reproductive harm).

Preparing Your Soldering Iron
Instill good working habits. A soldering iron is not a toy.
• Prepare a clean, uncluttered workspace with no
distractions.
• Verify all tools and parts.

Green, Green, Orange = 55K
The sequence of the colored stripes
indicates the resistance value.

Speaker (1)
Caution: The solder contained in this kit contains lead.
Thoroughly wash your hands after soldering and before
consuming food.
R2 = 49K(Yellow, White, Orange)
R3 = 44K(Yellow, Yellow, Orange)
R4 = 41K(Yellow, Brown, Orange)

Copper on the printed circuit board (PCB) may oxidize
when exposed to oxygen and moisture in the air. This
oxidation can result in poorly connected welds. Before
soldering, use a scouring pad to gently clean the copper
surface so it is uniformly shiny. This will enable the solder
to properly adhere to the PCB.
R7 = 28K(Red, Gray, Orange)
1. Insert the component leads
through the correct pads on
the PCB.
Unplug the soldering iron’s power cord from the power
source and let it cool down before replacing the tip.
2. Press the iron to the pad
Leads
where the lead emerges. Heat
the pad for a few seconds,
so that the solder will flow
smoothly and evenly.
3. Do not move the iron. Instead,
touch the solder to the point
where the iron, pad, and lead
all meet.
Tin the Soldering Iron Tip
“Tinning” means coating the soldering iron tip with a small
amount of solder.
Solder
1. Plug in the iron and
wait three minutes.
2. Tin the soldering tip
by adding a small
amount of solder.
R10= 750(Violet, Green, Brown)

Soldering
Your soldering iron comes with a nickel-plated tip. When
it wears out, you can replace it with another iron tip (not
supplied).

2. Plug the soldering iron into
a wall outlet.
• Review schematics and instructions. Attention to detail
is critical.

1. Place your soldering iron on
the stand.

4. Flow a small
amount of solder
onto the joint. The
solder joint should
have enough
solder to hold
the component,
but should not extend beyond the pad and should
extend only slightly above the pad.
5. Trim the excess lead as
closely as possible to the
PCB.
Caution: Be careful when
soldering and trimming
leads. Protective eyeware is
recommended.

Assemble the Electronic Piano Kit
1 Install the Resisters (R1 to R10)
Note: Resistors are not polarized and can
be inserted facing either direction.
1. Match and install the 10 resisters
(R1 to R10) to the resistor holes
(also labeled R1 to R10) on the
PCB.
2
Install the IC Socket
Note: The integrated circuit (IC) socket MUST match the
position printed on the PCB. The dot on the NE555P IC
should be close to the first pin of the IC socket.
1. Insert the IC socket into the NE555P IC pin holes on
the PCB.
3
Install Tact Switches
1. Insert the eight tact switches into the Do,
Re, Mi, Fa, So, La, Ti, Do positions on the
PCB.
2. Solder the switches in place.
2. Solder and trim the excess leads.
4
Install the LED and
Electrolytic Capacitor
Note: The LED and electrolytic capacitor
are polarized and MUST match the position
printed on the PCB. The longer pin is
positive and the shorter pin is negative.
5
Install the Ceramic Capacitors
Note: Ceramic capacitors are not polarized and can be
inserted facing either direction.
1. Insert the two ceramic capacitors into
the C1 and C2 positions on the PCB.
2. Solder and trim the excess leads.
1. Insert the electrolytic capacitor’s
positive (longer) pin into C3 + and
the negative (shorter) pin into C3 –.
2. Bend the leads close to the
resistor.
2. Solder and trim the excess
leads.
3. Solder and trim the excess leads.
