IMPORTANT: Before you begin to assemble this kit, be sure to read the
information in the "Kit Builder's Guide."
When you perform the steps in the circuit board Pictorials, position
each part as shown. Follow the instructions carefully and read the
entire step before you perform each operation.
Capacitors will be called out by their capacitance value in pl
(picofarads) or
f-LF
(microfarads) and type.
Each circuit part in an electronic kit has its own component numbe
(R2,C4,etc.). Use these numbers when you want to identify the saffil
part in the various sections ofthe Manual. These numbers, which arl
especially useful if a part has to be replaced, appear:
Due to the small foil area around some ofthe circuit board holes and
the small area between the foils, use the utmost care to prevent solder
bridges between adjacent foils. Use only a minimum amount of
solder and small tip soldering iron of not over 40 watts. Allow the
iron to reach operating temperature; then apply it only long enough
to make a good solder connection. If you think a solder bridge may
exist, but you are not sure, compare the foil on the circuit board with
the "Circuit Board X-Ray View" in the "Illustration Booklet."
Most kits use a separate "Illustration Booklet" that contains illustration
(Pictorials, Details, etc.) that are too large for the Assembly Manual. Kee
the "Illustration Booklet" with the Assembly Manual. The illustrations in
i
are arranged in Pictorial number sequence.
SAFETY WARNING: Avoid eye injury when you clip off excess lea
lengths. Hold the leads so they cannot fly toward your eyes.

To eliminate a solder bridge; hold the circuit board above the solder-
ing iron and reheat the solder. As the solder melts; it will flow down
the iron.
If your work surface is smooth, place the circuit board on a cloth to
prevent it from sliding around when you solder component leads to
the foil.
Resistors will be called out by their resistance value inn (ohms) or in
ill
(1000 ohms).
