Important: If you encounter any problems with this kit, DO NOT RETURN TO RETAILER. Call toll-free (800) 533-2441
or e-mail us at: [email protected]. Customer Service • 150 Carpenter Ave. • Wheeling, IL 60090 U.S.A.
• Do not short circuit the battery
terminals.
• Never throw batteries in a fire or
attempt to open its outer casing.
• Use only 1.5V “AA” type, alkaline
batteries (not included).
• Insert batteries with correct polarity.
• Do not mix alkaline, standard (carbon-
zinc), or rechargeable (nickel-
cadmium) batteries.
• Non-rechargeable batteries should not
be recharged. Rechargeable batteries
should only be charged under adult
supervision, and should not be
recharged while in the product.
• Do not mix old and new batteries.
• Remove batteries when they are used
up.
• Batteries are harmful if swallowed, so
keep away from small children.
WARNING: Always check your wiring before
turning on a circuit. Never leave a circuit
unattended while the batteries are installed.
Never connect additional batteries or any
other power sources to your circuits.
WARNING:
CHOKING HAZARD - Small parts.
Not for children under 3 years.

IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads), or
μF (microfarads).
Most capacitors will have their actual value printed on them. Some capacitors may have their value printed in
the following manner. The maximum operating voltage may also be printed on the capacitor.

The letter M indicates a tolerance of +20%
The letter K indicates a tolerance of +10%
The letter J indicates a tolerance of +5%
Maximum Working Voltage
The value is 10 x 1,000 =
10,000pF or .01
μF 100V
*
Electrolytic capacitors have a positive
and a negative electrode. The negative
lead is indicated on the packaging by
a stripe with minus signs and possibly
arrowheads.
Warning:
If the capacitor
is connected
with incorrect
polarity, it may
heat up and
either leak, or
cause the
capacitor to
explode.
