Installing batteries

• Remove the safety cover from the battery holder (if your holder has one) with a Phillips head screwdriver.
• Insert three (3) 1.5V AA batteries (not included) in the holder.
• Be sure to orient the battery “+” as marked in the holder.
• Replace the cover (if your holder had one). When installing a battery, be sure the spring is compressed straight back, and not bent up, down, or to one side.
• Battery installation should be supervised by an adult.

FM Radio

• Assemble the circuit as shown.
• Spread the red (antenna) wire from the FM module across the table.
• Turn on the slide switch (S1) and press the R button on the FM module (FM).
• Now press the T button several times to scan for radio stations.
• Adjust the volume using the lever on the adjustable resistor (RV).

Amplifier

• Modify the Project 1 circuit by removing the 2-snap wire and the single snap that was connected to the FM module (FM) in assembly step 2.
• Note that the single snap is beneath the adjustable resistor (RV).
• Position the adjustable resistor (RV) position lever away from the speaker and turn on the slide switch (S1). You should be able to touch point A with your finger and hear static.
• Listen closely to the speaker (SP) or wet your finger if you don’t hear any sound.
• High-frequency clicks, static or even an AM radio station should be coming from the speaker indicating that the amplifier is powered on and ready to amplify signals.
• The circuit may make a sound on its own. Do not worry, this is normal with high-gain amplifiers.

Electronic Kazoo

• Use the circuit from Project 2. Place one finger on point A and a finger from your other hand on point B. You should hear sound. You may be able to change the pitch of the sound by pressing harder on the snaps.
• If you practice and learn the amount of pressure required to make each note, you may even be able to play a few songs. Your fingers provide a feedback path across the amplifier (U4), making fun sounds.

Trombone Sounds

• Use the circuit from Project 2. Place one finger on point C and a finger from your other hand on point B. The trombone should start playing.
• To change the pitch of the sound, slide the RV control slider back and forth.
• By moving the slider, you will be able to play a song much like a trombone player makes music. The circuit may be silent at some positions of RV.

FM radio is Frequency Modulation radio.
A radio station’s transmit frequency is varied (or modulated) a little to encode voice or music on it. An FM transmitter is placed high on a building or tower to send out an FM radio wave through the air.

The invisible radio wave is captured by an antenna that is connected to a radio receiver (like the red antenna wire included in your Snap Circuits® FM Radio). In your FM module (FM) the radio wave from the antenna is decoded and converted to an electrical signal. Then the power amplifier IC (U4) boosts the electrical signal so you can hear the music through your speaker.

WARNING: SHOCK HAZARD – Never connect Snap Circuits® to the electrical outlets in your home in any way!
WARNING: CHOKING HAZARD- Small! parts. Not for children under 3 years.

Adult Supervision

Because children’s abilities vary so much, even with age groups, adults should exercise discretion as to which experiments are suitable and safe (the instructions should enable supervising adults to establish the experiment’s suitability for the child). Make sure your child reads and follows all of the relevant instructions and safety procedures, and keeps them at hand for reference. This product is intended for use by adults and children who have attained sufficient maturity to read and follow directions and warnings.

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.
• This instruction manual must be retained since it contains important information.

Batteries: X3

• Use only 1.5V AA type, alkaline batteries (not included).
• Insert batteries with the correct polarity.
• Do not mix old and new batteries.
• Remove batteries when they are used up.
• Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium batteries.
• Do not connect batteries or battery holders in parallel.
• Do not short-circuit the battery terminals.
• Never throw batteries in a fire or attempt to open its outer casing.
• Batteries are harmful if swallowed, so keep away from small children.
• Non-rechargeable batteries should not be recharged.
