NOTICE: you can stop all playing actions directly with the STOP button!
c. Switch on the ON/OFF switch (you will hear a starting tune) Often the sound is too
loud at the start, turn down the piano with „volume -“ until the volume and quality of
the sound is OK.
CAUTION... if there is any smoke or a component getting very hot, switch o
the piano immediately and check all part directions and polarity!
When there is no smoke you had a good start and we can continue testing

check batteries rst and then all part assembly (Sound IC, opamp, battery- and

Push again for more melodies.
f. During a DEMO melody you can check the VOLUME + and VOLUME - buttons to
