Important! insert the LED in the correct
way, see length of the wires.
Polarity of the elco is important otherwise
you can damage the circuit or it will not
have a correct function.

5. Endmontage des Pianos (bei AW-860K is alles bereits vorgelötet !)
5. Final assembly of the Piano
For the wiring of the speaker you need a red and black
wire. When necessary you have to prepare them in the
following way.
1) Remove about 5mm of the
plastic wire insullation
2) Twist the copper wires
3) Presolder the copper
wire. If this step is done,
it will be more easy to
solder the wire in a later
step.
