- How to assemble Keyboard Unit
1. Assemble them in order from "1" to "8". (See the figure below.)
2. After that, bend the crows (7 in total) until they get the right angles with the marks printed on "8".
Note) If "5" is not set collectly, defective contact may occur on "6".
To avoid this problem, hold "5" using "7" just before putting "8".
