He bought the Yamaha Genos we dont know how to find the serial namber
can you help us ?

On page 1 of the Owners manual it tells you where to look!

On the name plate on the back of the keyboard lower Left hand side. One third of the way from the left side.
Just below the picture of it, in the manual, it has three lines for you to fill in to remember the numbers for your keyboard.

Quote manual:
"The model number, serial number, power requirements, etc., may
be found on or near the name plate, which is at the bottom of the unit."

(At my Genos the label is at the front part of the bottom, aprox at the middle of the lenght, a bit at right side)

The serial number is also to fid at the original box Genos is shipped in.

thank you all
