User manual / Basic, entry-level (cheap), "Teaching", 61 key YM-638 Keyboard

[Duane Lewis]

Hi folks ... I'm a veteran piano and keyboard guy and have used a Roland FP3 professionally for about 20 years. Recently decided to buy a used, lightweight YM-638 for teaching my 6 year old grandson and getting him interested. Seller did not have any documentation. It seems to work fine (for a virtual toy) but a manual would be helpful in figuring out the buttons, functions, sequence of operations to trigger/use in teaching process.

I've scrambled around the web and had no luck. Can anyone help locate a manual or maybe a .pdf of same?

Thanks in advance from London Onario Canada.
