Although printing quality is not the best, the manual was very helpful in order to reactivate this ancient but still good electronic musical instrument.
as a first-time user and buyer from this site, i found the overall service outstanding!! this product is a godsend as, without it, i would never have been able to find my way around and use my machine as intended. i will certainly use this site again as required. many many thanx!!
This manual is exactly what I needed. This site always has every manual I need, and it is also much less expensive then most other sites. This is the only manual site I will use.
Useful manual, good scan, worth the pay if you find the unit difficult to operate.
