Switch off sleep-modus

[Bassjens]

My sister has got an old Casio CT-650 but no manual. The Keybord switches off automatically when not played for 1 or 2 minutes.How can we switch off the sleeping modus?

Thanks for your help and have an nice day.

I just googled this, and it looks like the whole world is looking for the elusive manual for the CT-650 (in order to get over this issue you are having).....
