Casio S360 question/ L/R pan

[Bud]

I’m trying to figure out on my CasioS360 whether I can have different outputs ( to a mixer) in split mode, Using a stereo output cable . I want to sent to 2 channels to control separate volumes. Function 6 gets into Dual mode, with a Pan function turned on, But I cannot find a way to adjust the L/R pan. Am I missing something ? The
Manual , EN -20 is vague. And page EN-46 does not indicate how to do the pan, Left/right ,’
Any ideas? Thx for any answer .
