Depreciation on BA II

Hi I read somewhere that its possible to do all the depreciation expense calculations (4 diff methods) on the BA II as its programmed for it. Would any one be nice enough to share how to get to that function? I bought my calc a while back and have lost the manual! Thanks loads
