In G-70 thay are called "User Programs".
You can access them via dedicated switches in the left side of the panel, just beside the sliders.
Pressing 'List' the current User Program list page appear on the display; you can select one of the 8 User Programs listed touching the display or via the 1-8 User Program switches of the panel.
On the display you can browse among the several pages available and using the Down/Up switches on the panel you can increase or decrease the number of the active User Program.
On E-60 the function is the same, but the 1-8 User Program switches of the panel are missing.
