• The Gratical has four function
buttons that can be assigned
by the user. These include the
four directions of the joystick
(UP, DOWN, LEFT RIGHT).
Function buttons come
preprogrammed but can be
changed at any time.
• To change the function assigned
to each button, select the function
button you wish to change.
From the subsequent menu,
choose the desired function
you wish to be assigned to
the function button. It can
now be activated by
pressing the appropriate
function button on the side of the Gratical without the use of the menu system.
• Function buttons can only be used when the menu is not displayed.
