3.17.6 FUNCTIONALITY
The display screen has been devised as a way to examine data
within the supplied product. You cannot edit settings from this
screen. This can only be done via GenLink. Data has been divided
up into groups and each group is shown as a button on the menu
screen. Touching the button will take you to the main screen for
the group. Some groups such as diagnostics may also have sub
screens associated with them. Each screen has some fixed but-
tons which allow you to either access help text for that screen
(context sensitive help) or return to the main menu (Figures 3.23,
3.24 and 3.25).
