LCD screens
Hardkeys are located on the front panel and the sides of the LCD panel and
provide fixed functions that do not change, such as selection of test type.
Softkeys located directly under the LCD change to support the requirements
of each test session.
Test parameter softkeys
Selecting a test mode by pressing a hardkey, causes the required test screen to be
displayed with the appropriate menu of test parameters shown across the bottom of
the LCD. The softkeys are then used in conjunction with hardkeys to navigate
through menus and set parameter values for the selected tests. For example, press-
ing the TYMPhardkey causes the Tymp Diagnostic screen to be displayed.
GSI-developed default parameters for each selected test are displayed on the
lower portion of the LCD above the six softkeys. Alternative choices may be
made by pressing the appropriate test parameter softkey.
Pressing a test parameter softkey causes a new menu of choices to be pre-
sented across the bottom of the screen for that function. The menu structure
for the TympStar Version 2 Tymp diagnostic functions is diagrammed on the
next page as an example.
