2.4 Other Menu Controlled Functions
There are eight ‘sub-main’ menus that can be accessed through the MORE option of the
Main Menu. A ‘sub-main’ menu contains three options. The first option is unique to the
function. The second and third options of a ‘sub-main’ menu are always the same. The
NEXT option leads to the next ‘sub-main’ menu and the DONE option returns home . For
the last ‘sub-main’ menu the NEXT option wraps around to home. See Figure 4 for a
detailed mapping of the menu structure.
A note on naming convention:
If a ‘sub-main’ menu has subordinate menus, it will henceforth be referred to as
{function} Main Menu. E.g. the display contrast sub-main menu will be called the
Contrast Main Menu. If not it will be called the {function} menu.
2.4.1 Setting the Contrast
From the Contrast Main Menu choose the CONTRAST option to access the Contrast
Adjustment Menu.
Use the arrow keys to adjust the display contrast to the desired level and then use the
CONTRAST DONE option to return home.
2.4.2 Locking and Unlocking Configurations
Use the LOCK CFG or UNLOCK CFG option of the Configuration Lock Menu to lock or
unlock the display configuration.
When the LOCK CFG option is chosen the menu display returns home and the CONFIG
option on the Main Menu indicates that it is locked. Also all menus are locked out with
the exception of the Contrast Adjustment menus and the Configuration Lock Menu.
When the UNLOCK CFG option is chosen the configuration is unlocked and the menu
display continues to the next sub-main menu.
2.4.3 Saving and Recalling Setups
The calibrator will automatically save the current set-up for recall at power-up.
Additionally 5 set-ups can be accessed through the SETUPS menu. Select the SETUPS
option from the Setups Main Menu.
Choose SAVE to save a set-up , RECALL to recall the set-up, or DONE to do nothing and
return home.
