Note on naming:
If a 'sub-menu' has further subdivisions, from now on it will be referred to as {function}
main menu. The "CONTRAST" sub-menu for example will be referred to as the
"CONTRAST" main menu. Otherwise it will be referred to as the {function} menu.

6.4.1 Setting the contrast

From the CONTRAST main menu, choose the "CONTRAST" option in order to access
the "Setting the contrast" menu.
Use the F2 and F3 keys to set the display contrast to the desired level and then use the
"DONE" option to return home.

6.4.2 Locking and unlocking configurations

Use the "LOCK CFG" or "UNLOCK CFG" option of the configuration lock menu
respectively 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 other menus are
locked with the exception of the "MIN/MAX", "Setting the contrast" and "UNLOCK
CFG" menus. When the "UNLOCK CFG" option is chosen, the configuration is
unlocked and the menu display continues to the next sub-menu.
