13. Adjusting Lighting and Contrast
Pressing key 5 (the right-hand key) when the menu icons are not being displayed brings up the
lighting and contrast menu. The LCD has a number of back-lighting levels that allow the display
to be read in the dark. The appropriate level is selected by pressing keys 1 or 2 to decrease or
increase illumination. Contrast is adjusted in the same manner, using keys 3 and 4 (Figure 10).
Note. The Engine Monitor monitors the temperature of the LCD and automatically adjusts display
contrast as required, therefore it is not likely that a user will need to make a manual contrast
adjustment unless extreme climate changes occur. The menu is exited by pressing key 5. The
lighting and contrast settings are retained after the unit is switched off.
Note. Resetting contrast. If the contrast has been adjusted poorly, you may restore the
factory setting (a central value) by pressing keys 1 to 4 simultaneously. This action does
not change other user-configured settings.
