- Press * to increase the contrast on screen
- Press + to reduce the contrast on screen.
Note: le The contrast obtained after using the * and + button is not saved when if powered down. The only way the contrast value, modi-
fied by the * and + buttons, can be saved is via the Contrast menu.
! Contrast adjustment is especially useful when is used in severe conditions (-15°C or +60°C).
! When temperature is above +60°C, the screen is very dark. It is therefore necessary to reduce the contrast by pressing +.
! When temperature is below -15°C, the screen is very light. It is therefore necessary to increase the contrast by pressing *.
