LCD Contrast Tuning
Extra equipment not needed.
This function is used to calibrate the LCD Contrast (brightness).
Must be done when LCD module is changed and there is considerable difference in the
contrast.
Select Maintenance => Testing => Display Tune
Move the Contrast factory offset slider to reach good LCD contrast.
Both sliders are relative. The Default button resets the bottom Contrast factory offset
slider to default value 41. The Contrast offset slider should always be set to 0% (mid-
dle of the scale), because that setting is visible on the phone screen.
Close the"Display tune" dialog to end tuning. The tuned values are saved automatically.
