Notes
The eight buttons of the Main
menu are always visible at the
bottom of the display.
To go back to a previous menu
option that is no longer visible,
call up the menu again using
the appropriate Main menu
button.
The contrast, brightness and
gamma controls in the Image
menu are all interactive, so
settings made with one control
may directly affect the setting of
another control.
All these controls allow extreme
settings to be made. However,
in normal use, it should never
be necessary to set any of the
controls far from midpoint.
If in doubt, reset the contrast,
brightness and gamma controls
to midpoint, then make your
adjustments in small steps.
Better still, use the AUTO
feature.
