Notes
The 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.

Press the CONTRAST button:
To adjust the OVERALL , RED , GREEN or BLUE contrast settings, touch and drag
the sliders up and down or for fi ne adjustment, press the arrow heads. To reset a
slider to its midpoint (1.0), press on the numerical value.
The numerical values displayed, ranging from 0 to 2.0 are not absolute, but relative
values. When the
OVERALL slider is used, all three colours on the projected image
will change, but the individual values displayed on the sliders will not.
To maintain optimum overall image contrast and light output, press the AUTO
button. The OVERALL slider will grey out and become inoperable. The actual
contrast settings will be automatically adjusted such that your colour balance
settings are maintained but the optimum contrast and light output will be achieved.
