FOCUS
To select Focus press LENS until the Focus dialogue box appears on the screen and
then make any adjustments using the ï and ð cursor buttons.
Focus adjustment starts very slowly and may not be immediately obvious, therefore
the cursor buttons should be held down until the focus visibly changes. To achieve
optimum focus it may be necessary to repeat the adjustment a couple of times until
the operation of the feature feels comfortable to use.
LENS SHIFT
Adjusts the horizontal and vertical position of the displayed image relative to the
projector. To select Lens Shift press LENS until the Lens Shift dialogue box
appears on the screen. The horizontal shift can then be adjusted using the ï and ð
cursors. The vertical shift (rising/falling front) is adjusted by using the ñ and ò
cursors.
Vertical and horizontal shift can be used in combination, however the extent of their
individual ranges will be reduced depending on the amount of shift used i.e. vertical
shift is maximised when horizontal shift is centred and vice versa. When the extent
of the range reaches its limit, it is possible that there will be a slight distortion of the
lens position which may result in additional flare. If this position is reached, reduce
the lens shift until the distortion is removed.
