HT3000 HOST
FREQUENCY & PHASE
These adjustments, available for progressive signals and
for signals from a PC, ensure correspondence between the
number of pixels making up the signal and the number of
pixels that make up the projected image.
It is not normally necessary to adjust these parameters
because the system checks the input signal and automati-
cally sets the most suitable values. If however the image is
disturbed (loss of resolution between equidistant vertical
bands or instability and lack of detail in thin vertical lines) it
may help to ask the system to rerun the input signal analysis
and set the best parameters by requesting the automatic
adjustment function with button A on the remote control
or AUTO on the keypad. If the automatic procedure fails to
achieve the required effect, enter the frequency and phase
values manually and move sufficiently close to the screen to
observe the effects of the adjustments.

ORIENTATION
Reverses the image vertically and horizontally to best fit the
installation: i.e. desktop front, ceiling front, desktop rear and
ceiling rear.
KEYSTONE
To achieve the best image quality, we recommend install-
ing the projector on a surface which is perpendicular to the
screen. If the image slopes left or right, adjust the feet on
the bottom of the projector to obtain a level position, lining
up the base of the projected image with the base of the
projection screen.
If this adjustment is insufficient to centre the image on the
screen, tilt the projector and use the Vertical keystone adjust-
ment to compensate for the resulting distortion.
