USER GUIDE
9.1.8 SOURCE 1/2/3
These keys select between the 3 analog RGB inputs. Only one input can
be active at a time. All three inputs have the same properties and can be
used for either computer/workstation or RGB video sources.
The Projector defaults to input source 1 at power on. If no signal is
connected, the message NO SOURCE appears on the screen.
9.1.9 FREEZE
Press the FREEZE button on the RC to lock the image displayed. This
feature is useful if you want to make changes locally on your computer that
should not be presented to the audience. Press FREEZE once more to
resume on-line operation. Any other key pressed will also release
FREEZE.
9.1.10 BLANK
Use the BLANK key on the RC, if you temporarily want to suspend the
display of images. The BLANK key is a toggle function, and the screen
goes blank when activated. Any key pressed will release BLANK.
9.1.11 REAR
The projector can be set to project a mirrored image for rear projection.
Rear projection is used when only the actual image is displayed, without
showing the projection equipment. A special transmissive screen is
needed. A typical application is in exhibitions. REAR is a toggle function on
the RC.
9.1.12 FREQUENCY
This setting is provided for adaptation to Workstations and special
graphics adapters that are not recognized automatically by the projector.
An incorrect frequency setting can be seen as an image to wide or too
narrow, combined with vertical, unstable bands. To better see this effect,
fill a large portion of your screen with a 50% grey pattern (alternating black
and white pixels). Make sure that Expansion/Compression is deactivated
i.e. your image is viewed in default 1:1 mode. This is done by pressing the
SCALE key on the remote control. Press the FREQUENCY keys left or
right to adjust the setting until all vertical banding disappears. The final
setting is stored individually for each source.
9.1.13 POSITION
Due to minor variations in graphics adapters, the horizontal and vertical
position may need adjustment. Press POSITION, then use the cursor keys
to position the image. The position is stored individually for each mode.
