6 MAKING THE CONNECTIONS
The projector may be connected to different equipment. The following
sections describe in detail how to connect to these systems.
See the illustration on the rear of the quick set-up card on how the various
system parts connect together.
Be aware of static electricity that may build up in the dry season and when
operating on synthetic carpets. Discharge any static electricity by touching a
metallic surface before you start.
Place the projector on a table at a suitable distance to the projection
screen. Select a screen with good reflectivity and avoid direct sunlight
shining in. Place the projector so that the image is visible to the whole
audience, and so that the unit does not obstruct the view. The projector is
supplied with long cables for high flexibility in placement.
Various cables are supplied or optionally available to connect to different
sources. Follow the list below in numerical order for a trouble-free set-up!
1. SWITCH OFF all equipment before making all the connections.
2. COMPUTER GRAPHICS ADAPTER.
Computer graphics adapters use different connectors depending on the
actual computer system in use. Connection to the projector is made
through a basic GA cable and appropriate adapters.
•PC. Use the GA cable directly to connect the graphics port of
the PC to the COMPUTER connector on the projector. If
needed, connect your monitor cable to the free branch on the
GA cable.
•MAC. Use the MAC adapters, as marked, on the computer end
of the GA cable to adapt to the graphics-port connector and
monitor connector on the MAC.
•NEC. Use the optional NEC adapters, as marked, on the
computer end of the GA cable to adapt to the graphics-port
connector and monitor connector on the NEC.

USER GUIDE SVGA LCD PROJECTOR
13
3. SOUND.
The GA cable has a sound input branch at the projector end. Connect
sound from the computer using a standard 3.5 mm stereo jack line cable
(not supplied).
4. MOUSE.
To enable mouse control from the remote control, a connection is made
using a mouse cable and various adapters. Connect the cable directly to
the MOUSE connector on the projector. Connect the appropriate
adapter to the free end of the mouse cable at the computer end as
described below.
•SERIAL (RS 232). Use the serial adapter with a branch for the
local computer mouse. The serial adapter is fitted with a 9 pin
DSUB connector. Use an extra 9 to 25 pin adapter (available
from your dealer) if your computer has a 25 pin serial
connector. Connect your computer mouse to the free branch of
the adapter if desired. With some computers, the branched
adapter may not work. For this purpose, an optional straight
serial adapter is available.
•PS/2. Use the PS/2 adapter that connects directly to your
computer mouse port. Running the computer mouse in parallel
is not possible, unless your computer itself has provision for
two mice simultaneously. You may consider using the above
serial adapter and run your mouse on the serial port instead, in
order to be able to run your local mouse in parallel. This will
require a different mouse driver setting. Please consult your
computer documentation or local dealer for details.
•MAC. Use the MAC mouse adapter to connect to the mouse
port on your MAC computer.
5. MAINS POWER.
Connect the mains cord to the projector and all other equipment in the
set-up.
6. SWITCH ON the projector first, then the computer. It is important to
switch the projector on first in order for correct detection of the projector
as a display and mouse peripheral device to the computer.

7 IMAGE ADJUSTMENTS
This section will aid in adjusting a stable, flicker-free image for best viewing
results.
Use the remote control or the projector keypad to adjust settings, either
directly or through the menu system.
The following list aids in a trouble free set-up of the projector. Try using a
patterned background (tiles, checkerboard pattern etc) when adjusting the
image.
1. ZOOM, FOCUS AND POSITION IMAGE. The projection lens has a
manually adjustable zoom and focus. Place the projector at a suitable
distance to the projection screen, alternatively zoom the image, to
obtain the desired screen size. (See the Technical Data section for max
and min projection distances.) Focus the image and observe that the
picture elements (pixels) become sharp on screen. The projector has
two adjustable feet in the front, so that the image can be shifted to a
desired height on the wall. Tilt the projector body in the desired position
and press the foot-release buttons. If necessary, fine adjust the height
by screwing the feet either direction.
2. RESET in most cases automatically adjusts the image position, width
(FREQUENCY) and stability (TUNE). If RESET fails to adjust the image
correctly, see FREQUENCY, POSITION and TUNE below. RESET is
automatically activated when a new source is connected.
3. SCALE the image as desired if you are viewing a lower (VGA) or higher
(XGA) resolution image. Scaling will fill the viewable area by enlarging a
lower resolution or compressing a higher resolution image. If you do not

USER GUIDE SVGA LCD PROJECTOR
15
scale a higher resolution image, you may choose to PAN around instead
in order to view parts of the image.
4. CONTRAST and BRIGHTNESS may be adjusted according to your
personal taste, the image and the viewing conditions. The controls are
directly accessible on the remote control and on the projector keyboard.
5. FREQUENCY. The frequency controls the width of the image. A wrong
frequency setting can be seen as equally spaced, vertical stripes or
irregularities in the pattern displayed. Press the MENU key, SET-UP,
FREQUENCY and press ENTER. Adjust the value up or down using the
trackball or keyboard cursor controls, observing that the amount of
vertical stripes reduces, until the distortion is gone. You may still have
an unstable image, please see the next section.
6. POSITION the image correctly by accessing SET-UP, POSITION, then
press ENTER and adjust position with the trackball or keyboard cursor
controls
7. TUNE the image for a stable projection. In the menu, select SET-UP,
TUNE and press ENTER. Adjust stability using the trackball.
Set-up should be done once with the source(s) you are using most
frequently. Allow some minutes for the unit to warm up before adjusting the
settings. Most settings will be memorized individually for each source for
future use.

8 USING THE PROJECTOR
The projector has a set of features and functions you should familiarize with
in order to get the most out of using the unit.
Further information is provided in the Advanced Features section.
8.1 REMOTE CONTROL
The remote control is used to adjust the projector for the best possible
image, either directly or through the menu system. It is also used during
presentations for computer mouse control and with special presentation
tools.
The remote control may be pointed directly at the projector
front, where the receiver is situated, or indirectly by pointing
at the projection screen. When pointing at the screen, point
at an angle that reflects the beam towards the projector.
The trackball is by default controlling the computer mouse (if the mouse
cable is connected properly). With some functions, like POINTER, MASK
and in the menu system, the mouse control is disabled.
