5SETTING UP THE LCD PROJECTOR
Switch off all equipment before connecting the components. Be aware of
static electricity that may build up, especially in the dry season and when
operating on synthetic carpets. Discharge any static electricity by touching
a metallic surface before you start.
Check for correct mains voltage before powering the projector
(see label close to mains input connector).
Do not cover the air inlet in front or the air outlet on top of the
projector housing as this will block the cooling. A thermal safety
switch will cut off the illumination system if the ventilation is
reduced.
Place the LCD projector on a table at a suitable distance from the
projection screen in order to get the desired size of the projected image on
the wall. Adjust the projection lens for a sharp image by turning the
focusing wheel on the lens barrel. Project on a flat surface screen with high
reflectivity to get a bright and undistorted, rectangular image.Best results
are obtained in a dimmed room with no direct sunlight shining in.
Switch off all equipment before you connect the LCD projector to
the computer, mouse and video source as outlined in the
following chapters. Then apply power first to the LCD projector,
then to the computer and video source for correct operation.

5.2 MOUSE
See the rear foldout when setting up.
Connect the mouse to the LCD projector using the appropriate adapter (5)
as described in the table below. Then connect the adapter (5) to the mouse
cable (1) at the computer end. Finally, connect the mouse cable (1) to the

use of the local computer mouse and the remote mouse. The local and
remote mice should however not be operated simultaneously, as this may
lead to unpredictable positioning of the mouse pointer.
If you have a Macintosh, make sure to connect your Mac mouse adapter
via the keyboard.
The optional PS/2 adapter does not have a Y-split.
APPLICABLE ADAPTERS:

6USING THE LCD PROJECTOR
The LCD projector has a set of connectors and controls that you need to
know in order to operate the device correctly.
6.1 OPTICS
The projection lens is mounted in the front of the projector. The optical
system is designed with a 12 degree keystone correction so that the
projected image is shifted upwards on the wall. This in effect enables the
placement of the projector on a flat table, still getting a rectangularly
projected image on the wall.
Avoid scratching and bumping the lens, as this will reduce the
quality of the projected image. Always re-cap the lens when not
in use!
6.2 ILLUMINATION SYSTEM
The LCD projector uses a 400W halogen lamp for illumination. An
additional lamp (spare lamp) is included in case the main lamp goes out.
The two lamps are mounted in a motorized lamp changer. If one lamp
fails, the other lamp can be shifted in place for continuous operation by
pressing the LAMP CHANGER button on the control panel.
Always replace a defective lamp with a new one after the
projector has cooled down, since the internal lamp house is hot
when in use.

USER GUIDE LCD PROJECTOR

6.3 REMOTE CONTROL
The infrared BatMouse remote control (RC) is the main user interface to
the device. The RC is used to set the LCD projector correctly (to get the
best possible viewing conditions) and to control the presentation.
The figure shows the different keys of the BatMouse.
Set-up should be done once with the application(s) you are running most
frequently. Allow some minutes for the equipment to warm up before
adjusting. Most settings will automatically be memorized individually for
each source for future use.

7FEATURES
The LCD projector has a variety of different features implemented. This
chapter explains each feature in detail.
7.1.1 INTELLIGENT SAFECOOL SYSTEM
The fan operates as long as the LCD projector is switched on. This
ensures a continuous protection against high temperature inside the
projector. The cooling system is designed to minimize stray light and
noise.
7.1.2 MOTORIZED LAMP CHANGER
The projector is equipped with two 400W halogen lamps. If one lamp fails
during a presentation, the spare lamp can be shifted in position and
switched on. Press the LAMP CHANGER button on the control panel to
change lamp. This ensures continuous operation during a presentation.
A LED on the control panel lights when the spare lamp is in use, indicating
that the defective lamp should be replaced.
Always replace the defective lamp as soon as the projector has
cooled down after use
To avoid burns, do not open the rear door to replace a defective
lamp until the unit has cooled down after operation. The interior
of the projector is heated during use.
7.1.3 SET-UP MEMORY
The user controlled set-up, that usually is done when the projector is
connected to a new computer, is automatically memorized for future use.
The set-up information is stored in a non-volatile memory approximately 5
seconds after the last key is pressed.
The memory can store 40 different sources/modes. Several sources are
predefined, while the remaining are available for customer set-up of
sources. See the Technical Data section for compatibility.
Custom sources are stored only if their sync pattern differs from any of the
previous selections. The projector automatically selects a new memory
location.

Most settings are stored individually for each mode, including contrast,
brightness, tune etc. See the remote control table in the Remote Control
section.
