If you have attached the Tobii X1 Light Eye Tracker to a monitor using the Mounting
Bracket, do not carry the connected devices by solely gripping the Tobii X1 Light Eye
Tracker or the Mounting Bracket. The VESA mount attachment points may not hold
the weight of the computer monitor, and the devices could break apart and fall, or
topple and fall because of misbalanced weight, causing permanent damage to both.
Tobii Technology will not be held liable for the resulting damage.

4 Assembling the Tobii
X1 Light Eye Tracker
To be able to use the Tobii X1 Light Eye Tracker, you must first install the necessary
software and drivers from the included CD, assemble the mounting equipment for the
eye tracker and attach it properly to your Tobii X1 Light Eye Tracker.
Do NOT connect the Tobii X1 Light Eye Tracker before the installation software has
been run. Connecting the eye tracker prematurely can lead to software compability
issues as the wrong drivers may then automatically be installed by Windows.
The Tobii X1 Light Eye Tracker ONLY works with PC computers running a Windows
operating system (Windows XP and later). It is optimized for Desktop PC use with an
external monitor. If you use it without attaching it to a monitor using a VESA mounting
bracket or adhesive mounting bracket, extra care needs to be taken to perform the
setup correctly for the eye tracker to perform optimally.

4.1 The Tobii X1 Light Installation Guide
The Tobii X1 Light Eye Tracker Installation Guide will guide you through the installation
of the necessary software and drivers for the Tobii X1 Light Eye Tracker, provide
Licensing information and show what monitor is currently set as the primary monitor
in the Windows Display settings. (To be able to use the Tobii X1 Light Eye Tracker
Configuration Guide when having it mounted using the mounting brackets, the
monitor on which the eye tracker is mounted must be the primary monitor according
to the Windows Display settings.)
1. Insert the included CD into your computer’s CD/DVD Disk Drive. The
Installation Guide will open automatically.
2. Follow the instructions within the Installation Guide, selecting Next to
proceed.
Chapter 4 Assembling the Tobii X1 Light Eye Tracker

Tobii X1 Light User Manual

Once the Installation Guide is finished, you need to power off your computer to
mount the Tobii X1 Light Eye Tracker on a mounting device such as the mounting
brackets or a desk stand, and to connect the cables between the Tobii X1 Light Eye
Tracker and your computer.
3. Eject the CD and power off your computer by selecting Shut down on the
Finalize page of the Installation Guide.
If the installation guide did not run on the monitor on which the eye tracker will be
mounted and you are planning to use a VESA mounting bracket or adhesive mounting
bracket, it is highly recommended that the Windows display settings are changed
before restarting the computer. If this is not done, it is not possible to use the
simplfied setup configuration available through the Tobii X1 Light Configruation guide.
Setting the primary displa is done by clicking Start -> Control Panel -> Appearance
and Personalization -> Display -> Adjust resolution, click on the monitor that the eye
tracker will be attached to, mark the tick-box labelled “Make this my main display” and
then click on the “Apply” button.
4.2 The Power supply and the battery pack
Before first time use, the power adaptor or battery pack needs to be assembled, and
if the battery pack is used, the correct voltage has to be set.
4.2.1 Assembling the power adaptor
In order for the power adaptor to be compatible with various power sockets, it is
delivered with a set of interchangeable plugs. Once the appropriate plug has been
selected, it should be attached to the power adapter by pushing the plug down and
towards the cable end of the power adapter in the hole designed for that purpose
(see image below). Once this is done, the power adaptor is ready for use.

4.2.2 Assembling the battery pack
The battery pack consists of two parts: the battery pack and the charger/power
supply. The charger only requires the appropriate power cord to be attached (see
image below).
The battery pack first needs to be set to deliver the correct voltage. This is done by
turning the battery pack so the black, bottom side is visible. At the bottom of the
battery pack is a switch that can be set to either 9V or 12 V. This switch should be set
to 12V in order for the eye tracker to work (see image below).
