3.2 Product care
The front glass of the eye tracker needs to be clean in order to ensure optimal tracking. If dirt
or dust ends up on the front glass, the eye tracker has to be cleaned in a correct manner.
To clean the front glass use a dry microfiber cloth intended for cleaning cameras, camera
lenses, or eyeglasses and carefully wipe the front glass. If unsupported cleaning methods are
used the eye tracker might be damaged.
Warning! Do not use alcohol to clean the front glass, as it may damage the eye tracker!

5.1 Troubleshooting
This section presents solutions to problems that you may encounter when using the eye tracker.
If your problems persist or if you don’t find any solution here, please contact support.
I can’t install Smart Eye Tracker.
Make sure you have admin rights on the computer where you attempt to install Smart Eye
Tracker.
The laptop goes to sleep when I connect the eye tracker to the bracket.
The eye tracker contains a magnet to make sure it attaches to the magnetic holder. Some
laptop models also have a magnet in the lid to make sure the computer sleeps when the lid is
closed. Change the setting so the computer stays awake even when lid is closed. This setting
is found in the Power Options menu in the Control Panel.
There seems to be problem with the connection to the eye tracker.
Try unplugging the eye tracker and plugging it in again.
The framerate is low or fluctuates.
Make sure that the computer is connected to a power source and that a high performance
Windows power plan is used. The power plan can be set in the Power Options menu in the
Control Panel. Create a new power plan and make sure the high performance option is chosen.
