Cleaning the touch screen
We recommend using a dry microfi ber cloth to clean the touch screen
Cleaning the dust fi lter
For safe and reliable operation, the dust fi lter of the front panel behind the grilles should be removed and
cleaned regularly to ensure maximum airfl ow through the device.
To clean the dust fi lter, the panel can be removed by unscrewing eight M3 TX10 screws on the top and
the bottom of the panel. If you would like to completely replace the fi lter, you additionally have to remove
the display by unfastening the four M3 TX10 screws.
Please be very careful with the FPC cable when removing the display! Please use original fi lter sets
provided by sonible.
Note: If the dust fi lter is not maintained there will be safety risks. There is also a risk that the unit will
malfunction since it is dependent on constant airfl ow from front to rear. If the dust fi lters are not clean and
the unit malfunctions, any resultant problems will not be covered by the warranty.
Feel free to contact sonible by email at:
Wipe the screen with moderate pressure! Never spray a cleaning agent or any other liquid
directly on the screen as it could penetrate the device!
