Touch Screen Firmware V1001 (12 inch) and V1000 (15,17,19,24):
For Maritime Multi Display (MMD) / Industrial Standard Display (STD) units the touch screen signals are routed through
the display unit via the USB port and can not be controlled / detect status by the unit itself in any way. It means that even
if the unit was turned off by the front bezel Power ON/OFF function, the touch screen is still active and it will still send
touch screen signals through the pipeline.
This can be an issue to consider when you are cleaning the front glass. In order to avoid sending touch screen signals,
you have to either physically cut power to the unit, making sure that no lights illuminate, or disconnect the USB cable
physically from either computer or display unit. You may also disable the touch screen functionality from within the
Operating System (OS) or via customized functions from within applications running on the external computer you have
connected.
Touch Screen Firmware V1002 (12 inch) and V1001 (15,17,19,24,26):
Issue described above has been solved. For Maritime Multi Display (MMD) / Industrial Standard Display (STD) units
regarding cleaning of front glass, you have to be aware that in order to avoid sending touch screen signals to a
connected computer, you have to turn off the Display unit (via its front Power Symbol) and clean the front glass.
When done cleaning, simply turn on the Display again and Touch Screen controller is automatically re-activated.

Recommendations” chapter earlier in this manual.
