Important Note
Do not operate the PROTOUCH-WIDE outside of the recommended operating conditions. Otherwise lifetime and
performance will degrade. Operating the board and the display outside of the absolute maximum ratings may damage
the hardware.

General Recommended Operating Conditions
To ensure proper operation of the device keep inside temperature below 70°C.
Operation at

+0
°𝐶
inside temperature is only possible during 240 consecutive hours.
For this the temperature sensor on the SL8 board can be used; see board documentation for
details
Important Note
Maximum ambient temperature is highly dependent on mounting, air flow and CPU/GPU load; with the
Intel Thermal Monitoring
Technologies
the processor automatically reduces the internal CPU when the critical thermal trip points are reached to prevent
damage.
