Important
Operation outside the Damage Thresholds can cause permanent device damage. Damage Threshold does not imply functional operation of the device at these or any other conditions beyond those listed under specifications. If used outside the specifications but within the Damage Thresholds, the device can not be fully functional, and this can affect device reliability, functionality, performance, and shorten the device lifetime.
