NOTE:
To properly ventilate the device, allow at least a 7.6-cm (3-inch) clearance on the left side of

affected by high external temperatures, system power consumption, power management/battery
conservation configurations, battery fast charging, and software requirements. Exhaust air is displaced
through the ventilation grill located on the left side of the device.
