CAUTION: To properly ventilate the tablet PC, allow at least a 7.6-cm
(3-inch) clearance around the sides of the tablet PC.
The tablet PC uses an electric fan for ventilation. The fan is
controlled by a temperature sensor and is designed to come on
automatically when high temperature conditions exist. These
conditions are affected by high external temperatures, system
power consumption, power management, battery conservation
configurations, battery fast charging, and software applications.
Exhaust air is displaced through the ventilation grill located on
the left side of the tablet PC.
