Subject to availability.
10. The listed battery life is obtained by simulating watching video clips stored on the mobile device. The test clip loops and
continues to run, without interruption or any other inputs, until the battery is drained. Stated battery life is for
comparison purposes only. Actual battery life varies by model, configuration, applications, power management settings,
operating conditions, video clip format, and features used. A battery's maximum capacity decreases with time and use.
11. Bundled software may vary depending on hardware configuration, OS and regional availability.
12. Some models/configurations have a Microsoft Product Identification (MPI) card in the box, which contains a product key
to activate the full version of Microsoft Office 2013 Home and Student Edition. If your device does not include an MPI
card, you will need to purchase a product key separately.
As a phenomenon known to thin-film transistors (TFTs), liquid crystal displays (LCDs) commonly exhibit a small number of discoloration dots, as so-called "non-conforming pixels." This phenomenon is a limitation of TFT LCD technology, not a product defect,
and as such is not covered by Acer's warranty. In a continuing effort to improve the quality of our products, information in this document is subject to change without notice. Images shown are only representations of some of the configurations available for
this model. Availability may vary depending on region.
