Users can also fine-tune the text on the screen thanks to eight adjustable font sizes and a choice of six font styles. Screen contrast and brightness can also be adjusted for improved viewing in all types of lighting conditions.

Other features include ten built-in translation dictionaries (including French, Spanish, German, Italian, and Dutch)and the ability to display a range of digital formats, including the popular EPUB eBook standard plus PDF and TXT documents.
