From user guide:
When properly oriented, the braille cells are closest to you. The Panning keys are at each end of the braille display.
For orientation purposes, there are three slightly raised tick marks located above the braille cells. These orientation marks are spaced by every fifth braille cell. For example, the first tick mark from the left is between the fifth and sixth braille cell.
Moving towards the top and away from you, find a row of three keys, with a wider key- in the middle. The wide key is the Space bar. The Dot 7 input key is to the left of the Space Bar, and the Dot 8 input key is to the right of the Space Bar.
Above the three keys is a navigation pad in the middle, between the Braille Input keys and Space bar. The navigation pad contains four directional arrow buttons (Up, Down, Left, Right) and the Select button.
The six traditional braille input keys are aligned horizontally along the top edge of the face of the display, Dots 3 2 1 on the left and Dots 4 5 6 on the right.
The operating system you are using will determine how you can connect to the reader. We have instructions on how to set up with a Mac or PC.
