Sony SGPT11 - Manual (Page 32)

Adjusting the Cradle Angle
You can adjust the cradle angle according to how you use your tablet device by sliding the cradle foot to its upper or lower position.
Slide the cradle foot to its lower position to use your tablet device as a photo frame or a table-top clock. Slide the cradle foot to its
upper position when operating the touch screen or connecting a keyboard (sold separately).
Note
When using the cradle foot at its lower position, run the AC adapter cord through the cutout of the cradle foot to prevent the
cradle from falling over.
