Vuzix Wrap 920AR - Manual (Page 26)

Control Box
The Wrap 920AR includes two Control Boxes; one is battery powered for
connecting to media players and the other includes hardwired USB and VGA cables
for connecting to a Windows based personal computer. Both units look the same,
other than cabling, and both employ the same control buttons.
