Vuzix Wrap 920AR - Manual (Page 15)

This Control Box provides two cable connectors. The rectangular port is for the cable
coming from the video eyewear and the round port is for the cable going to your
media player.
 Plug the eyewear’s Multi-connect Cable from your eyewear into the matching
connector on the Battery/Control Box.
The black side of the connector tip and the Vuzix imprint face up toward the buttons
on the Control Box.
 Connect a Vuzix compatible composite cable into the Control Box port labeled
“AV”.
Note: Be sure to insert the connector fully into the AV connector. Partial insertion is a common error.
