First make sure your DCP has captions The file will have a CC next to it
First Turn on the Phone Type Device that displays captions This is located in the A/V closet in 4C. There are actually 3 buttons but we should only need to turn on using this one?

At this window choose Connect
Connecting process will take a second
The device will show >Connected and then choose >Closed Caption
The captions will be unavailable till Play is selected on the DCP timeline
Then captions will show on the device

For reference make sure the captioning server is on and green??
