During the sessions you will get Closed Caption messages about how much time is left. The first message is the “Opening Message”.

Use the up arrow to expose the Closed Captioning menu and select Subtitle Settings…

Increase the size of the messages so you will see them more easily.

From the Closed Captioning menu you can also choose “View Full Transcript” to open a pane that will display all of the Closed Captioning messages.

There will be 3 more messages, one at Five minutes to go, Three minutes to go, and One minute to go. The meeting will end abruptly at the end of that minute.
