I cannot read or use the Settings menus because the Closed Caption text over-writes the Settings. Unbelievable thoughtlessness. Do NOT write Closed Caption text to the screen when we are using any Se...
What remote do you have? Sometimes there are shortcuts.
For example, I have the XR11-RF. (It's hard to read its model number because it's stamped with tiny, white font over gray on the rear-bottom of the remote.)
On this remote, I press the B button and it takes me to the Accessibility Settings. The top option is CC.
However, if I quickly press the B button twice...as if I were double-clicking a computer mouse...it'll bypass the menu page (Accessibility Settings) altogether and only turn CC on or off. You'll have to practice the "double click" to perfect it.
