Changes for CapTel 800i / CapTel 840i Users
A recent ruling by the FCC requires changes in the way that all IP-based captioned telephones work. Effective March 7, 2013, you will need to press the CAPTIONS button to turn captions on at the start of every call. The captions will no longer come on automatically. When people call you, you will need to turn captions on by pressing the CAPTIONS button in order to see captions of the call.
The CAPTIONS button will turn off again every time you hang up the handset.
