You are correct, jetBlue F/A's perform all the announcements, there are no automated announcements on JBU's aircraft.
The CIDS panel is a smaller panel to the left (outboard side) of the Flight Attendant Panel (FAP). The FAP is what is used to adjust the cabin lighting (including turning on or off the passenger reading lights) as well as adjusting the volume of any passenger entertainment system. Currently with JBU aircraft there is only the Direct TV which is only controlled at the FAP for "ON - OFF", volume, channel selection, contrast are all individually controlled at the passenger seat. Some of the JBU a/c are provisioned for an additional entertainment system, but is not currently utilized.
