The need for translation is registered via each individual participant's BCC Profile.
Parents can register for their children.

If the need is registered once, it is saved for future conventions, and can always be changed via the profile.

The need is registered via the person icon at the bottom of the page. 

Register needs
  1. Connect on Wi-Fi: MobileConnect
  2. Download the latest version of the Sennheiser MobileConnect app
  3. Open the app and select the language for translation.

NB: We recommend using the BOSCH units that are on loan, rather than the app solution due to the difference in quality.
