Programming ReSound LiNX 3D with Airlink 2.

A significant amount of the Technical Support calls we receive relate to our new ReSound LiNX 3D hearing aids not being detected using the Airlink 2. ReSound Smart FitTM is the fitting software required for ReSound LiNX 3D devices. This software includes ReSound Aventa 3.11 required to program existing devices. Additionally, the most up to date version of the firmware for Airlink 2 is the firmware version 2.15. Updating the firmware to this version ensures compatibility with the latest ReSound LiNX 3D devices.

The steps below have been listed to guide you through the process of the update.
