Rexton Online: For providers specializing in Rexton technology. 2. The Connexx Update Manager

If you already have an older version of Connexx (such as version 8) installed, you do not usually need a fresh download link. Open your current software.

Locate the Connexx Update Manager in your system tray or within the "Help" menu.

Check for updates to automatically migrate to the latest version of Connexx 9. 3. Sifit and Rexfit Databases

The software itself is a shell; you also need the specific "database" for the brand you are fitting. For example, Signia requires the Sifit database, while Rexton requires Rexfit. These are often bundled in the main download or available as add-ons within the Update Manager. System Requirements

Before initiating the download, ensure your PC meets the following specifications to prevent lag during the fitting process:

Operating System: Windows 10 or Windows 11 (64-bit recommended). Processor: Intel Core i5 or higher.

RAM: Minimum 8GB (16GB preferred for smoother multitasking).

Storage: At least 5GB of free space for the software and patient databases.

Hardware Interface: A compatible programming link such as Noahlink Wireless, Hi-Pro, or ConnexxAir. Installation Best Practices Issue 2: Software Crashes on Startup

Backup Your Database: Always back up your Noah or Connexx patient database before upgrading software versions.

Run as Administrator: Ensure you have administrative privileges on your Windows machine to allow the installer to register necessary drivers.

Check Hardware Compatibility: Ensure your programming interface (like Noahlink Wireless) has its own drivers updated to work seamlessly with Connexx 9. Troubleshooting Common Issues

Download Interrupted: Disable your firewall or antivirus temporarily, as some security programs flag medical software installers as "unknown."

Missing Hearing Aid Models: If you cannot find a newer hearing aid model in the software, run the Update Manager to ensure you have the latest Sifit or Rexfit data pack.

Connection Errors: If the software won't detect the hearing aids, verify that your Noahlink Wireless is plugged into a USB 2.0/3.0 port and that the hearing aids have fresh batteries or a full charge.

💡 Pro Tip: Always keep the Connexx Update Manager set to "Auto-Check" so you are immediately notified when new features or security patches are released.

Issue 2: Software Crashes on Startup

  • Cause: Corrupted user profile or missing VC++ redistributables.
  • Fix: Run C:\Program Files (x86)\Siemens\Connexx 9\RepairTool.exe. If that fails, uninstall, delete the registry key HKEY_CURRENT_USER\Software\Siemens\Connexx, and reinstall.

Part 10: Final Checklist – Before You Download

Before clicking that download button, ask yourself these seven questions:

  1. ✅ Do I have a valid Signia professional account?
  2. ✅ Is my computer running Windows 10/11 (64-bit)?
  3. ✅ Do I have a licensed programming interface (Noahlink/Hi-Pro)?
  4. ✅ Is my hardware activation dongle present and up-to-date?
  5. ✅ Do I have at least 5 GB of free SSD space?
  6. ✅ Have I backed up my existing Connexx 8 database (if upgrading)?
  7. ✅ Am I legally permitted to fit hearing aids in my jurisdiction?

If you answered “No” to any of the above, pause. Contact Signia customer support or an authorized distributor before proceeding.

3. AutoCheck 2.0

A self-test feature that verifies the hearing aid’s receiver, microphone, and battery in under 15 seconds. This reduces returns due to “dead” devices.

Step 2: Disable Antivirus Temporarily (For Installation Only)

Some antivirus programs flag specific Connexx drivers (especially the NOAH System Module) as false positives. Temporarily disable real-time protection only during the 15-minute installation window. Re-enable it immediately after.
