Updating SpeechLine Digital Wireless link

The latest firmware versions are available via the internal update server of the Sennheiser Control Cockpit.

In order to update the SpeechLine Digital Wireless link:
  1. From the Device List, select the device whose firmware you want to update (see Devices view).
  2. Open the Device Settings menu of the respective device.
    The dialog Firmware Info indicates the available firmware versions.
  3. From the drop-down list, select the firmware version you want to install.
    To add a manually downloaded firmware, click on Add firmware file and select the downloaded file.
    Firmware versions downloaded automatically by the Control Cockpit are marked via update server. Firmware versions downloaded manually by yourself are marked added manually.
  4. Click on update.
    The firmware of the paired transmitter is not updated automatically. You first have to confirm the update for the paired transmitter.
The firmware of the receiver is updated.
Make sure to update only one transmitter at a time. Updating multiple transmitters simultaneously in the same frequency range may produce interferences which may cause the update to fail.
