Updating CHG 70 N charger

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

In order to update the CHG 70 N charger:
  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.

    In case of cascaded devices the update starts with the last displayed cascaded device and continues in ascending order up to the master device. The update process may take up to 15 minutes. Devices that display dashes are unreadable due to an error.
The firmware of the charger has been updated.
