Firmware update process

The easiest way to update instrument firmware is online:

  1. Provide the instrument with an Internet connection using Wi-Fi or Ethernet
  2. Access update screen (System settings > Update)
  3. The instrument will detect the latest firmware version, follow on-screen prompts to download and install the update

Updating an offline instrument is accomplished with the following steps:

  1. Click on the desired version number below. This is a link to the .lsfw firmware update file
  2. Copy or save the .lsfw file onto the root directory of a USB flash drive. Make sure it is the only .lsfw file in that location
  3. Plug the flash drive into the USB-C port on the back of the instrument, if you don't have a newer flash drive with a USB-C connection, use the adapter that was supplied with the instrument
  4. Restart the instrument to be given the option to perform a firmware update.
  5. Disconnect the USB flash drive once the update is complete
