Firmware update process
The easiest way to update instrument firmware is online:
- Provide the instrument with an Internet connection using Wi-Fi or Ethernet
- Access update screen (System settings > Update)
- 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:
- Click on the desired version number below. This is a link to the .lsfw firmware update file
- 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
- 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
- Restart the instrument to be given the option to perform a firmware update.
- Disconnect the USB flash drive once the update is complete
