Upgrading the 40 ST software is carried out entirely via the unit itself and the BluOS app. You are not able to upgrade using a USB key as is available on the 40 AMP & 40 CD.

If you wish to progress with the update (recommended), please follow all instructions on the display and the BluOS app until the upgrade has completed.
