AFAIK it's not certain if warranty extension was ever implemented. And in the end spec derating was cancelled as this was a false alarm.
EDIT, actually extension is valid:
--- Quote --- we are providing an additional 1-year
warranty extension for all the units with SN listed in this service note.
Remark: Product that is currently out of warranty will have its warranty extended to 31st March 2018

i think the unit is around 16 months or so old, but i had assumed it had a 12month warranty! So, back to meet it's makers it goes! :-+

Sorry for revieving a old post, but i've struggled with this exact case as described here.
I've manged to get to the Menu «Follow Support Instructions to Restore Firmware» thanks to the help of all of you!
Can someone provide these instructions? How can you upload the firmware to the instrument once you have booted into the backup Firmware?
Thanks
Chris

Here are the instructions to update via Front Panel USB port...

In this backup FW Mode, you cannot use the Front panel keys unfortunatley. I would need the "support instructions to restore the firmware".
