I'm on ancient LH100 so nothing to suggest beyond the basic trick for devices with firmware of 'leave off power for 24 hours, and retry'.
However, fear not the warranty covers you.Can the retailer offer any advice? If not, another retailer I would try is 'Coastal DCC' as Kevin Dickerson is a mine of information. The backstop is A and H models as soon as they reopen 10 am Tuesday for advice, on the basis that they will ultimately end up handling any warranty claim as the UK Lenz agent.
