Yes,it would be nice if someone could send you a copy of a valid Micro-SD card. Could the data be successfully sent as an email attachment, I wonder. think

Regarding its contents ... that's probably an academic question (as you really just need to get the monitor going again). But I imagine that Philips use that (cheap, easy) technology for the reason you have alluded to:- an easy way to re-configure (and/or upgrade) the MX monitors.

Like you, I would be interested to see what data is meant to be held on the Micro-SD card; but unlike you, I don't have an MX monitor to hand. frown

If you don't inspect ... don't expect.
