In the past, I've tried searching these forums and when I've had no joy, I've ended up copying the log(s) (removing any sensitive info) and posting on these forums to see if anyone else has already had the particular type of event.
Thank you DS. I was surprised that no one had queried the content of the Log before and that Google turned up so little information. I think I will ask the moderators and also see if I can get any further by searching for information on the firmware.I will update this thread if I get anything useful. This is likely to be delayed for 2-3 weeks.
