I'm filling in the insurance details and they want to know serial number. I assume that one of the two numbers on the label is the one I want. Which one is it or, if it's neither of those, where would I find it?

Thanks

I think it's the bottom one. The top one looks like a model number.

The upper number is the model number. The lower one is the serial number

Thanks

It sounds like maybe I've put the model rather than serial numbers of my recorders. I'm pretty sure they don't have their own individual numbers anywhere though. There's nothing written on them or their cases.
