Hello everyone- I've found the manual for the HD10U- but does anyone know if the manual for the HD1U is available for download?

I have no answer to your question. But from an info standpoint the manuals should be the exact same. If you notice the mickey-mouse look/usefulness of the manual I can almost guarantee that they are identical, except for omitting any info on the XLR audio jacks. From a function control standpoint both cams are identical so your not going to be missing anything from not finding the HD1 manual.

Ken, Thank you- I actually did run into the pdf via another forum- so I've got it- but I don't recall where the d/l was from. Thanks again.

Here's a link to download the HD1 manual from JVC's site:
