does anyone have a Z220S Manual in pdf???

I just found a z220s strobe at a dive flea market. It works nice, but no manual. Does any one have a copy??

Or my question is, do i need a screw in the magnet screw hole if I am not using the feature. i do not want to flood the strobe.

thanks

See http://www.digitaldiver.net/lib_docs/Z220ManualVer11.4b.pdf for a manual on the Z220
