Looks like it’s pretty clear that I did actually delete the manufacturer preset after all. I hadn’t seen Tech Note 97 prior to doing the self-tests, so I didn’t know that “Test 4500 All
runs all DSP4500 tests. Loopback adaptors will be needed for some of these. Will erase factory presets and any card in slot. Test 4500 NL Runs all DSP4500 tests that do not require loopback adaptors. Will erase factory presets and any card in slot.”
Feeling really, really stupid. Any suggestions? I also posted a specific question about this under a separate heading in this Forum in the hope that others might see it and offer ideas.
Thanks for any help you can provide.
