I made some amendments to program 4310 (Barking Chamber) and pressed the Update button to overwrite the factory preset. However, I get an error of "Cannot update: Write Protect". So how do I switch off Write Protect ? I don't see it in SETUP …
you can't update/overwrite/delete factory presets, not disable protection. Just save your tweaked copy in RAM. Presets in RAM can be further updated then.
