To my knowledge, there is no way to assign scan list 0 using ARC500. If you are talking about how to load V-Scanner folder 0 in the scanner to working memory, here are the instructions. Hopefully, this is the same as my Pro-197. This is done using only the scanner. Press FUNC and then press PROG. Press F1 (Load). V-Scanner folder 0 should be showing. Press F3 (Load). You will get a message "Really overwrite the main memory"? Press F1 (Yes). When the V-Scanner folder finishes loading, Press SCAN. You can now download from the scanner to ARC500 and save the file. If you want to upload to scanner from V-Scanner folder storage in ARC500, ignore this post. I am now going to take a look at ARC500 and will be back to you. Do you have V-Scanner folders stored using ARC500 or do you just want to upload a GR5 file directly to the scanner?
