I just recently did mine... Download the file from the above link. Double click on the file. It's a zipped file, it will self extract. Once it's done, it will have a copuple of files. Connect your scanner to the pc. Follow the instructions from the PDF/text file. ie.. double click the the CPU updater file. You may have to play with the com port settings till you get the right one for your computer.
Let us know how it went. Nick
PS. If you're having trouble finding the update on radio shacks website. Post your email and I'll sent it to you.
