Here is the procedure I used;
Do an freset to reset to factory defaults. Make note of your current settings.
Connect with Uprecise. Do an unlogall for COM1, COM2 and COM3.
Use the update function in Uprecise. I had to do it twice before it worked. Some of the upgrade GUI is still in Chinese even though I have the GUI set to english. I cut and pasted them into Google translate when needed.
Here is version 9984.
