I just received my new GD-X6900MH-1JR and can't seem to find out how to change the region from Tokyo to NYC. I downloaded the manual and there's nothing in there about it. I've always been able to figure out how to change it on my other watches, but this one has me stumped. I had no problem with my new Rangeman, but the steps are not the same with this module. Or, am I missing something?
