Interesting, Alex!...
I'll try this.
Though when I do an update, I always use 'puf cp3_1.8001.0214.puf all' command, which I *Assumed* was the same.
I'll try it tonite an update the post...
Also FYI, I thought i had posted this but a friend was thinking that it might be the internal 'watch' battery that backs up the unit. since this unit is 1-+ years old, that seemed like a possibility...
Unfortunately upon checking, the 3V lithium battery had a voltage of 3.01V !!!? so that doesn't seem to be the issue...
