What is it with companies selling electronics without instructions? I like the part where Caldwell says to get on its website for information on operating/editing the phone screen (connected via Bluetooth). Damned if I can find any instructions on working with the screen on that website.

I have discovered a few things by perusing various shooting sites and reading discussions asking the same questions I have but it's a plodding process.

I found how to delete a group from the screen, except I didn't. Hold finger on the group you wish to delete for a few seconds and a trash can will come up. Great!
Group 1 was the first I had tried and it was full of zeroes because the Bluetooth had not paired. Held my finger on group 1 and up came the trash can. Touched the trash can and group 4 deleted. Damnit! I wanted to have that group remain. I then fingered group 2, and trashed group 3. Aaaarggghhh!

Bugs. Needs debugging I guess.
