For example, the store people set the DTMF to "Long". What is DTMF and what does it mean when it's set to Long? I know what DTMF stands for but the definitions I got online didn't make much sense to me.
Also, along the top of my screen, there are a row of mini-icons. There's one that I can't seem to figure out what it is. It's sitting next to the signal strength indicator. It's a "E" on top of ",,", one "," is green and the other is red. I have no idea what it means.
And the smart key...can I turn it off? I don't mean just to hide it, I want to turn it off.
So if anyone knows of a good place I can go to for help, I'd appreciate it if you let me know. Or if anyone has the answers to my quesitons above, I'd appreciate that too!!
