1. YOU: "Save Name"
2. X: "Please say the name"
3. YOU: "Bill mobile"
4. X: "Please say the number"
5. YOU: "2065551234"
6. X: "2065551234" (repeats the number for accuracy)
7. YOU: "Save"
8. X: "Name Saved"

To call "Bill"
After you press/hold the voice button and hear the beep...
1. YOU: "Dial Name"
2. X: "Please say name"
3. YOU: "Bill Mobile"
4. X: "Did you say dial Bill Mobile"? ("Bill Mobile" will be in your voice)
6. YOU: "Yes"
7. X: "Dialing number"
...and the call is executed.

You can always say "Help" after the beep and he'll repeat the available commands.

Hope this helps.
