Calling Phone Numbers (Digit Dialing)
To voice dial a number that is not stored in your Contacts list:
1.
Select Menu > Tools > Voice Control > Call [Name] [Type]/
[Number].
2.
Say "Call"followed immediately by a valid string of digits
to be dialed, for example, say "Call 555 6666."
3.
If the correct number is repeated, say "Yes"to dial the
selected number.
Speak naturally and clearly and remember to speak one digit
at a time—1-800 should be pronounced "One Eight Zero
Zero."
