Your phone features Voice-Activated Dialing. When in a CDMA 
network, you can call up to 20 stored entries by speaking the 
name into the microphone. Using the Voice-Activated Dialing 
option requires that you first train the phone to recognize the 
name of the person you are calling.

Note: Voice-Activated Dialing does not work when your phone 
is in analog mode

 ♦ 

Avoid recording similar names phonetically. If you 

record a similar name to one that is already in memory, 
the phone requests another name.

 ♦ 

Avoid recording in a noisy place.

 ♦ 

Speak clearly and naturally.

 ♦ 

The person who will use the phone should record the 

name. 

 ♦ 

Avoid very long or very short names. Names with two to 

five syllables are recommended.

 ♦ 

If a voice dial entry does not properly connect, you may 

need to record the name and number again.
