Using Automatic Redial
To automatically redial a number when you get the cellular system busy signal (when Snd to rEdiAL appears), press 
SND so rEdiAL appears. The phone automatically redials the number at regular intervals for up to 4 minutes or until the call goes through.
If the call goes through, the phone rings once to alert you. Simply begin your conversation as usual when the other par- ty answers.
If the call cannot be completed within 4 minutes (and Snd to rEdiAL appears again), you can press SND again to repeat the redial cycle or END to end the call.
