To access contacts stored in the cell phone:
1. Press and hold 
for two seconds.
2. Say “Bluetooth.” This command can be skipped.
3. Say “Voice.” The system responds “OK, accessing <phone name>.” The cell phone's normal prompt messages will go through their cycle according to the phone's operating instructions.
