The HFT gives the user the convenience of hands free operation. It can't control the phone's performance (call quality and signal strength). To avoid performance problems, don't put the phone in a metal briefcase or in a purse under the seat.
This guide shows you just a few of the HFT's many features. You will see how to pair your phone to the HFT and then make and receive calls, all using simple voice commands. If you want a complete description of this system, please refer to the owner's manual and quick start guide.
