The jack where you insert your headset is located on the right side of the device. Be sure to press the headset lead in firmly to secure the connection. Caution! Always insert (or remove) your headset before making or receiving a call, or you risk disconnecting the call. If you think you'll be using the phone while driving, insert the headset before starting the drive. USB Port The USB port is located on the right side of your device, between the power and headset jacks, as shown in the illustration below. If your device should ever need recovery software installed (this would have been diagnosed by Customer Care), you would need to connect your device to your desktop or laptop computer using a USB Mini-B type cable.
