(except Digital Rights Managed WMA files) NW-HD5: Intelligent follow turn display A seven-line large LED window with bright backlight combined with the novel concept of the follow turn feature of the display delivers real intuitive operation. The display graphics shift and change position depending on how users hold the NW-HD5 Network WALKMAN to provide smooth visibility. This 'follow turn' feature uses G-Sensor technology to automatically detect the horizontal or vertical position of the device and consequently changes the position of the display graphics as well as that of the function buttons.

The battery is replaceable and easily accessible and can be replaced by users without the need for a visit to a service centre.
