It is also possible to view images on a TV or other display via an accessory, such as the Bluetooth Media Viewer MMW-100.

Audio quality

The phone uses an algorithm that repairs lost audio packets. When needed, a new packet is inserted with content based on previous packets. This, in conjunction with re-transmissions, the high sensity and high output power radio will enhance the audio quality compared to a standard Bluetooth device.

File sharing

By using the Server role of the File Transfer Profile, the phone enables the user to use a computer to manage content files that reside in the phones file system. Most computer Bluetooth applications provide an explorer like user interface for the file transfer service. When connecting to the phone, the computer application will show some of the folders that the user can find under the My Items icon on the phones standby screen, i.e. Pictures, Sounds, Videos, Themes and Others. The content in the Games and Applications folder is not exposed in the file transfer server. Opening one of these folders will show a list of files related to that folder, e.g. images in the Pictures folder. Using the computer application the user can now: retrieve files from phone to computer, delete files from the phone and transfer files from the computer to the phone using the normal drag and drop mechanisms provided by the computer.

Media viewing

The phone can send images and sounds to a media viewer device, for example the MMW-100 TV adaptor accessory. The user can also conveniently run a slide show on the TV showing a set of phone camera pictures for family and friends. After selecting an image in the Pictures folder under the My Items icon, the user can select the Remote screen option under More. The phone will then connect to a Bluetooth device that can receive images and when the user then selects View, the image is transferred to the remote screen and dis- played. When the user then selects another image, that image is transferred to the remote screen and displayed.

Remote control

By using the Bluetooth HID (Human Interface Device) Profile v1.0, the phone is able to act as a HID device. This means that when connected to a computer, the phone works like a combined keyboard and mouse. By assigning specific combinations of computer keyboard key presses to each key on the phone keypad, the user can use the phone as a remote control device for computer applications.

The phone keypad is configured for control of a certain computer application through a special type of HID configuration file consisting of an XML file for the keypad and an image for the display. HID configuration files can be dowloaded into the phone using the normal file transfer mechanisms. Users can even modify the files themselves on their computers. A few configuration files pre-loaded in the phone enable the user to navigate on a computer desktop and control presentations and media players.

System Functions

User Settings

The following keys can be configured through the HID configurations files: 0-9, #, * and volume up and volume down. For each of these keys, a UsageID from the HID usage tables can be assigned.

The navigational key and the two action keys are not configurable, they always provide functions for moving the mouse and performing right and left mouse clicks.
