INTRODUCTION ================================================================= This document provides information to help you use Nokia Audio Manager 3.1. It deals with last-minute additions and changes to the user documentation, compatibility issues, and possible problem causes. It is intended to be read before the installation of Nokia Audio Manager 3.1. ================================================================= 2.

SYSTEM REQUIREMENTS ================================================================= To install and run Nokia Audio Manager 3.1, you need the following: - An Intel compatible PC running Windows 98, Millennium Edition, Windows 2000 or Windows XP operating system. - The software is not supported on a homemade PC with Windows 98 installed or a computer which has had its system upgraded from Windows 95 or 3.1 to Windows 98. - Pentium MMC 266 MHz CPU (Pentium 300 MHz recommended), - At least 35 MB of free disc space. Additional space is required for music tracks. - Minimum of 48 MB memory space recommended, 64 MB suggested for Windows 2000 - Display with 800 x 600 pixels and more than 65536 colours, High Colour settings - CD ROM drive SCSI/ANSI X3T10-1048D standard. ATAPI/SFF-8020i standard - Microsoft Internet Explorer is required for the Nokia.com browser window. Windows administrator rights are required in order for the user to run the NAM installation. If the user does not have administrator rights, unpredictable results may occur, and the user will be informed that the NAM is not installed correctly. ================================================================= 4. COMPATIBILITY NOTES ================================================================= 4.1 Copy Protected CDs Due to manufacturer restrictions, in some cases it will not be possible to save tracks from the user's CD. 4.2 Proper USB device handling The USB connection should always be stopped using the Windows system tray, device manager, or similar interface prior to removing a USB-connected device from the PC. After a USB device has been stopped, the Windows operating system and the NAM will not be able to display complete device information. If the user has ?stopped? the USB device but has not yet unplugged it, the NAM will continue to indicate that the device is connected to the PC, but the NAM will not be able to read the contents of the "stopped" device. Windows Device Manager will also indicate that the device is in an unknown state. If the user must complete the removal process by unplugging the device's USB cable from the PC. If the user then reconnects the device to the PC again, it will be possible for the NAM and Windows Device Manager to display the device information correctly. Unplugging the USB cable while tracks are being transferred to the mobile device is considered an "unsafe removal" of the device, and may cause unpredictable results. These results include loss of data, corrupted data, or the PC system may become unstable. Loss of power to any USB device while it is connected to the PC also results in an unsafe removal condition. 4.3 Music file sizes and track length The file size (and length) of music tracks displayed in the NAM depends on how many bytes are in the file as well as the sector size on the disk. Slight differences in reports of these metrics from Windows applications are not unusual. Windows itself displays both the actual file size as well as the sector size utilized in Windows Explorer. For example, if file size is very small then Windows will round up this size to the sector size on the hard disk. These two sizes can both be seen in Windows properties windows. Certain MMC cards and hard disks may different principles for storing data. In the NAM, the file size of each track is calculated mathematically, based on the actual amount of data that is in the file. The file size is computed before the track is stored on the disk. Depending on the type of disk where the file is stored and the PC operating system, there may be a slight difference -- although not more than a fraction of a percent -- in the reported track size. Also, depending on what size information is used by other vendor's PC audio managers to calculate the length of a track, there may also be a similarly small difference in the track length reported through the user interfaces. This will not be more than one or two seconds for a typical music track. ================================================================= 5. LAST-MINUTE ADDITIONS AND CHANGES TO THE USER DOCUMENTATION ================================================================= 5.1 ID3 tag features NAM supports two key items in the ID3 music information tags in a music track. The tags supported are Artist name and Track title. These tags are stored in Unicode format. The NAM will display and allow editing of these two tags. The NAM supports tags found at the beginning of the music file in the following versions of ID3: 1.0, 1.1, 2.2, 2.3, and 2.4. If none of these versions can be found, the NAM will create new ID3 information with the above two key tags in version 2.4 format. 5.2 Interoperability of Music Playlists and Tracks NAM uses *.M3U playlists. To allow use of these playlists in multiple languages, they are saved in Unicode format on the PC. Music tracks created on the MMC card by the NAM or the mobile device are _not_ read-only, and can therefore can be deleted by the NAM. Music tracks in supported formats that are copied to the MMC card by any other means cannot be deleted by the NAM if the file permissions are set to read-only. 5.3 Mobile Device window features The Mobile device window allows you to navigate the entire folder structure of the mobile device Only file types supported by the NAM are displayed in the Mobile Device window. Tracks will be transferred from the PC into whatever folder has the focus in the Mobile Device window. When a playlist is transferred to the mobile device, it is always transferred into the mobile device's playlist folder. When a playlist is transferred to the mobile device, the tracks named in the playlist will be transferred into the folder that has the focus in the Mobile Device window. ================================================================= 6.
