Virus's and
4.2 Privacy filter / Firewall
If you have a Firewall on your router or a privacy filter/Firewall on your computer, you may need to set the permissions on the Firewall to allow traffic to and from your computer and the 640H. Please see the instructions of your firewall/privacy filter for guidance.
4.3 640H content management
The 640H creates its database of content on your PC/Mac based on the artist, album name, track name and genre of each track. As you rip CD's, the 640H stores the CD contents on the 640H Hard Drive in a series of folders. It does this in the order of Artist, Album and Track Name (track name as a file). If the 640H scans for content from USB devices or over a network, the 640H adds their content to its database based on the file name you give for the MP3s and also their Genre, Artist, Album and Description (Title) tags.
MP3, WMA, AAC and other compressed audio formats have the above tags embedded into them. This allows the track number, year of release, track name, album name and artist name to be stored in the file itself. The 640H uses some of this information when creating its database of stored and scanned content.
When ripping CD's from the 640H, the automatic freedb lookup (freedb is the online service that holds a database of artists, albums and tracks) will fill in the details for you. If you put the information in by hand, the 640H will assign the album name, artist name and genre for each track based on what you enter.
For the 640H database to be accurate when you scan content from USB sticks or over a network, some rules must be observed:
1.Make sure the artist name for each song in the album is the same. If you are ripping a compilation album where the artist of each track is listed individually, then this must be changed to Various, Various Artists etc.
2.Make sure the album name and genre for each track within the album are the same.
3.Make sure each track file name starts with the track number. Tracks
4.A good example of what the data should look like is shown here:
If these rules are not followed, then the 640H will not store each album in its database correctly and therefore will display incorrect information.
If you wish to alter the content of your 640H via a PC or Mac (i.e. names of files, album art, tags etc) then it is recommended to do this periodically (i.e. when you have a large amount of albums that need to be changed) instead of doing it for each album at a time. This is because when you alter the 640H from another device, you have to "Rescan" the 640H via Settings/System/Product/Rescan so the 640H can go over its database to see what has changed and alter it accordingly.
In each folder on your 640H, there are two files; cddb.nfo and attributes.txt. These two files are not to be changed or deleted under any circumstances. They are important files required for your 640H to display information correctly. If any of these files are deleted, you need to immediately rescan the database. Rescan can be found in; Settings/System/Content/Rescan.
4.4 Music transfer limit
When transferring music from a 640H to another device (PC, USB Hard Drive etc) or vice versa, the 640H does this at a maximum of 2000 tracks at a time. If you wish to transfer any content, you can do this by either, album, artist, playlist, tracks or genre.
To transfer music from your 640H to a PC/Mac, or vice versa, you first need to add the PC/Mac as a location on the 640H (see "Adding Content to your 640H from your PC/Mac" sections earlier). You then need to go to the music library and select what album, artist, playlist, tracks or genre you want to transfer. When you have done this, select the "Send to…" button and choose the destination. When you have done this, select "Start" and the transfer process will begin. When the transfer is complete, the message "Music sent successfully" will appear on the top left hand corner of the 640H screen.
If you want to transfer music from your 640H to a USB flash device/external hard disk drive or vice versa, you need to go to the music library and select what album, artist, playlist, tracks or genre you want to transfer. When you have done this, select the "Send to…" button and choose either the "Hard Disk Drive" (for the 640H) or "Portable Device" (for a USB device). When you have done this, select "Start" and the transfer process will begin. When the transfer is complete, the message "Music sent successfully" will appear on the top left hand corner of the 640H screen.
4.5 USB devices
The 640H also has the ability to access content situated on USB 2.0 flash "sticks" and USB 2.0 external hard drives.
Note: Only USB 2.0 certified products with the USB 2.0 logo on them and "Mass Storage Devices" are supported by the 640H. Please either consult the manufacturer of the USB 2.0 product to make sure it is properly certified, or go to www.usb.org for a list of approved products, before purchase. We cannot be held responsible for any incompatibility issues.
To access the USB device's content; plug it into one of the USB ports on the 640H. The 640H will then scan its contents and add it to the 640H database automatically.
4.6 NAS Drives
There is now a new kind of "external" hard drive called a NAS (Network Attached Storage) drive. Even though most NAS drives come with a USB
2.0and Ethernet socket, they are not External Hard Drives. This means that plugging a NAS drive directly into a 640H via either the USB or Ethernet socket will not work.
If you wish to use a NAS drive then plug the NAS drive into a PC or Mac and share it over a network in the normal way (see "Setting up your PC/Mac to share music over a network" sections earlier on). Depending on your NAS drive, you may also need to install drivers on your PC/Mac and go though a specific set up procedure. Please read the instruction manual that came with your NAS drive for guidance.
Note: The NAS drive will need to be reformatted to the FAT32 file system (if it came preset as NTFS) for the 640H to access it.
