Remote Control Elements
The DMP230 includes an IR (infrared) remote control. For proper operation, a line of sight between
the remote control and the sensor on the DMP230 (17) is required. The IR remote does only control
the basic functions of the DMP230 and as such adds convenience to the operation, but does not
replace the front panel control on the unit itself.
Transport Controls. In Media play mode, the 4 transport control buttons allow you to start and
32
pause a track, and further skip to the next track or back to the beginning of the current track.
These controls are inactive in FM mode.
Source button. Toggles the program source between Media play and FM Tuner. If FM Tuner is
33
chosen as the program source, the display's FM Mode indicator (28) is lit while the media
replay related indicators (29/30/31) are disabled. Further, the media replay related user
interface elements (13/14/15) are disabled and the functional assignment of the navigation
controls (11/12) is changed.
Mute button. Toggles between muted and un-muted output of the DMP230.
34
Volume control (up/down). Allows you to set the required audio volume.
35
FM preset station buttons. Allows to remotely activate the stored FM station presets in the
36
DMP230. These buttons only work in FM mode and are disabled in Media play mode. Note
that manual tuning via the IR remote control is not possible,
Notes on files, folders and data conventions
The DMP230 is a hardware player and as such subject to various restrictions, which are useful to be
aware of:
Media Memory types. The DMP230 only works with SD cards and USB sticks up to 16GB of size
which are formatted in FAT32 file system and contain a maximum of 2000 files. The DMP230
does NOT support larger memory sizes, external hard disks or any media with NTFS formatting.
Media File types. The DMP230's replay ability from solid state memory media is limited to MP3
files in MPEG 1 Layer 3, MPEG 2 Layer 3, MPEG 2.5 Layer 3 standard, with sample rates of
128/160/192/224/256/320 kbps + VBR. Any other files existing on the solid state memory
media will be ignored and are not available for replay.
File/Folder Structure. The DMP230 only allows a two-layer folder structure on the solid state
media memory, meaning a root layer and a folder layer, but not any cascaded folder-in-folder struc-
tures. Such subfolders will be ignored and their content is not available for replay. Playable files
located in the root layer are displayed in a folder named "ROOT" although this folder does not physi-
cally exist on the solid state memory media.
Folder Sorting. Folders are displayed in the sequence of their creation dates on the solid state
memory media. If a specific sequence is needed, then the folder shall be created in this sequence
on the memory media before copying any MP3 files into them.
File Sorting. Files are sorted alphanumerically, but due to file system limitations, the sorting is
limited to the first 8 digits. This may in some cases - where the first 8 digits are identical - lead to
a random-looking, not alphabetical sorting sequence of files.
File system cache. In order to allow relatively quick access to the file directory during navigation,
the DMP230 loads a copy of the file directory into its own memory upon insertion of the solid state
memory media. This loading process requires some time, during which the display shows a count-
down. The time required is about 4 seconds per 100 tracks with a maximum of 2000 tracks
(meaning Max. 80 seconds loading time).
Displayed File/Folder names. MP3 files are displayed with the first 30 digits of their file names in
a scrolling manner; digits exceeding the first 30 will be ignored. Note that the display data is the
file name and NOT the ID3 tag of the file. Folders are displayed with the first 10 digits of their
names, any exceeding digits will be ignored.
