Large buttons on the front of the DMP-100 control all major functions. The buttons can be deactivated with a hold switch to ensure that music is not interrupted accidentally. A five-band equalizer allows you to customize the sound, or you can choose from one of many presets. The DMP-100's scrolling LCD screen provides track information including song title and artist. Additional menu commands allow you to delete tracks or change player settings without the player being attached to a PC. Available memory and other information can also be displayed.

D-link's intuitive MP3 and file management software writes and reads data from the DMP-100's internal memory or SmartMedia memory cards via a parallel port interface.

The DMP-100 runs on a single AA battery. The box includes an installation/software CD-ROM, a parallel port cable, a battery, earphones, and a manual.
