INTRODUCTION.

The BlackBoxAV DMS2 Messaging System is intended to play audio messages on demand into either stereo headphones or low power external speakers.

Up to 16 messages can be held on the system and these are accessed via buttons connected to screw terminals on the unit.

The audio messages are encoded to the MP3 format using a computer running standard software, and then downloaded to a MultiMedia Flash card.

The purpose of this software is to allow simple access to the MP3 files, create an index file for the firmware within the DMS2, and to facilitate the download process.

You should switch off the DMS2 before removing and reinserting the MMC card. The card can be accessed by removing the small metal plate at the rear of the DMS2.

After reprogramming the MMC card and replacing in the DMS2, you should ensure that the 'READY' message is displayed on the DMS2 a few seconds after the 'INITIALISING' begins.
