The DME is an MP3 Message on Hold player designed for business messaging and music on hold applications. Bespoke messages and audio files play from an SD card which can be preloaded with content and remotely updated without physically accessing the device. The Securefresh feature achieves this by connecting to the internet from within the end-user network without need for potentially insecure access from outside their local network.

The DME can be programmed to play messages at specified date and times. Example applications include time programmed Christmas, weekend, or vacation messages, and changing messages for different times of day such as inside or outside business hours, or for days of the week.

Free software is available for all Natcomm digital audio products to prepare and transfer files to an SD card. A unique feature is the ability to encrypt files so that creative content cannot be easily replicated or played elsewhere. Files are automatically numbered to set the desired sequence of play.

The DME has a 3.5mm stereo jack for audio output and a volume control pot. Boot-up, Securefresh updates and play information is displayed on an LCD. The package comes with an SD card, power adaptor and user guide.
