Introduction

The Multiple Digital Messaging Unit (MDMU) is a micro processor based digital voice announcement system. It outputs prerecorded messages through a public address system. Up to 99 messages can be placed in the units digital memory for queued replay. Up to eight messages can be programmed to play in sequence with timed delays.

Depending on the amount of memory option configured in the MDMU, multiple messages can range from 32 seconds up to 8 minutes 44 seconds in length. Voice and audio messages can be stored into memory through dial-up telephone, microphone interface, or tape input. (The MDMU is programmed by dial-up telephone DTMF tones.)

This guide gives installation, recording, and programming steps. Since messages are digitally stored, and there are no moving parts, the MDMU should give years of uninterrupted service.
