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.
