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.

Push the Battery slide switch to the ON position.  
The MDMU is now ready to record and play meassages.  
NOTE: The internal battery  
maintains the recorded  
messages two hours in the  
event of a power failure or  
brownout. Allow 48 hours to  
fully charge.

period of time, turn the battery  
switch to the Off position to  
avoid permanent damage to  
the battery.  
NOTE: The suggested reliable  
lifetime of the rechargeable  
battery used in the equipment  
is 36 months. To ensure the  
system has reliable battery  
backup, it is recommended  
the battery be replaced every  
30 months.

Front Panel Operation  
The MDMU can record messages input from the front panel through the  
Hand Set, Tape, and Mic connectors. The unit also record and store  
messages input remotely through telephone access to the REM port using  
a DTMF (touch tone) telephone.
