FCC Statement (Part 15) - Radio Frequency
Interference
The Multiple Digital Message Unit generates and uses radio
frequency energy and if not installed and used in strict accor-
dance with the manufacturer's instructions, may cause interfer-
ence to radio and television reception. Testing is being con-
ducted for compliance with the limits for a Class B device in
accordance with the specifications in Part 15 of the FCC Rules
and Canadian D.O.C. regulations. This testing is designed to
provide reasonable protection against such interference.
However, there is no quarantees that interference will not
occur in a particular installation. If this equipment does cause
interference to radio or television reception, which can be
determined by turning the Multiple Digital Message Unit off
and on, the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
The local telephone company may make changes in its facilities,
operations, or procedures that could affect the proper func-
tioning of your equipment. If they do, you will be given ade-
quate notice in writing to allow you an opportunity to main-
tain uninterrupted telephone service.
Important Safety Information
Always follow these basic safety precautions when installing
and using the system:
- Reorient the radio or TV receiving antenna.
- Relocate the Multiple Digital Message Unit with respect to
the radio or TV receiver or vice-versa.
- Plug the Multiple Digital Message Unit unit into a different
outlet so that it and the radio or TV receiver are on different
branch circuits.

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.
Before You Start
Before installing your system, read and understand the safety instructions
on page ii. Be sure you have all the necessary parts, tools, and test
equipment, listed below.

Total time available in memory for
recording.
IDLE
Indicates the status MDMU: Idle = no
activity; PLY = A message is being
played out through connector J1; Delay =
the time delay between successive
messages is active.
Push the Battery slide switch to the ON position.

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.
The MDMU is now ready to record and play meassages.
If power is to be removed from
the MDMU for an extended
period of time, turn the battery
switch to the Off position to
avoid permanent damage to
the battery.
