Repairs to this equipment, other than routine repairs, can be made only by the manufacturer or its authorized agents.

Notice

Every effort was made to ensure that the information in this guide was complete and accurate at the time of printing. However, information is subject to change.

FCC Statement (Part 15) - Radio Frequency

If the equipment causes harm to the telephone network, the local telephone company may temporarily discontinue your service and, if possible, notify you in advance. If advance notice is not practical, you will be notified as soon as possible. You will be given the opportunity to correct the problem and informed of your right to file a complaint with the FCC.

Interference

The Multiple Digital Message Unit generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. Testing is being conducted 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 interference by one or more of the following measures:

- 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.

If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The user may find the following booklet. "How To Identify and Resolve Radio-TV Interference Problems," helpful. This booklet was prepared by the Federal Coommunications Commission (FCC) and is available from the U.S. Government Printing Office, Washington, DC 20402. Stock order No. 004-00000345-4.

Federal Communications Commission (FCC) Statement (Part 68)

This equipment is component registered with the Federal Communications Commission (FCC) in accordance with Part 68 of its rules. In compliance with the rules, be advised of the following:

The local telephone company may make changes in its facilities, operations, or procedures that could affect the proper functioning of your equipment. If they do, you will be given adequate notice in writing to allow you an opportunity to maintain uninterrupted telephone service.

Important Safety Information

Always follow these basic safety precautions when installing and using the system:

1. Read and understand all instructions.

2. Follow all warnings and instructions marked on the products.

3. DO NOT block or cover the ventilation slots and openings. They prevent the product from overheating. DO NOT place the product in a separate enclosure or cabinet, unless proper ventilation is provided.

4. Never spill liquid on the product or drop objects into the ventilation slots and openings. Doing so may result in serious damage to the components.

5. Repair or service must be performed by a factory authorized repair facility.

6. The product is provided with a CSA approved, 3-wire ground type plug. This is a safety feature. DO NOT defeat the safety purpose of the grounding type plug. DO NOT staple or otherwise attach the AC power supply cord to building sur-

faces.

7. DO NOT use the product near water or in a wet or damp place (such as a wet basement).

8. DO NOT use extension cords. The product must be installed within 6 feet of a grounded outlet receptacle.

9. DO NOT install telephone wiring during a lightning storm.

10. DO NOT install telephone jacks in a wet location unless the jack is specifically designed for wet locations.

11. Never touch uninsulated wires or terminals, unless the line has been disconnected at the paging or controller interface.

12. Use caution when installing or modifying paging or control lines.

Registered eqipment may not be used with Coin Telephone Lines. Equipment may be used with Party Lines in areas where state tariffs permit such connections and when equipment is adaptable for such service.

This equipment is registered as follows: Registration Number - F4PCAN-20988-AN-N Ringer Equivalence -1.6B

If trouble is experienced, the equipment should be disconnected from the interface to determine if this equipment, or the telephone line is the trouble source. If the equipment is determined to be malfunctioning, it should not be reconnected until repairs are effected.

Support Information

Paging systems integrated with small phone systems such as Merlin Legend and Partner are supported by the National Service Assistance Center (NSAC). The main number for the NSAC is 800-628-2888. Paging systems integrated with large switches such as the DEFINITY G3 are supported by the Technical Service Center (TSC). The main number for the TSC is 800-242-2121.

Introduction

Before You Start

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 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.

Power Up System

Plug the power cord into the A.C. input connector on the MDMU, then into the wall oulet.

The MDMU will display three messages in sequence:

MDMU 2.00

Software version of unit.

3.16

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.

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.

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.

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.

Push the Battery slide switch to the ON position.

The MDMU is now ready to record and play meassages.
