3 Plug the modular cord into connector J1 on MDMU and connect the wires on the other end to the Over Ride terminal. Figure 4. MDMU Connection to Over Ride 4 Connect the RJ-21 cable/connector to the MDMU Aux. Interface and to terminal block. NOTE: For specific pin-out information for this connector refer to Figure 9 at the end of this guide.
5 Set the MDMU options on the DIP switch. Refer to the table below. NOTE: Switches 1, 2, and 3 sets the number of messages in a single queue sequence. The timing between those messages is set by switches 4, 5, and 6. Switch 7 sets the total possible number of messages for the unit.
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.
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.
NOTE: Depending on number of messages optioned during installation (switch 7), the (available message numbers will read 1 through 9, or 01 through 99. To record on another message number, press the FUNC key until the desired message number appears.
Listening to Recorded Messages NOTE: Use the front panel handset to listen to messages. 1 2 3 4 Press the FUNC button until the display indicates monitor. MONITOR Press the RUN button to select the message number. MSG-01 Press the FUNC key until the desired message number appears.

Playing Messages in Sequence A group or sequence of messages can be played to the output channel. The maximum number of messages in a sequence can be up to 8 (determined by the DIP switch settings on the back panel). To add messages to the sequence simply repeat the PLAY command, selecting the message to be added each time.
Adding a Time Delay Between Message Plays A time delay can be inserted before successive message plays. The amount of time depends on the maximum time delay set on the option DIP switch. 1 2 3 4 5 6 7 NOTE: A delay may only be selected for a message which has previously been recorded.
Clearing a Message Sequence The message sequence can be cleared leaving the individual messages to be played separately. Press the FUNC button until PLAY is displayed PLAY Press the RUN button. MSG-01 1 2 3 4 Press the FUNC button until the following message is displayed.
Checking Message Times The TIME function displays the time used for each message recorded. It also displays the remaining time available in system memory to record other messages. Press the FUNC button until TIME appears. TIME Press the RUN button (once) to view message numbers and recording time.
Reset Delay Times to Default The INIT (initialize) function resets the operating parameters and delay time to the default setting of five seconds without effecting the recorded messages. Press the FUNC button until INIT appears. INIT Press the RUN button.
