AUDIO ENHANCEMENT MS-720 Network Interface for 2-Way Intercom User Guide

The MS-720 Network Interface for 2-Way Intercom is a fully integrated networked classroom amplifier and wireless microphone receiver, perfect for audio in small rooms. This amplifier has network-based intercom, paging and emergency notification. It is easy-to-use, easy to install, and features an intuitive user interface. The entire unit utilizes Power over Ethernet (PoE+) and supports full duplex SIP communications. When used in conjunction with an Uninterruptable Power Supply (UPS), paging can still be heard during power outages and emergencies. This unit can be installed as part of the EPIC (Education & Paging Intercom Communications) System®, SAFE (Signal Alert For Education) System®, or integrated with other building systems.

TROUBLESHOOTING

REBOOT
Press and hold the Reboot button for 5 seconds.
FACTORY RESET PROCEDURE
Press and hold the Factory Reset button until the Activity Indicator flashes green (10 seconds) and then release.
RESCUE MODE
Press and hold the Reboot button until the Activity Indicator illuminates red (15 seconds) and then release. Or disconnect PoE power, press and hold the Reboot button while applying PoE power.
SIP NOT CONNECTED
Verify that the SIP settings are correct on the device. Try pushing Settings from the Configure tab on
EPIC System again. Pushing Settings from the Devices List does not push SIP settings.
NO AUDIO
If there is no audio going through the speakers (bells, paging, intercom, teacher mic) check the audio output to see if there is any audio passing through there. This can be done by connecting a pair of wired headphones to the audio out of the MS-720 and playing audio through the MS-720. If you hear audio through the headphones, it is most likely not a problem with the MS-720, and related to the speakers or speaker wiring.
