doing so, click the ‘Save Settings’ button, wait 10 seconds and re-attach the Room Alert 4E unit to

Device Not Found Or Invalid IP Address
If the Room Alert 4E is not discovered by the AVTECH Device Discovery Utility, the network
may be blocking UDP broadcast packets on port 30718. Even if the Room Alert 4E obtains a valid IP
address, this can prevent the Room Alert 4E unit from being discovered. To resolve this issue, check the
DHCP server for the MAC address listed on the label located on the bottom of the Room Alert 4E unit.
If this is not possible or if there is not an entry in the DHCP server, follow the instructions listed under
the ‘Static-Only Networks’ subsection above.
If the Room Alert 4E unit is discovered although has a ‘169.xxx.xxx.xxx’ IP address, the Room Alert 4E
unit may not have been connected properly or DHCP assignment may currently be getting blocked. In either
case, follow the instructions listed in the ‘Static-Only Networks’ subsection above.
NOTE: If the instructions provided do not allow confi guration of the Room Alert 4E unit, please initiate a Live Chat technical
support request on AVTECH.com or send an email support request to [email protected].
