•
Is the same IP address provided to other devices?
Are there contradictions between the address and the
network subnet to be accessed?
When the microphone and the PC are connected in
the same subnet:
Are the IP addresses of the microphone and the PC set
in a common subnet? Or is "Use Proxy Server" for the
settings of the web browser checked?
When accessing the microphone in the same subnet, it
is recommended to enter the address of the microphone
in the "Don't Use Proxy For These Addresses" box.
When the microphone and the PC are connected in
the different subnet:
Is the IP address of the default gateway set for the
microphone correct?
•
Did you access "http://" while using the HTTPS
function?
To use the HTTPS function, access "https://". It is also
necessary to enter the port number.
•
Are the network settings of the microphone correct?
Set the default gateway or DNS server address
correctly. To use the DDNS service, check that the
settings are correct.
•
Is the setting for "Default gateway" on the "Network"
page configured? Or is the setting correct?
When communicating using IPv4:
Configure the setting for "Default gateway" of "IPv4
network" on the [Network] tab of the setup menu.
•
Is the setting of port forwarding configured for the
router?
To enable the access to the microphone via the
Internet, it is necessary to perform the port forwarding
setting when the router in use does not support the
UPnP function. Refer to the manuals provided with the

•
Is the UPnP function of the router disabled?
Refer to the manuals provided with the router in use to
