CAUTION
When shipped from the factory, the IP address of all VN-A1U units is set to
192.168.0.2 Consequently, if multiple units are installed in the same LAN
environment and the power is turned ON at the same time, duplication of IP
addresses will occur and correct access will not be possible. Always turn the
power on for only one unit at a time. Once duplication of IP addresses has occurred
(and after confirming that only one VN-A1U exists in the same LAN environment),
wait a while (10 minutes or longer), or turn off the power of all the network devices
on the same LAN environment, before turning the power ON again. If this is not
done, it may not be possible to access the VN-A1U.
