If this phenomenon occurs after connecting to the

network, there may be a loop between two Ethernet

switching hubs within the network, as explained below.

- There are two or more Ethernet switching hubs in a

network.

- Two of the hubs are doubly connected by LAN cables.

- This double connection forms a loop between the two

hubs.

Such a loop may have an adverse effect on the projector

as well as the other network devices.

Check the network connection and remove the loop by

disconnecting the LAN cables such that there is only one

connecting cable between two hubs.
