whether your network supports the above network speeds and set it accordingly. If the network conguration does not match any
of these values, it is recommended to use Auto Negotiation (the Auto option) or refer to your network equipment manufacturer.
Press the center button to continue to the next CMC Network Settings screen.
5 Select the duplex mode (half or full) that matches the network environment.
NOTE: The network speed and duplex mode settings are not available if Auto Negotiation is set to On or 1000MB (1Gbps)
is selected.
If auto negotiation is turned on for one device but not the other, then the device using auto negotiation can determine the network
speed of the other device, but not the duplex mode; in this case, duplex mode defaults to the half duplex setting during auto
negotiation. Such a duplex mismatch results in a slow network connection.

press the center key to return to the screen for that setting. After making a correction, press the center
button.
• When you have conrmed the accuracy of the settings you entered, press the center button. The
