Power Saving Function in the Sound Chip
The network connection may be severed when entering the ECO mode and suspend
(hibernation) mode. Be sure to disable the [Suspend/Hibernation Timeout] settings
with the Setup Utility if you require a network environment.
When the power saving function is running, communications software may malfunc-
tion. For example, communications may be halted if the suspend (hibernation) mode
is activated. The computer must be restarted if one of these modes is entered during
data communications.
Be sure that the computer enters the ECO mode or suspend (hibernation) mode
after the communications software is closed.

If any of these faults occurs, try using the software with some Internet Explorer 4.01
functions turned off. (See Internet Explorer Help for more details.)
