Troubleshooting
Checking the
suspicious settings
The following settings are suspected as the cause
of unintended Internet access. When you use a
new operating system first time, or when you have
installed new software, check the setting by using
the following example as a reference.
If outgoing calls are generated
frequently
Check the DNS setting value in the network setting
of the PC. If an IP address of a DNS server located
in the Internet is specified, Internet access may be
made frequently.
If outgoing calls are generated every
time the PC is started
If there is any software that is started at the same
time with the start of PC, depending on the setting,
Internet access may be made every time the PC
is started. Check the software setting, and if auto
update or other functions are enabled, change
the setting.
If outgoing calls are generated at
regular intervals
• If outgoing calls are generated many times a day:
Windows Update may be used or the automatic
e-mail transmission/reception may be enabled.
Check the relevant software setting of the PC
connected to the LAN of this product.
• If outgoing calls are generated several times
a day: Check the settings of the maintenance
program of the hardware or NTP server (Internet
automatic time server).
Homepage banner advertising
If the homepage includes a banner adverting, the
homepage may be updated automatically at regular
intervals although no operation is performed. If you
leave the Web browser with the page open, Internet
connection is made at regular intervals, incurring
fees each time. Close the Web browser each time,
to prevent unintended Internet access.
Subscription of contents
If Internet Explorer feeds and Web Slices are used,
Internet connection is made at specified intervals
to update the contents. You will be charged every
time the contents are updated. Therefore, when
you subscribe to any content, check the update
intervals carefully.
If you do not need such setting, cancel it.
