Protecting your nScreen from viruses and other security threats

Your nScreen may come pre-installed with an anti-virus
software, which can help you avoid unexpected destruction of
your precious data in the nScreen and keeps your privacy
against any unauthorized access from other computers.

The anti-virus software protects your computer against Internet
threats, such as viruses, Spyware, hackers, and spam. In
addition, you can secure your personal information, block
unwanted web sites, and check e-mail for viruses.

However, we would still recommend that you back up your data
regularly on CDs, DVDs, or other external storage device, since
the anti-virus software may not be able to intercept all existing
and new viruses, which may lead to destruction of all or some of
your data in the nScreen.

For more information about how to use the anti-virus software
installed, refer to the online help that comes with the software.

Furthermore, it is also recommended to set Windows to
automatically install important updates for your nScreen.
Important updates can bring you significant benefits, such as
improved security and reliability.

For more information about how to use Windows Update, refer
to Start > Help and Support in Windows XP.

Why is the hard disk capacity displayed by the OS different from
its nominated capacity?

You may have discovered that the capacity of a 10GB hard disk
becomes 9GB when displayed from the OS, and 20GB becomes
19GB, etc. The bigger the capacity, the bigger the difference. It is
because hard disk manufacturers and OS developers calculate

hard disk capacity in different ways. As a result, the nominated
capacity is different from the exact capacity displayed by the OS.

• Connect the earphone to other devices, such as a radio to see if
you can still hear that noise. If the noise persists, the earphone
may be out of order.

• If you can hear the noise only when inserting, it is the result of
high instantaneous current. It is a normal phenomenon.

Exact capacity of a 40GB hard disk displayed in the OS:

40,000,000,000÷1024÷1024÷1024=37.2529 (GB).

Furthermore, when a hard disk is partitioned, the system will
reserve some space on the drive for system files. Therefore, the
total capacity of a hard disk displayed by the OS will never be
the same as its nominated capacity.

Why is my nScreen running so hot? Is it normal?

Yes. Because all the hardware is in such cramped quarters, it
tends to get hot. To prevent overheating, do not obstruct the
vent. For example, do not use the nScreen in bed where a
blanket may inadvertently cover the vent and block the airflow.

Why does my nScreen seem to turn off itself after a certain
period of inactivity?

This is the default setting of the nScreen to conserve power. The
nScreen is configured to use the power saving feature. You can
go to

Start > Control Panel > Performance and

Maintenance

> Power Options in Windows to adjust the

setting manually.
