Action
If the refresh rate is not optimal for the connected
CRT, then this problem may occur.
To correct this problem do the following:
1. Right-click touchpad or mouse button.
2. Select Graphics Options > Graphics Settings,
the Intel Graphics Controller page opens.
3. Click the Monitor tab
4. Adjust the Refresh rate to other selections until
you see the CRT clearly.
Action
If your modem has difficulty in connecting to on-
line services and sustaining communications, first
check if other devices are connected and remove
them. Also remove any extension leads. Interference
from certain devices or poor line power conditions
may degrade the quality of your connection. Under
these conditions gradually reduce the
communication speed of your modem until a reliable
connection is achieved.
Check with your on-line service provider.
If you use a PBX phone system you may need to
press a number i.e. '9' to connect to an external line,
you should enter the following command before
trying the connection and check modem
initialization.
(ATX3&W)
And add "9," as the external line prefix (example) of
the phone number when using the dial command
"ATDT9, 123-4567"
