Sony PCV-RX780 Manual

❑

Disconnect the system from its power source and from any 
telecommunications links, networks, or modems before you open the system 
or follow any of the procedures described in the online manual, Upgrading 
and Maintaining Your VAIO Digital Studio Computer. Failure to do so may 
result in personal injury or equipment damage.

❑

Electrostatic discharge (ESD) can damage disk drives, add-on cards, and 
other components. Follow the procedures described in the online manual, 
Upgrading and Maintaining Your VAIO Digital Studio Computer, only at an 
ESD workstation. If such a station is not available, do not work in a carpeted 
area, and do not handle materials that produce or hold static electricity (for 
example, cellophane wrappers). Ground yourself by maintaining continuous 
contact with an unpainted metal portion of the chassis while performing the 
procedure.

❑

When removing a slot cover, be careful not to damage components on the 
system board or add-on cards. You may need to temporarily remove add-on 
cards that are next to the slot cover you want to remove.

❑

Do not change the CRT display refresh rate to 85 Hz, as DVD playback and 
the DVgate software may not function correctly. Sony recommends that you 
keep your CRT display at the preset, optimal refresh rate (75 Hz).

❑

Do not place the display near a strong magnetic force.

❑

Do not block the ventilation slots on the display.

❑

Using the computer in low temperature conditions may produce a residual 
image on the screen. This is not a malfunction. When the computer returns to 
normal temperature, the screen returns to normal.

❑

A residual image may appear on the screen if the same image is displayed 
for a lengthy period of time. The image disappears after a period of time. 
You can use a screen saver to prevent residual images.

❑

The screen becomes warm during operation. This is normal and does not 
indicate a malfunction.
