AboutThisManual

VR320 Color Video Monitor

The VR320 is a color video monitor with a direct-view antiglare screen
and an auto-ranging power supply for worldwide operation. Its built-in
tilt-swivel stand lets you adjust the screen for your viewing comfort.
When connected to a host system, the VR320 can display information sent
by the host system.

Before You Start

This guide describes how to install, operate, and maintain your VR320
color monitor. You do not have to know a lot about computers to install
the VR320 monitor. Follow the steps in sequential order. No tools are
needed.

The kind of host system you have affects the way you prepare to operate
your monitor. Check the host system documentation to see if you need a
color video option installed in your host system to support the VR320
color monitor.

Check the host system package for the following:

• Video cable

• Keyboard

• Mouse (if ordered)

• Power cord
