Note about BNC cables:
The BNC cables are better quality than regular cables and because they are co-ax and
shielded, they have better signal /noise ratio and are designed to protect the video signals
better in comparison with a regular cables. These cables normally are used in High end
monitors and you may have not seen them for smaller 14-17" monitors.

3 The degauss button manually demagnetizes the monitor. Degaussing disperses any
accumulated magnetic charge from the face of the monitor. Magnetic disturbances such as
picture distortion or color impurity can be caused by either moving the monitor from one
location to another or swiveling the monitor on its base. It is normal for the tube to shake
during degauss mode.

case the power light switches to orange. Please remember that there is another switch on the
back next to the AC power input and that switch must be in 1 position before the front power
switch can work.
