• Use the supplied power cord.

If you use the display in UK, please use the supplied UK cable with UK plug.

• Before disconnecting the power cord, wait at least 30 seconds after turning

off the power switch to discharge static electricity from the CRT display
surface.

• After the power has been turned on, the CRT is demagnetized for

approximately 5 seconds. This generates a strong magnetic field around the
bezel which may affect the data stored on magnetic tape or disks near the
bezel. Place such magnetic recording equipment and tapes/disks at a distance
from this unit.

The socket-outlet shall be installed near the equipment and shall be easily
accessible.

When using a video mode that is not one of the 10 factory preset modes, some
fine tuning may be required to optimize the display to your preferences. Simply
adjust the display according to the adjustment instructions. The adjustments will
be stored automatically and recalled whenever that mode is used.
A total of 10 user-defined modes can be stored in memory. If an 11th mode is
entered, it will replace the first.

With the tilt-swivel, this unit can be adjusted to be viewed at your desired angle
within 90° horizontally and 7° vertically.
To turn the unit vertically and horizontally, hold it at its bottom with both hands.
Pay attention not to get your hands caught between the display and the tilt-
swivel.

Using a white background, very thin horizontal lines on the screen are visible as
shown below. These lines are the damper wires.
The Trinitron tube has a vertically striped Aperture Grille inside. The Aperture
Grille allows more light to pass through to the screen giving the Trinitron CRT
more color and brightness.
The damper wires are attached to the Aperture Grille to prevent vibration of the
Aperture Grille wire so that the screen image is constantly stable.
