About This Guide
Overview
The PCXBV-Px Monitor is a 14-inch multi-scanning color monitor
with high resolution, compatible with VGA, SVGA 72 Hz and 75 Hz
modes.

The PCXBV-Px offers the following features:
768 vertical non-interlaced resolution

•

1024 horizontal

•

Power management system that exceeds the EPA Energy Star
requirements for saving energy

•

Complies with Swedish MPR2 standards for low magnetic
emissions

•

Anti-glare screen with anti-static coating

•

Tilt-swivel base

This product has been designed and manufactured to minimize
the impact to the environment. The monitor also has a power
management feature, which a personal computer can control to reduce
the monitor’s output power levels while not in use, thus saving energy.

Audience
This guide is intended for users who wish to install the monitor.

Conventions
The following conventions are used in this document:

Caution

Proper Setup and Use—Important Information
Certain recent scientific literature suggests that poor posture, work
habits, or office equipment setup may cause injuries. Other literature
suggests that there is no cause and effect. Because the safety of
our users is a great concern, it is important to take the precautions
described in Table 1.
If you experience pain or discomfort while using the monitor, take a
substantial break and review the instructions for posture and work
habits. If your pain or discomfort continues when you resume using
the monitor, discontinue use and report the condition to your job
supervisor or physician.

Adjust

To . . .

Keep your upper arms straight down at your sides, elbows
close to your sides to support your arm weight. Forearms
should be at a 70° to 90° angle.

Head

Avoid neck strain. Your head should incline downward, but
no more than 15° to 20°.

Monitor

Keep eye level and the correct distance for proper vision.

Eyes

Avoid eye fatigue, which can be caused by glare, image
quality, uncomfortable furniture, eye height, and
uncorrected vision. If you cannot read the screen at
different distances, you may need special glasses. Relax
your eyes periodically by looking at distant objects.

Work
Breaks

Take periodic work breaks. Morning, lunch, and afternoon
breaks meet most recommendations. Take advantage of
work breaks to move around and do other movements.

Lighting

Avoid direct lighting or sunlight on the screen, which
causes glare and reflections. The monitor screen has an
antiglare treatment to reduce glare. Place lighting behind
or to the side of your work area, and distribute the lighting
evenly on your work area. Adjust the monitor brightness
and the contrast controls as needed.

Noise

Keep background noise at a minimum. Background noise
above 65 dBA is tiring. Sound-absorbing materials, such
as curtains, carpeting, and acoustic tile, can help reduce
background noise.

Temperature

20°C to 23°C (68°F to 74°F)

Humidity

30% to 70%

Ventilation

Provide adequate air ventilation for equipment operation
and to avoid fatigue.

More than 70 cm (28 in) center to center, preferably more
than 152 cm (60 in).
