Safety Precautions and Maintenance

FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE

FOLLOWING WHEN SETTING UP AND USING

THE MITSUBISHI COLOR MONITOR:

• DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and opening or

removing covers may expose you to dangerous shock hazards or other risks. Refer all servicing to
qualified service personnel.

• Do not spill any liquids into the cabinet or use your monitor near water.

• Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage

points, which can be harmful or fatal or may cause electric shock, fire or equipment failure.

• Do not place any heavy objects on the power cord. Damage to the cord may cause shock or fire.

• Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall,

causing serious damage to the monitor.

•

Keep the monitor away from high capacity transformers, electric motors and other devices such as
external speakers or fans, which may create strong magnetic fields.

• If possible, position the monitor so that it is facing the east to minimize the effects of the earth’s

magnetic field.

• Changing the direction of the monitor while it is powered on may cause image discoloration. To

correct this, turn the monitor off for 20 minutes before powering it back on.

• When operating the monitor with its AC 220-240V worldwide power supply, use a power supply

cord that matches the power supply voltage of the AC power outlet being used. The power supply
cord you use must have been approved by and comply with the safety standards of your country.
(Type H05VV-F should be used except in UK)

• In UK, use a BS-approved power cord with molded plug having a black (5A) fuse installed for use with

this monitor. If a power cord is not supplied with this monitor, please contact your supplier.

Cleaning Your Monitor

A special coating is provided on the glass (CRT) surface of this monitor to reduce a reflection and
static electricity on the glass surface. Due to the delicate coating on the glass surface, use a lint-free,
non-abrasive cloth (cotton or equivalent) and a non-alcohol, neutral, non-abrasive cleaning solution
to minimize dust. If the screen requires more than a light cleaning, apply a soft neutral detergent and
water directly to a soft cloth and use it upon wringing water, to clean the glass surface. Clean your
monitor regularly.

CAUTION:

Benzene, thinner, acid/alkaline detergent, alcohol detergent, detergent with abrasive powder,
detergent with anti-static agent, detergent for cleaning.

Immediately unplug your monitor from the wall outlet and refer servicing to qualified service personnel
under the following conditions:

• When the power supply cord or plug is damaged.

• If liquid has been spilled, or objects have fallen into the monitor.

• If the monitor has been exposed to rain or water.

• If the monitor has been dropped or the cabinet damaged.

• If the monitor does not operate normally by following operating instructions.

CAUTION

The following agents will cause damage to the CRT when cleaning the glass surface:

• Allow adequate ventilation around the monitor so that heat can properly

dissipate. Do not block ventilated openings or place the monitor near a
radiator or other heat sources. Do not put anything on top of monitor.

• The power cable connector is the primary means of detaching the system

from the power supply. The monitor should be installed close to a power
outlet which is easily accessible.

• Handle with care when transporting. Save packaging for transporting.

CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR

CAN REDUCE EYE, SHOULDER AND NECK FATIGUE. CHECK THE

FOLLOWING WHEN YOU POSITION THE MONITOR:

• Adjust the monitor height so that the top of

the screen is at or slightly below eye level.
Your eyes should look slightly downward
when viewing the middle of the screen.

• Position your monitor no closer than 16 inches

and no further away than 24 inches from your
eyes. The optimal distance is 20 inches.

• Rest your eyes periodically by focusing on

an object at least 20 feet away. Blink often.

• Position the monitor at a 90° angle to

windows and other light sources to minimize
glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect
on your screen.

• If reflected light makes it hard for you to see your screen, use an anti-glare filter.

• Adjust the monitor’s brightness and contrast controls to enhance readability.

• Use a document holder placed close to the screen.

• Position whatever you are looking at most of the time (the screen or

reference material) directly in front of you to minimize turning your head
while you are typing.

• Get regular eye checkups.

Ergonomics

To realize the maximum ergonomics benefits, we recommend the following:

• Adjust the Brightness until the background raster disappears

• Do not position the Contrast control to its maximum setting

• Use the preset Size and Position controls with standard signals

• Use the preset Color Setting and Sides Left/Right controls

• Use non-interlaced signals with a vertical refresh rate over 75-160 Hz

• Do not use primary color blue on a dark background, as it is difficult to see

and may produce eye fatigue due to insufficient contrast
