Important Precautions

This unit has been engineered and manufactured to assure your
personal safety, but improper use can result in potential electrical
shock or fire hazard. In order not to defeat the safeguards
incorporated in this monitor, observe the following basic rules for its
installation, use, and servicing. Also follow all warnings and
instructions marked directly on your monitor.

On safety

1. Use only the power cord supplied with the unit. In case you use
another power cord, make sure that it is certified by the applicable
national standards if not being provided by the supplier.

2. If the power cable is faulty in any way, please contact the
manufacturer or the nearest authorized repair service provider for a
replacement.

3. Operate the monitor only from a power source indicated in the
specifications of this manual or listed on the monitor. If you are not
sure what type of power supply you have in your home, consult
with your dealer.

4. Overloaded AC outlets and extension cords are dangerous. So are
frayed power cords and broken plugs. They may result in a shock
or fire hazard. Call your service technician for replacement.

5. DO NOT OPEN THE MONITOR. There are no user serviceable
components inside. There are Dangerous High Voltages inside,
even when the power is OFF. Contact your dealer if the monitor is
not operating properly.

6. To avoid personal injury :

Do not place the monitor on a sloping shelf unless properly
secured.
Use only a stand recommended by the manufacturer.
Do not try to roll a stand with small casters across thresholds or
deep pile carpets.

7. To prevent Fire or Hazards:

Always turn the monitor OFF if you leave the room for more than
a short period of time. Never leave the monitor ON when leaving
the house.

A3

Important Precautions

Keep children from dropping or pushing objects into the monitor's
cabinet openings. Some internal parts carry hazardous voltages.
Do not add accessories that have not been designed for this
monitor.
During a lightning storm or when the monitor is to be left
unattended for an extended period of time, unplug it from the wall
outlet.
Do not bring magnetic devices such as magnets or motors near
the picture tube.

On installation

1. Do not allow anything to rest upon or roll over the power cord, and
do not place the monitor where the power cord is subject to damage.

2. Do not use this monitor near water such as near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet basement, or near a
swimming pool.

3. Monitors are provided with ventilation openings in the cabinet to
allow the release of heat generated during operation. If these
openings are blocked, built-up heat can cause failures which may
result in a fire hazard. Therefore, NEVER:

Block the bottom ventilation slots by placing the monitor on a
bed, sofa, rug, etc.
Place the monitor in a built-in enclosure unless proper ventilation
is provided.
Cover the openings with cloth or other material.
Place the monitor near or over a radiator or heat source.

On cleaning

Unplug the monitor before cleaning the face of the picture tube.
Use a slightly damp (not wet) cloth. Do not use an aerosol
directly

on the picture tube because overspray may cause

electrical shock

.

On repacking

Do not throw away the carton and packing materials. They make
an ideal container in which to transport the unit. When shipping
the unit to another location, repack it in its original material.
