Safety Precautions
Should any liquid or solid object fall into the cabinet, unplug the unit and have it checked
by qualified personnel before operating it any further.
Unplug the unit from the wall outlet if it is not going to be used for several days or more.
To disconnect the cord, pull it out by the plug. Never pull the cord itself.
Allow adequate air circulation to prevent internal heat build-up. Do not place the unit on
soft surfaces (rugs, carpets, sofas, etc.) or near materials (curtains, draperies) that may block
the ventilation holes.
Height and vertical linearity controls located on the rear panel are for special adjustments
by qualified personnel only.

IMPORTANT SAFEGUARDS
1. READ INSTRUCTIONS – Read the safety and operating instructions before
operating the monitor.
2. RETAIN INSTRUCTIONS – Retain the safety and operating instructions for future
reference.
3. CLEANING – Unplug video monitor from the wall outlet before cleaning. Do not use
liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.
4. ATTACHMENTS – Do not use attachments not approved by the video monitor
manufacturer as they may result in the risk of fire, electric shock or injury.
5. WATER AND MOISTURE – Do not use video monitor near water; for example, near
a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool.
6. ACCESSORIES – Do not place video monitor or equipment on an unstable cart, stand
or table. The video monitor or equipment may fall, causing serious injury and serious
damage to the equipment. Wall or shelf mounting should follow the manufacturer’s
instructions, and should use a mounting kit approved by the manufacturer.
7. CARTS – Video monitor and cart combinations should be moved with
care. Quick stops, excessive force and uneven surfaces may cause the
equipment and cart combination to overturn.
8. VENTILATION – Slots and openings in the cabinet and the back or bottom are
provided for ventilation, to ensure reliable operation of the video monitor and to protect it
from overheating. These openings must not be blocked or covered. The openings should
never be blocked by placing the video monitor on a bed, sofa, rug or other similar surface.
Video monitor should never be placed near or over a radiator or heat register. Video
monitor should not be placed in a built-in installation such as a bookcase unless proper
ventilation is provided.
9. POWER SOURCES – Video monitor should be operated only from the type of power
source indicated on the marking label. If you are not certain of the type of power supply you
have, consult your video monitor dealer or local power company.
10. GROUNDING OR POLARIZATION – This video monitor may be equipped with
a polarized alternating-current line plug (a plug with one blade wider than the other). This
plug will fit into the power outlet only one way. This is a safety feature. If you are unable
to insert the plug fully into the outlet, try reversing the plug. If the plug still fails to fit, contact
your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
polarized plug. If your video monitor is equipped with a three-wire grounding-type plug (a
plug having a third grounding pin), this plug will only fit into a grounding-type power outlet.
This is a safety feature. If you are unable to insert the plug into the outlet, contact your
electrician to replace your obsolete outlet. Do not defeat the safety purpose of the
grounding-type plug.

11. POWER CORDS – Do not allow anything to rest on the power cord. Do not locate
video monitor or equipment where the cord can be damaged by persons walking on it.
12. HEED WARNINGS – Follow all instructions marked on the video monitor.
13. LIGHTNING – During lightning storms or when the monitor will be left unattended
and unused for long periods, unplug the monitor and associated equipment from the wall
outlet. This will prevent damage to the video equipment caused by lightning and power-line
surges.
14. OVERLOADING – Do not overload wall outlets and extension cords as this can result
in a risk of fire or electric shock.
15. OBJECT AND LIQUID ENTRY – Never push objects of any kind into video
monitor through openings as they may touch dangerous voltage points or short out parts
that could result in a fire or electric shock. Never spill liquid of any kind on the product.
16. SERVICING – Do not attempt to service video monitor as opening or removing
covers may expose you to dangerous voltage or other hazards. Refer all servicing to
qualified service personnel.
17. DAMAGE REQUIRING SERVICE – Unplug video monitor and equipment from
the wall outlet and refer servicing to qualified service personnel under the following
conditions:
A. When the power-supply cord or the plug has been damaged.
B. If liquid has spilled, or objects have fallen into the monitor.
C. If the monitor has been exposed to rain or water.
D. If the monitor does not operate normally when following the operating instructions,
adjust only those controls that are covered by the operating instructions as an improper
adjustment of other controls may result in damage and will often require extensive work
by a qualified technician to restore the monitor to its normal operation.
E. If the monitor has been dropped or the cabinet damaged.
F. When the monitor exhibits a distinct change in performance, this indicates a need for
service.
18. REPLACEMENT PARTS – When replacement parts are required, be sure the
service technician uses replacement parts specified by the manufacturer or that have the
same characteristics as the original part. Unauthorized substitutions may result in fire,
electric shock or other hazards.
19. SAFETY CHECK – Upon completion of any service or repairs to the monitor, ask the
service technician to perform safety checks to determine that the video product is in proper
operating condition.
20. FIELD INSTALLATION – Installation should be performed by a qualified service
person and should conform to all local codes.
