If optional equipment is to be installed, leave some space 

between optional equipment and the display set. Picture 

distortion and/or noisy sound may occur if the display set 

is positioned in close proximity to any equipment emitting 

electromagnetic radiation.

Keep small accessories in a safe place where children are 

unable to reach.

This display contains a strong magnet in the speaker 

unit that generates a magnetic field. Keep any items 

susceptible to magnetic fields away from the speaker.

If you hear snapping or popping sound 

comes from the display continuously or 

frequently while the display is operating, 

unplug the display and consult your dealer 

or service technician. It is normal for some 

displays to make occasional snapping or 

popping sounds, particularly when being 

turned on or off.

This display is not designed for outdoors 

installation. Do not expose the display to 

rain, as it may result in a fire or an electric 

shock. Also, do not expose the display 

to direct sunlight, as it may heat up and 

become damaged.

Do not install this display in a vehicle.

Car accidents may cause the display to fall 

down and cause injury.

Do not install this display in a ship or vessel.

If the display is exposed to seawater, it may 

cause a fire or damage the display.

Do not place this display in a place where medical 

equipment is in use. It may cause the medical equipment 

to malfunction.

•  Adjust the volume to avoid disturbing your neighbors. 

Sound carries easily at night. Therefore, we suggest 

you close the windows or use headphones.

•  When using headphones, adjust the volume to 

appropriate levels, or hearing damage may result.

If an outdoor antenna is installed, follow the precautions 

below. Do not install the outdoor antenna system near 

of overhead power lines or other electric light or power 

circuits, or where it can come in contact with such power 

lines or circuits.

WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, 

EXTREME CARE SHOULD BE TAKEN TO KEEP FROM 

CONTACTING SUCH POWER LINES OR CIRCUITS AS 

CONTACT WITH THEM IS ALMOST INVARIABLY FATAL.

Be sure the antenna system is grounded so that it can 

provide some protection against voltage surges and built-

up static charges.

Section 810 of the National Electrical Code (NEC) in the 

U.S.A. and Section 54 of the Canadian Electrical Code 

in Canada provides information with in regard to proper 

grounding of the mast and supporting structure, grounding 

of the lead-in wire to an antenna discharge unit, size of 

grounding conductors, location of antenna discharge unit, 

connection to grounding electrodes, and requirements for 

the grounding electrode.

Unplug the AC power plug and clean it 

regularly. If the plug is covered with dust 

and gathers moisture, its insulation may 

deteriorate and result in a fire.

When cleaning this display, unplug the AC 

power cord. If not, it may result in electric 

shock. Use a dry soft cloth to clean the 

cabinet of the display. To remove dust 

near the screen, wipe it gently with a soft 

cloth.

Stubborn stains may be removed with a cloth slightly 

dampened with a solution of mild soap and warm water. 

Never use strong solvents such as thinner or benzine for 

cleaning. If using a chemically pretreated cloth, please 

follow the instruction provided on the package. The 

ventilation holes can accumulate dust over time.

To ensure proper ventilation, we recommend you to 

remove the dust periodically (once a month) using a 

vacuum cleaner, while the display is powered off.

Some chemical cleaners have been reported to damage 

the screen and/or case of the display. ViewSonic will not 

be liable for damage resulting from use of these cleaners.

To prevent dropping the display and causing serious 

injury, you must follow these guidelines:

•  Disconnect all cables before carrying the display.

•  Carrying the large size display requires at least two or 

three people.

•  When you carry the display, place your hands as 

illustrated and hold it securely. Do not put stress on the 

panel and the frame around the screen.

•  When carrying the display, do not subject it to shocks, 

vibration, or excessive force.
