Low Blue Light Filter and Eye Health

The Blue Light Filter blocks high-energy blue light for a more comfortable viewing experience.

Calculating Breaks

When viewing screens for extended periods, it is recommended to take periodic breaks from viewing. Short breaks of at least 10 minutes are recommended after one (1) hour of continuous viewing.

Taking shorter, more frequent breaks are generally more beneficial than longer, less frequent breaks.

Focus Fatigue (20-20-20 Rule)

To reduce the risk of eye fatigue by constantly looking at the screen, look away from the screen at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds.

Looking at Distant Objects

While taking breaks, users can further reduce eye strain and dryness by focusing on objects that are further away from them for 10-15 seconds, then gaze at something up close for 10-15 seconds. Repeat this up to 10 times. This exercise reduces the risk of your eyes’ focusing ability to “lock up” after prolonged computer work.

Eye and Neck Exercises

Eye Exercises

Eye exercises can help minimize eye strain. Slowly roll your eyes to the left, right, up, and down. Repeat as many times as needed.

Neck Exercises

Neck exercises can also help minimize eye strain. Relax your arms and let them hang at your sides, bend forward slightly to stretch the neck, turn your head to the right and to the left. Repeat as many times as needed.

Using the ViewBoard Safely

Please read the following Safety Precautions before you start using the device.

Keep this user guide in a safe place for later reference.
Read all warnings and follow all instructions.
Do not use the device near water. To reduce the risk of fire or electric shock, do not expose the device to moisture.
Never remove the rear cover. This display contains high-voltage parts. You may be seriously injured if you touch them.
Avoid exposing the device to direct sunlight or other sources of sustained heat.
Do not install near any heat sources such as radiators, heat registers, stoves, or other devices (including amplifiers) that may increase the temperature of the device to dangerous levels.
Use a soft, dry cloth to clean the external housing.
When moving the device, be careful not to drop or bump the device on anything.
Do not place the device on an uneven or unstable surface. The device may fall over resulting in an injury or a malfunction.
Do not place any heavy objects on the device or connection cables.
If smoke, an abnormal noise, or a strange odor is present, immediately turn the device off and call your dealer or ViewSonic®. It is dangerous to continue using the device.
The device is a monitor with an LED backlight intended for general office use.
Do not attempt to circumvent the safety provisions of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade and the third prong are provided for your safety. If the plug does not fit into your outlet, obtain an adapter and do not attempt to force the plug into the outlet.

When connecting to a power outlet, DO NOT remove the grounding prong. Please ensure grounding prongs are NEVER REMOVED.
Protect the power cord from being treaded upon or pinched, particularly at the plug, and at the point where it emerges from the equipment. Ensure that the power outlet is located near the equipment so that it is easily accessible.
Only use attachments/accessories specified by the manufacturer.
When a cart is used, use with caution when moving the cart/equipment combination to avoid injury from tipping over.
Disconnect the power plug from the AC outlet if the device is not being used for a long period of time.
Place the device in a well-ventilated area. Do not place anything on the device that prevents heat dissipation.

Refer all servicing to qualified service personnel. Service will be required when the unit has been damaged in any way, such as:
- if the power supply cord or plug is damaged
- if liquid is spilled onto or objects fall in the unit
- if the unit is exposed to moisture
- if the unit does not operate normally or has been dropped

CAUTION

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

When the power supply cord or plug is damaged.
If liquid has been spilled onto or objects have fallen into the unit.
If the unit has been exposed to moisture.
If the unit does not operate normally or has been dropped.

Never place the device in an unstable location. The device may fall, causing serious personal injury or death. Many injuries, particularly to children, can be avoided by taking simple precautions such as:

Using cabinets or stands recommended by the manufacturer of the device.
Only using furniture that can safely support the device.
Ensuring the device is not overhanging the edge of the supporting furniture.
Not placing the device on tall furniture (e.g., cupboards or bookcases) without anchoring both the furniture and the device to a suitable support.
Not placing the device on cloth or other materials that may be located between the device and supporting furniture.
Educating children about the dangers of climbing on furniture to reach the device or its controls.

If the existing device is going to be retained and relocated, the same considerations as above should be applied.

Do not use the system continuously for long periods of time.

Cleaning the Screen

Use a clean, soft, lint-free cloth and gently wipe down your screen to remove dust and other particles.
If the screen is still not clean, apply a small amount of non-ammonia, non-alcohol based glass cleaner onto a clean, soft, lint-free cloth; then wipe the screen.

Cleaning the Case

Use a clean, soft, lint-free cloth and gently wipe down the case to remove dust and other particles.
If the case is still not clean, apply a small amount of non-ammonia, non-alcohol based, mild non-abrasive detergent onto a clean, soft, lint-free cloth, then wipe the surface.

Disclaimer

ViewSonic® does not recommend the use of any ammonia or alcohol-based cleaners on the display screen or case. Some chemical cleaners have been reported to damage the screen and/or case of the device.
ViewSonic® will not be liable for damage resulting from use of any ammonia or alcohol-based cleaners.
