Low Blue Light Filter and Eye Health

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.

Flicker-Free The CDE30 series uses DC-adjustable backlighting, which does not produce a visible or invisible flicker within the 0~3000 Hz range and therefore can reduce eye fatigue.

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.

IMPORTANT

To ensure the optimal performance and longevity of your display, it is essential to follow the recommended handling, mounting, and storage procedures. Placing the display in a horizontal position can lead to a range of potential issues, including:

Excessive stress on the display's structural components, resulting in the formation of cracks or distortions along the edges.
Uneven weight distribution, which can cause the screen to warp, sustain internal damage, or crack over time.
Thermal-related damage, as the internal components may not be able to dissipate heat as intended, leading to potential failure or permanent damage.

Furthermore, altering the display's form can also compromise the integrity of its internal components, including the sensitive LCD cells, which can result in a permanent degradation of the display's quality.

To prevent such issues and maintain the display's optimal condition, it is recommended to always mount, handle, transport, and store it in a vertical position. Failure to do so may void the warranty and compromise the display's performance and lifespan.

Note: Any damage resulting from the misuse or improper handling of the display is not covered under warranty.

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.
