The power cable connector is the primary means of

detaching the system from the power supply. The monitor

should be installed close to a power outlet, which is easily

accessible.

Handle with care when transporting. Save packaging for

transporting.

Please clean the holes of back cabinet to reject dirt and

dust at least once a year because of set reliability.

If using the cooling fan continuously, it’s recommended to

wipe holes a minimum of once a month.

When installing the remote control batteries;

-

Align the batteries according to the (+) and (-) indications

inside the case.

-

Align the (-) indication of the battery first inside the case.

CAUTION

Immediately unplug your monitor from the wall outlet and refer

servicing to qualified service personnel under the following

conditions:

When the power supply cord or plug is damaged.

If liquid has been spilled, or objects have fallen into the

monitor.

CAUTION

For optimum performance, allow 20 minutes for warm-up.

Rest your eyes periodically by focusing on an object at

least 5 feet away. Blink often.

Position the monitor at a 90

°

light sources to minimize glare and reflections.

Clean the LCD monitor surface with a lint-free, non-

abrasive cloth. Avoid using any cleaning solution or glass

cleaner!

Adjust the monitor’s brightness, contrast and sharpness

controls to enhance readability.

Avoid displaying fixed patterns on the monitor for long

periods of time to avoid image persistence (after image

effects).

Get regular eye checkups.

Ergonomics

To realize the maximum ergonomic benefits, we recommend

the following:

Use the preset Size and Position controls with standard

signals.

Use the preset Color Setting.

Use non-interlaced signals.

Do not use primary color blue on a dark background, as it

is difficult to see and may produce eye fatigue due to

insufficient contrast.
