CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN
REDUCE EYE, SHOULDER, AND NECK FATIGUE. CHECK THE
FOLLOWING WHEN YOU POSITION THE MONITOR:
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
•฀ For฀optimum฀performance฀of฀the฀monitor,฀allow฀20฀minutes฀for฀warming฀up.฀Avoid฀
reproduction of still patterns on the monitor for long periods of time to avoid image
persistence (after image effects).
•฀ Adjust฀the฀monitor฀height฀so฀that฀the฀top฀of฀the฀screen฀is฀at฀or฀slightly฀below฀eye฀level.฀
Your eyes should look slightly downward when viewing the middle of the screen.
•฀ Position฀your฀monitor฀no฀closer฀than฀40฀cm฀(15.75฀inches)฀and฀no฀further฀away฀than฀
70 cm (27.56 inches) from your eyes. The optimal distance is 50 cm (19.69 inches).
•฀ Rest฀your฀eyes฀periodically฀for฀5฀to฀10฀minutes฀for฀every฀1฀hour฀by฀focusing฀on฀an฀object฀
at least 20 feet away.
•฀ Position฀the฀monitor฀at฀a฀90°฀angle฀to฀windows฀and฀other฀light฀sources฀to฀minimize฀glare฀
and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen.
•฀ If฀reflected฀light฀makes฀it฀hard฀for฀you฀to฀see฀your฀screen,฀use฀an฀anti-glare฀filter.
•฀ Adjust฀the฀monitor’s฀brightness฀and฀contrast฀controls฀to฀enhance฀readability.
•฀ Use฀a฀document฀holder฀placed฀close฀to฀the฀screen.
•฀ Position฀whatever฀you฀are฀looking฀at฀most฀of฀the฀time฀(the฀screen฀or฀reference฀material)฀directly฀in฀front฀of฀you฀to฀minimize฀
turning your head while you are typing.
•฀ Blink฀often.฀Eye฀exercise฀helps฀to฀reduce฀eye฀strain.฀Please฀contact฀your฀ophthalmologist.฀Get฀regular฀eye฀checkups.
•฀ To฀avoid฀eye฀fatigue,฀adjust฀the฀brightness฀to฀a฀moderate฀setting.฀Place฀a฀sheet฀of฀white฀paper฀next฀to฀the฀LCD฀screen฀for฀
luminance reference.
•฀ Do฀not฀position฀the฀Contrast฀control฀to฀its฀maximum฀setting.
•฀ 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.
•฀ Suitable฀for฀entertainment฀purposes฀at฀controlled฀luminous฀environments,฀to฀avoid฀disturbing฀reflections฀from฀the฀screen.
Cleaning the LCD Panel
•฀ When฀the฀LCD฀is฀dusty,฀please฀gently฀wipe฀with฀a฀soft฀cloth.
•฀ Clean฀the฀LCD฀monitor฀surface฀with฀a฀lint-free,฀non-abrasive฀cloth.฀Avoid฀using฀any฀cleaning฀solution฀or฀glass฀cleaner!
•฀ Please฀do฀not฀rub฀the฀LCD฀panel฀with฀hard฀or฀coarse฀material.
•฀ Please฀do฀not฀apply฀pressure฀to฀the฀LCD฀surface.
•฀ Please฀do฀not฀use฀OA฀cleaner฀as฀it฀will฀cause฀deterioration฀or฀discoloration฀on฀the฀LCD฀panel฀surface.
Cleaning the Cabinet
•฀ Unplug฀the฀power฀supply
•฀ Gently฀wipe฀the฀cabinet฀with฀a฀soft฀cloth
•฀ To฀clean฀the฀cabinet,฀dampen฀the฀cloth฀with฀a฀neutral฀detergent฀and฀water,฀wipe฀the฀cabinet฀and฀follow฀with฀a฀dry฀cloth.
NOTE: DO NOT clean with benzene thinner, alkaline detergent, alcoholic system detergent, glass cleaner, wax, polish
cleaner, soap powder, or insecticide. Rubber or vinyl should not be in contact with the cabinet for an extended period
of time. These types of fluids and materials can cause the paint to deteriorate, crack or peel.
