1. Precaution
Always use set voltage.
AC 100 ~ 230V, 50/60Hz
DC 24V(OBM-U178K, OBM-U248K, OBM-U278K, OBM-U318K)
All these instrucons should be read and understood before operang the unit.
If liquid is spilled on or impacts this product, please disconnect the product immediately
and seek professional help before connued use.
Unplug the product from the wall outlet if it is not to be used for several days or more.
Keep the product in a well-venlated place to prevent overheang.
Do not install the product near any heat-generang equipment. Also, keep the product out of direct sunlight
or dusty areas.
Protect the power cord from being walked on or pinched parcularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
When using other DC 24V(OBM-U178K, OBM-U248K, OBM-U278K, OBM-U318K) adapters instead of the
standard adapter provided by the manufacturer, please check the proper load capacity or current capacity
and use an adapter with stable voltage.
Do not overload AC outlets or extension cords. Overloading can cause fire or electric shock.
A very small proporon of pixels may be stuck, either always off (black), always on (red, green, or blue), or
flashing. In addion, over a long period of use, because of the physical characteriscs of the liquid crystal
display, such stuck pixels may appear spontaneously. These problems are not a malfuncon.
If a fixed picture such as a frame of a divided picture or me code, or a sll picture is displayed for a long me,
an image may remain on the screen and be superimposed as a ghosng image.
The permanent burn-in may occur for LCD panel if sll images are displayed in the same posion on the
screen connuously, or repeatedly over extended periods.
To reduce the risk of burn-in,
a. Turn off the character displays.
b. Turn off the power when not in use.
c. Turn off the power if the monitor is not to be used for a prolonged period of me.
