Power

Operate the monitor only with the indicated power source. Ensure the three-pronged plug is used in a grounded outlet. Unplug during lightning storms or long periods of non-use. Do not overload power strips or extension cords. Use only UL-listed computers with appropriate receptacles (100-240V AC, Min. 5A). The wall socket should be near the equipment and easily accessible.

Installation

Do not place the monitor on unstable surfaces. Use only manufacturer-recommended carts, stands, or tables. Never insert objects into monitor slots or spill liquids. Do not place the product on the floor. If wall-mounting, use an approved kit and follow instructions. Ensure adequate ventilation around the monitor (at least 4 inches / 10cm clearance). Avoid tilting the monitor downward by more than -5 degrees to prevent panel damage.

Cleaning

Clean the cabinet with a water-dampened, soft cloth. Use a damp, almost dry microfiber cloth. Do not allow liquid into the case. Disconnect the power cord before cleaning.

Other Precautions

If the product emits strange smells, sounds, or smoke, disconnect the power plug immediately and contact a service center. Ensure ventilating openings are not blocked. Do not expose the monitor to severe vibration or high impact. Do not knock or drop the monitor during operation or transportation.
