Safety Precautions, Maintenance & Recommended Use English Safety Precautions and Maintenance FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE FOLLOWING WHEN SETTING UP AND USING THE MULTI-FUNCTION MONITOR: • DO NOT OPEN THE MONITOR. There are no user serviceable parts inside and opening or removing covers may expose you to dangerous shock hazards or other risks. Refer all servicing to qualified service personnel. • Do not bend, crimp or otherwise damage the power cord. • Do not place any heavy objects on the power cord. Damage to the cord may cause shock or fire. • Fasten the power cord to the monitor by attaching the screw and clamp to prevent loose connection. (Recommended Fasten Force: 139 - 189 N•cm). • Please make sure that enough power is supplied to the monitor. Please refer to the "Power Supply" in the specifications. • The power supply cord you use must have been approved by and comply with the safety standards of your country. (e.g. Type H05VV-F 3G 1 mm2 should be used in Europe). • In the UK use a BS-approved power cord with a molded plug having a black (5 A) fuse installed for use with this monitor. • The power cord connector is the primary means of detaching the system from the power supply. The monitor should be installed close to a power outlet that is easily accessible. • Do not spill any liquids into the cabinet or use your monitor near water. • Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which can be harmful or fatal, or may cause electric shock, fire or equipment failure. • Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall, causing serious damage to the monitor. • Do not mount this product face up, face down, or upside down for an extended period of time as it may cause permanent damage to the screen. • Do not use the monitor outdoors. • If glass is broken, handle with care. • This monitor is equipped with temperature control fans. For reliable performance and long life use of this product, it is required that the vents on the monitor are not covered. • If the monitor or glass is broken, do not come in contact with the liquid crystal and handle with care. • Allow adequate ventilation around the monitor, so that heat can properly dissipate. • Do not block ventilated openings or place the monitor near a radiator or other heat source. • Do not put anything on top of the monitor. • Handle with care when transporting. Save packaging for transporting. • When running the cooling fan continuously, we recommend wiping clean the ventilation holes a minimum of once a month. • To ensure the monitor's reliability, please clean the ventilation holes at the rear side of the cabinet at least once a year to remove dirt and dust. • When using a LAN cable, do not connect to a peripheral device with wiring that might have excessive voltage. • Do not use the monitor in high temperature, humid, dusty, or oily areas. • Do not use the monitor under rapid changes in temperature and humidity, and avoid cold air directly from an air-conditioning vent. These conditions may shorten the life of the monitor or cause condensation. If water condensation has occurred, unplug the monitor and do not use the monitor until the condensation has evaporated. Connecting to a TV*1 • Cable distribution system should be grounded (earthed) in accordance with ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable. • The screen of the coaxial cable is intended to be connected to earth in the building installation. Under the following conditions immediately disconnect your monitor from the wall outlet and refer servicing to qualified service personnel: • If the power supply cord or plug is damaged. • If liquid has spilled or objects have fallen into the monitor. • If the monitor has been exposed to rain or water. • If the monitor has been dropped or the cabinet has been damaged. • If you notice any structural damage such as cracks or unnatural wobbling. • If the monitor does not operate normally by following operating instructions. *1: The product you purchased may not have this feature. Recommended Use Ergonomics To realize the maximum ergonomic 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). • Rest your eyes periodically by focusing on an object at least 5 feet away. Blink often. • Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections. English−3
