The device must be connected to an earthed mains socket-outlet.∙Please confirm the power distribution system in the installation site shall provide the circuit breaker rated 120/240V, 20A (maximum).∙Always disconnect the power cord or switch the wall socket off if the device would be left unused for a certain time to achieve zero energy consumption.∙Place the power cord in a way that people are unlikely to step on it. Do not place anything on the power cord.∙If this device comes with an adapter, use only the MSI provided AC adapter approved for use with this device.Environment∙To reduce the possibility of heat-related injuries or of overheating the device, do not place the device on a soft, unsteady surface or obstruct its air ventilators.∙Use this device only on a hard, flat and steady surface.∙To prevent the device from tipping over, secure the device to a desk, wall or fixed object with an anti-tip fastener that helps to properly support the device and keep it safe in place.∙To prevent fire or shock hazard, keep this device away from humidity and high temperature.∙Do not leave the device in an unconditioned environment with a storage temperature above 60℃ or below -20℃, which may damage the device.∙The maximum operating temperature is around 40℃.∙When cleaning the device, be sure to remove the power plug. Use a piece of soft cloth rather than industrial chemical to clean the device. Never pour any liquid into the opening; that could damage the device or cause electric shock.∙Always keep strong magnetic or electrical objects away from the device.∙If any of the following situations arises, get the device checked by service personnel:• The power cord or plug is damaged.• Liquid has penetrated into the device.• The device has been exposed to moisture.• The device does not work well or you can not get it working according to the User Guide.• The device has dropped and damaged.• The device has obvious sign of breakage.TÜV Rheinland CertificationTÜV Rheinland Low Blue Light CertificationBlue light has been shown to cause eye fatigueand discomfort. MSI now offers monitors with TÜVRheinland Low Blue Light certification to ensureusers’ eye comfort and well-being. Please followthe instructions below to reduce the symptoms fromextended exposure to the screen and blue light.∙Place the screen 20 – 28 inches (50 – 70 cm) away from your eyes and a little below eye level.∙Consciously blinking the eyes every now and then will help to reduce eye strain after extended screen time.∙Take breaks for 20 minutes every 2 hours.∙Look away from the screen and gaze at a distant object for at least 20 seconds during breaks.∙Make stretches to relieve body fatigue or pain during breaks.∙Turn on the optional Low Blue Light function.TÜV Rheinland Flicker Free Certification∙TÜV Rheinland has tested this product toascertain whether the display produces visibleand invisible flicker for the human eye andtherefore strains the eyes of users.∙TÜV Rheinland has defined a catalogue oftests, which sets out minimum standardsat various frequency ranges. The test catalogue is based on internationally applicable standards or standards common within the industry and exceeds these requirements.∙The product has been tested in the laboratory according to these criteria.∙The keyword “Flicker Free” confirms that the device has no visible and invisible flicker defined in this standard within the range of 0 - 3000 Hz under various brightness settings.∙The display will not support Flicker Free when Anti Motion Blur/MPRT is enabled. (The availability of Anti Motion Blur/MPRT varies by products.)Regulatory NoticesCE ConformityThis device complies with the requirements set out in the Council Directive on the Approximation of the Laws of the Member States relating to Electromagnetic Compatibility (2014/30/EU), Low-voltage Directive (2014/35/EU), ErP Directive (2009/125/EC) and RoHS directive (2011/65/EU).
