The air purifier will not filter air, and may overheat, causing a fire hazard. • Do not use the air purifier outdoors. • Keep the air purifier away from water, and wet or damp areas. Never place in water or liquid. • Do not use in excessively humid areas. • Keep the air purifier away from heat sources. • Do not use where combustible gases, vapors, metallic dust, aerosol (spray) products, or fumes from industrial oil are present. • Keep 5 ft / 1.5 m away from where oxygen is being administered. • Supervise children when they are near the air purifier. • Do not place anything into any opening in the air purifier. • Do not sit or place heavy objects on the air purifier. • Keep the inside of the air purifier dry. To prevent moisture buildup, avoid placing in rooms with major temperature changes or underneath air conditioners. • Always unplug the air purifier before servicing (such as changing the filter). • Do not use the air purifier if it is damaged or not working correctly, or if the cord or plug is damaged. Do not try to repair it yourself. Contact Customer Support (see page 19). To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines. General Safety • Keep the air purifier near the outlet it is plugged into. • Never place the cord near any heat source. • Do not cover the cord with a rug, carpet, or other covering. Do not place the cord under furniture or appliances. • Keep the cord out of areas where people walk often. Place the cord where it will not be tripped over. • This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature. Electromagnetic Fields (EMF) Your Levoit air purifier complies with all standards regarding electromagnetic fields (EMF). If handled properly and according to the instructions in this user manual, the appliance is safe to use based on scientific evidence available today. Power & Cord READ AND SAVE THESE INSTRUCTIONS • WARNING: To reduce the risk of fire or electric shock, do not use this air purifier with solid-state speed controls (such as a dimmer switch). • Not for commercial use. Household use only. 4 GETTING TO KNOW YOUR SMART AIR PURIFIER A. Fan Speed Indicators B. Fan Speed Button C. Sleep Mode Button D. Air Quality Indicator Rings E. Check Filter Indicator Reset Button F.

RF EXPOSURE EVALUATION According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) Radiation as specified in §1.1307(b) Limits for Maximum Permissible Exposure (MPE) MPE Calculation Method Friis transmission formula: Pd= (Pout*G)\ (4*pi*R 2 ) Where Pd= Power density in mW/cm2 Pout=output power to antenna in mW G= Numeric gain of the antenna relative to isotropic antenna Pi=3.1415926 R= distance between observation point and center of the radiator in cm(20cm) Pd the limit of MPE, 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. - Page 4 of 6 - Report No.: MTi201225003-03E4 Tel:(86-755)88850135 Fax: (86-755) 88850136 Web: http://www.mtitest.com E-mail: [email protected] Address: 101, No. 7, Zone 2, Xinxing Industrial Park, Fuhai Avenue, Xinhe Community, Fuhai Street, Bao’ an District, Shenzhen, Guangdong, China.
