Package Contents 1 x Smart Ultrasonic Top-Fill Cool Mist Humidifier 3 x Aroma Pads (1 Pre-Installed) 1 x Cleaning Brush 1 x User Manual 1 x Quick Start Guide 3 SAFETY INFORMATION • Only use the humidifier as described in this manual. • Place the humidifier and cord so that it will not be knocked over. Do not place near large pieces of furniture or in high- traffic areas. • When not in use, turn the humidifier off and disconnect from power by removing the plug from the outlet. • Do not use the humidifier in wet environments. • Keep the humidifier out of reach from children. • Do not open the base or remove the water level sensor for self-servicing. • Always unplug your humidifier from the power outlet before cleaning your humidifier or detaching the water tank from the humidifier base. • Always make sure to place the humidifier on a flat, level surface before operation. • Only fill the water tank with clean water. Never fill the water tank with any other liquids. • Do not place the humidifier near sources of heat, such as stovetops, ovens, or radiators. • Do not place the humidifier directly on floors, carpets, or rugs. To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines. General Safety • Do not use other items as replacement parts for this product. • Do not cover the nozzle while the humidifier is on. Doing so may damage the humidifier. • Remove the water tank from the base before moving the humidifier. • Do not immerse the humidifier base, power cord, or plug in water. • If the humidifier is damaged or is not functioning properly, stop using it and contact Customer Support immediately (see page 27). • Not for commercial use. Household use only. • Do not add essential oils, supplemental water treatment liquids, or water filters into the water tank or base chamber. This will damage the humidifier and cause leaks. Only add essential oils to the aroma pad. Caution: Risk of Leaks and Electric Shock READ AND SAVE THESE INSTRUCTIONS 4 Plug & Cord • Ensure that the plug fits properly into a polarized socket. • Do not handle the power cord or plug with wet hands. Keep the plug and power cord away from liquids. • Your humidifier has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature. SAFETY INFORMATION (CONT.) 5 GETTING TO KNOW YOUR SMART HUMIDIFIER A. Nozzle B. Water Tank Cover C. Dust Cover D. Mist Tube E. Water Tank F. Night Light G. Base H.

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 5 - Report No.: MTi20082408-1E4 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.
