No user-serviceable parts inside. Refer servicing to qualified personnel only. Explanation of Graphical Symbols: The lightning flash within an equilateral triangle is intended to alert you to the presence of uninsulated dangerous voltage within the product's enclosure that may be of sufficient magnitude to constitute an electric shock to a person or persons. The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. English 2 WARNINGS: 1. Read Instructions - All the safety and operating instructions must be read before the product is operated. 2. Retain Instructions - The safety and operating instructions should be kept with the product for future reference. 3. Heed warnings - All warnings on the product and in the operating instructions should be adhered to. 4. Follow instructions - All operating and users instructions should be followed. 5. Installation - Install in accordance with the manufacturer's instructions. 6. Power sources - This product should be operated only from the type of power source indicated by the marking adjacent to the power cord entry. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. 7. Grounding or polarization - the product is not required to be grounded. Ensure the plug is fully inserted into the wall outlet or extension cord receptacle to prevent blade or pin exposure. Some versions of the product are equipped with a power cord fitted with a polarized alternating line plug (a plug having one blade wide than the other). This plug will fit onto the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarized plug. When using an extension power-supply cord or a power-supply cord other than that supplied with the product, it should be fitted with the appropriate molded plugs and carry safety approval appropriate to the country of use. 8. Power cord protection - Power-supply cords should be routed so that they are not likely to be walked on, kinked or pinched by items placed on or against them, paying particular attention to cords from plugs, receptacles and the point where they exit from the appliance. 9. Overloading - Do not overload wall outlets, extension cords or multiple sockets, as this can result in a risk 80-MD220-97-0001-01 2012-02-07 80-MD212-97-0001-01 2012-11-12 of fire or electric shock. 10. Ventilation - The product must be properly ventilated. Do not place the product on a bed, sofa, or other similar surface. Do not cover the product with any items such as tablecloths, newspapers, etc. 11. Heat - The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products including amplifiers that produce heat. No naked flame sources, such as lighted candles, should be placed on the apparatus. 12. Water and moisture - To reduce the risk of fire or electric shock, do not expose the product to train, dripping, splashing or excessive moisture such as in a sauna or bathroom. Do not use this product near water, for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, or etc. 13. Object and Liquid Entry - Never push objects of any kind into this product through openings, as they may touch dangerous voltage points or short-circuit parts that could result in a fire or electric shock. Never spill liquid of any kind on the product. Do not place any object containing liquid on top of the product. 14. Cleaning - Unplug the product from the wall outlet before cleaning. The cabinet of the subwoofer may be cleaned by dusting with a dry cloth. If you wish to use an aerosol cleaning spray, do not spray directly on the cabinet; spray onto the cloth. Be careful not to damage the drive units. 15. Attachments - Do not use attachments not recommended by the product manufacturers, as they may cause hazards. 16. Accessories - Do not place this product on an unstable cart, stand, tripod, bracket or table. The product may fall, causing serious injury to a child or adult, and serious damage to the product. Use only with a cart, stand, tripod, bracket or table recommended by the manufacturer or sold with the product. Any mounting of the product should follow the manufacturers’ instructions and should use a mounting accessory recommended by the manufacturer. 17. Moving the product - A product and cart combination should be moved with care. Quick stops, excessive force and uneven surfaces may cause the product and cart combination to overturn. 18. Un-use periods - The power cord of the device should be unplugged from the outlet during lightning storms or when the apparatus is left unused for a long period of time. 19. Servicing - Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous voltage or oth…

Microlab MULTIMEDIA SPEAKER FCC ID: OR8-MD212 USB: 5V 500mA This device complies with Part 15 of FCC rules. Operation is subject to the following two conditions: (1) This device may not cause interference, and (2) This device must accept any interference, including interference that may cause undesired operation of the device

Antenna

FCC ID : OR8-MD212 1. RF EXPOSURE 1.1. The Requirement System operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See Section 15.247(b)(4) and Section 1.1307(b)(1) 1.2. Limit For Maximum Permissible Exposure (MPE) Limits for General Population/ Uncontrolled Exposure F = frequency in MHz, * Plane-wave equivalent power density 1.3. MPE Calculations E(V/m) = 30 P G d  , Power Density: S( 2 mW/cm) = 2 377 E Where E = Electric Field (V/m) P = Peak Output Power (mW) Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) ( 2 mW/cm) Averaging Time 2 E, 2 H or S (minutes) 0.3-1.34 614 1.63 (100)* 30 1.34-30 824/f 2.19/f (180/f)* 30 30-300 27.5 0.073 0.2 30 300-1500 f/1500 30 1500-100,000 1.0 30 G = Antenna Numeric Gain (numeric) = 10 x , x = Antenna Gain(dBi) /10 d = Separation Distance (cm) We can change the formula to: S = 2 30 377 PG d   or, d = 30 377 PG S   Because the EUT is belong to general population/uncontrolled exposure. So 1.3.1. We considering the limit of minimum separation distance (d) is 20cm, Maximum Output Power = 0.675mW Antenna Gain = 2.5(dBi) = 1.78(numeric) S = 2 30 377 PG d   = 0.00024 2 mW/cm < 1.0 2 mW/cm (limit) Calculated RF Exposure power density is 0.00024 2 mW/cm , less than the limit. 1.3.2. We considering the limit of power density (S) is 1.0 2 mW/cm , Maximum Output Power = 0.675mW Antenna Gain = 2.5(dBi) = 1.78(numeric) d = 30 377 PG S   = 0.31 cm < 20 cm Calculated RF Exposure separation distance is 0.35 cm, less than the minimum separation distance 1.3.3.FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, Human proximity to the antenna shall not be less than 20cm(8 inches) during normal operation. Proposed RF exposure safety information to include in User’s Manual.
