Computer As Source and Bluetooth Audio System NE-830 User's Manual 2 Important Safety Instructions When used in the directed manner, this unit has been designed and manufactured to ensure your personal safety. However, improper use can result in potential electrical shock or fire hazards. Please read all safety and operating instructions carefully before installation and use, and keep these instructions handy for future reference. Take special note of all warnings listed in these instructions and on the unit. 1. Water and Moisture The unit should not be used near water. For example: near a bathtub, washbowl, kitchen sink, laundry tub, swimming pool or in a set basement. 2. Ventilation The unit should be situated so that its location or position does not interfere with its proper ventilation. For example, it should not be situated on a bed, sofa, rug or similar surface that may block the ventilation openings. The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-cloths, curtains, etc. Also, it should not be placed in a built-in installation, such as a bookcase or cabinet, which may impede the flow of air through the ventilation openings; minimum distances 30 cm around the apparatus for sufficient ventilations. 3. Heat & Flame The unit should be situated away from heat sources such as radiators, heat registers, stoves or other appliances (including amplifiers) that produce heat. No naked flame sources, such as lighted candles, should be placed on the apparatus. 4. Power Source The unit should be connected to a power supply only of the type described in the operating instructions or as marked on the appliance. Where the power adaptor is used as the disconnect device, the disconnect device shall remain readily operable. 5. Power Cord Protection Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them. It is always best to have a clear area from where the cord exits the unit to where it is plugged into an AC outlet. The mains plug of apparatus should not be obstructed OR should be easily accessed during intended use. 6. Cleaning The unit should be cleaned only as recommended. See the section "Care and Maintenance" of this manual for cleaning instructions. 7. Object and Liquid Entry Care should be taken so that objects do not fall and liquids are not spilled into any openings or vents located on the unit. It shall not be exposed to dripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the apparatus. 8. Attachments Do not use attachments no recommended by the product manufacturer. 9. Lightning and Power Surge Protection Unplug the unit from the wall outlet and disconnect the periods of time. This will prevent damage to the product due to lightning and power-line surges. 10. Overloading Do not overload wall outlets, extension cords, or integral convenience receptacles as this can result in a risk of fire of electric shock. 11. Damage Requiring Service This unit should be serviced by qualified service personnel when: A. The power supply cord or plug has been damaged. B. Objects have fallen into or liquid has been spilled into the enclosure. C. The unit has been exposed to rain. D. The unit has been dropped or the enclosure damaged. E. The unit exhibits a marked change in performance or does not operate normally. 12. Periods of Nonuse If the unit is to be left unused for an extended period of time, such as a month or longer, the power cord should be unplugged from the unit to prevent damage or corrosion. 13. Servicing 3 The user should not attempt to service the unit beyond those methods described in the user's operating instructions. Service methods not covered in the operating instructions should be referred to qualified service personnel. 14. Environment Attention should be drawn to the environment aspects of battery disposal and the use of apparatus in moderate climates. Warnings: - Battery shall not be exposed to excessive heat such as sunshine, fire or the like. - Be sure that the battery are installed correctly. Wrong polarity may damage the unit. - Do not mix old and new batteries. - Do not mix alkaline, standard (carbon-zinc) or rechargeable (nickel-cadmium) batteries. - Only batteries of the same or equivalent type as recommend are to be used. - If the unit is not to be used for an extended period of time, remove the battery. - Do not dispose of batteries in fire, battery may explode or leak. - Danger of explosion if battery is incorrectly replaced.

ANTENNA

FCC ID : 2AE3J-MP-830 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems 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 level in excess of the Commission’s guidelines. According to KDB 447498 D01 General RF Exposure Guidance v05, section 4.3.1 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, 16 where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation 17 The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
