SUBWOOFER SBT1739-SWE USER ManUal It is important to read this instruction book prior to using your new product for the first time. The lightning flash with an arrowhead symbol, within the equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to cause an electric shock. The symbol for Class II (Double Insulation) SaFETY InSTRUCTIOnS On PlaCEMEnT • Do not use the unit in places that are extremely hot, cold, dusty, or humid. • The ventilation should not be impeded by covering the ventilation openings with items such as newspaper, table-cloths, curtains, etc. On SaFETY • When connecting or disconnecting the AC power cord, grip the plug and not the cord itself. Pulling the cord may damage it and create a hazard. • When you are not going to use the unit for a long period of time, disconnect the AC power cord. • No naked flame sources such as lighted candles should be placed on the AC power cord and the unit. • Leave a minimum of 10 cm around the apparatus for ventilation. • Attention should be drawn to the environmental aspects of battery disposal. • Use of apparatus in moderate climates. On COndEnSaTIOn • When left in a heated room where it is warm and damp, water droplets or condensation may form inside the unit. When there is condensation inside the unit, the unit may not function normally. Let the unit stand for 1 to 2 hours before turning the power on, or gradually heat the room and let the unit dry before use. RaTIng PlaTE lOCaTIOn • The rating plate is located at the rear of unit. WARNING: • Should any trouble occur, disconnect the AC power cord and refer servicing to a qualified technician. • Mains plug is used as the disconnect device, it shall remain readily operable and should not be obstructed during intended use. To be completely disconnected the apparatus from supply mains, the mains plug of the apparatus shall be disconnected from the mains socket outlet completely. FCC InFORMaTIOn NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. WARNING: THE APPARATUS SHALL NOT BE EXPOSED TO DRIPPING OR SPLASHING AND THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, SHALL BE PLACED ON APPARATUS. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THE APPLIANCE TO RAIN OR MOISTURE. CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

Version 1.01 Page 1 of 13 GWK5NO_SW_TX Datasheet GWK5NO_SW 2.4GHz Wireless Subwoofer Module 1. General Description GWK5NO_SW is the optimized module dedicated for the wireless subwoofer application, it balance well between the cost and performance by utilizing the fact of subwoofer limited frequency response bandwidth. The narrow bandwidth enables GWK5NO_SW to transmit enough redundant data to combat with the 2.4GHz interference thus maintain the good co-existence performance in the 2.4GHz ISM band. Inheriting from its GWK5 family, GWK5NO_SW features both good wireless performance and audio performance. GWK5NO_SW has good RF co-existence and robust link quality, can combat the most interference from the crowded 2.4G ISM band. GWK5NO_SW uses non-compression PCM signal and 24bit high precision thus delivering very low THD audio. By adopting advance forward error correction and error concealment algorithm, GWK5NO_SW can reach <20ms latency, this makes it ideal for the Video synchronization, Home Theater applications. GWK5NO_SW is ideal for the subwoofer application not only by its competitive cost, but also by its flexibility for customized functions. The SW crossover frequency can be adjusted easily by the digital filter, and the general purpose I2C can be used to control customer peripheral unit to eliminate an extra microcontroller. 2.

The audio signal can be sent via the 2.4GHz Digital wireless modules, which are incorporated in both soundbar unit and subwoofer unit. The EUT is powered by 120VAC mains. Antenna Type: Internal, integral antenna Antenna Gain: 0dBi Nominal rated field strength: 92.0dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 95.0dBμV/m at 3m in frequency 2.479GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.949mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.949mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.479) mW = 9.53 mW Since the above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
