Users Manual

Home Theater Sound Bar RTS739BWSE User Manual Safety Precautions It is important to read this user manual prior to using your new product for the first time. Remote Control Accessories Remote control (with 2 x AAA batteries) ..........................................................................x 1 AC power adapter .....................................................................................................................x 1 Wall Mount Bracket (with screws) .......................................................................................x 2 Please locate the included accessories. To order replacement units, visit http://www.RCAav.com Location of Controls Placement Connections Basic Operation Bluetooth Pairing Troubleshooting Power Supply USing The AC AdAPTeR Using an AC adapter other than the one supplied with the unit may damage the unit. Caution: • Before use, ensure the rated voltage of the adapter matches your local voltage. • The included AC adapter is for use with this unit only. Do not use it with other equipment. • If you are not going to use the unit for a long time, disconnect the AC adapter from the wall outlet. • Whenever the AC adapter is plugged in to a wall outlet, the AC adapter will draw some power, even when the Sound Bar is turned off. USing The RemOTe COnTROL • Point the remote control at the REMOTE SENSOR located on the unit (see Front Panel illustration for precise location). • When there is a strong ambient light source, the perform ance of the infrared REMOTE SENSOR may be degraded, causing unreliable operation. • The recommended effective distance for remote operation is about 16 feet (5 meters). TO ChAnge RemOTe BATTeRieS 1. Open the battery door. 2. Insert two AAA batteries. BATTeRy RePLACemenT When the batteries become weak, the operating distance of the remote control is greatly reduced and you will need to replace them. Notes: • If the remote control is not going to be used for a long time, remove the batteries to avoid corrosion damage caused by battery leakage. • Do not mix old and new batteries. Do not mix ALKALINE, standard (CARBON- ZINC) or rechargeable (NICKEL- CADMIUM) batteries. • Always remove batteries as soon as they become weak. • Weak batteries can leak and severely damage the remote control. • WARNING: Do not dispose of batteries in a fire. batteries may explode or leak. CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type. FCC inFORmATiOn This device complies with Part 15 of the FCC rules.

Bluetooth Module: Antenna Type: Internal, integral antenna Antenna Gain: 0dBi Nominal rated field strength: 98.2dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB 2.4GHz Wireless Module: Antenna Type: Internal, integral antenna Antenna Gain: 0dBi Nominal rated field strength: 91.2dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: For Bluetooth Module: Based on the Maximum allowed field strength of production tolerance was 101.2dBμV/m at 3m in frequency 2.479GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 3.96mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 3.96mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) 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. For 2.4GHz Wireless Module: Based on the Maximum allowed field strength of production tolerance was 94.2dBμV/m at 3m in frequency 2.479GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.79mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.79mW. 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. Simultaneous Transmission SAR exclusion considerations Since the Bluetooth and 2.4GHz Wireless Modules of this device may operate simultaneously, simultaneous transmission analysis is required. Per KDB 447498, simultaneous transmission SAR test exclusion can be applied when the sum of 1-g SAR of all simultaneously transmitting antennas in an operating mode and exposure condition combination is within the SAR limit ( ≤ 1.6W/kg). When the standalone SAR test exclusion is applied, the standalone 1-g SAR must be estimated according to the following equation, Estimated SAR = )max/()5.7/)((TDPxGHzF where F(GHz) is the RF channel transmit frequency in GHz Pmax is the max. power of channel, including tune-up tolerance, mW TD is the min. test separation distance, mm For Bluetooth operation, Maximum Time-averaged Conducted Power of this device = 3.96 mW Therefore, the Estimated SAR will be determined as follow, Estimated SAR = )max/()5.7/)((TDPxGHzF = 0.166 W/kg where Pmax = 3.96mW, TD = 5 mm and F(GHz) = 2.480 GHz For 2.4GHz Wireless Module operation, Maximum Time-averaged Conducted Power of this device = 0.79 mW Therefore, the Estimated SAR will be determined as follow, Estimated SAR = )max/()5.7/)((TDPxGHzF = 0. 033 W/kg where Pmax = 0. 79 mW, TD = 5 mm and F(GHz) = 2.479 GHz Simultaneous Transmission Analysis 2.4GHz Wirelss Module SAR (W/kg) Bluetooth SAR (W/kg) Σ ΣΣ Σ SAR (W/kg) Simultaneous SAR Required 0.033 0.166 0.199 No Conclusion Since the above summed SAR result for all simultaneous transmission conditions were below the SAR limit (1.6 W/kg), SAR evaluation for simultaneous transmission configuration are not required.
