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: 1. Re-orientate or relocate the receiving antenna. 2. Increase the separation between the equipment and receiver. 3. Connect the equipment into an outlet on a circuit different from that of which the receiver is connected. 4. Consult the dealer or an experienced radio / television technical for help. Notice : The changes or modifications not expressly approved by the party responsible compliance could void the user authority to operate the equipment. ISBT42 Initial Setup 1) Plug the charging end of the BluStream FM into your vehicle’s cigarette lighter port, or 12V power outlet 2) The body of the BluStream FM has two important built-in features; a microphone and a control button. a. Attach the body of the BluStream on the dash of the vehicle, using the supplied double-sided tape. NOTE: Location is key. Ideally, the body of the BluStream FM should be placed where it has a clear line-of-sight of the driver. This will provide the best hands-free performance. b. The control button functions are described in the operation section. 3) Pair your Smartphone a. Press and hold the control button on the BluStream FM for 10 seconds to enter pairing mode. The control button on the BluStream FM will rapidly flash Blue when in pairing mode. b. Open the Bluetooth menu on your smartphone and search for available accessories c. Select the BluStream FM from the list and select “Connect” d. With your Bluetooth phone connected to the BluStream FM, begin playback of music and it will stream to your selected FM radio station. Operation 1) Play your music through your vehicle (FM) a. Slide the selector switch on the BluStream FM, to select one of the 4 available FM transmission stations. For best peformance, select a frequency that is not in use by a local radio station in your area. b. Tune your FM radio to the frequency that matches the selected setting on the BluStream FM. c. Begin music playback on your phone, and the audio will play though the vehicle on the selected frequency. 2) Receiving a phone call a. Press the control button once to answer an incoming call, when your phone is ringing. NOTE: you must be on the proper station in order to hear the phone call through the vehicle. Control button The control button on the body of the BluStream FM is used for several different functions, which are described below: - Siri / VR: Press the control button. - Redial: Press the control button twice. - Answer Incoming Phone Call: Press the FM control button, while your phone is ringing. - End call: Press the control button, while in a phone call. USB Charging Port BluStream FM features a 5Volt 1 Amp charging port which can be used to charge your smartphone, or other device. For vehicles equipped with an auxiliary audio input (aux) An audio connection cable is included with the BluStream FM, which allows it to be plugged directly into your vehicle’s auxiliary audio input (if equipped). This will provide superior audio quality, compared to the standard FM output of the BluStream FM. All functions described in the Operation section apply when using the aux connection method. The only difference, is that the radio must be on the aux source, not a specific FM frequency. 1) Plug the smaller end of the aux cable into the body of the BluStream FM 2) Plug the larger end of the aux cable into your vehicle’s aux input NOTE: When using the aux connection method, the setting of the FM selector switch selection on the BluStream does not matter.

RF Exposure Evaluation for XBD-ISBT4 Refer user manual this device is a Bluetooth audio with FM transmitter and charger and this device was designed used in fixed devices the minimum distance between human’s body is 20cm. Based on the 47CFR 2.1093, this device belongs to fixed device. The definition of the category as following: Portable Derives: CFR Title 47 §2.1093(b) (b) For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user. FCC KDB 447498 D01 General RF Exposure Guidance v05r02 Limit Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions. The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. 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, Where  f (GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison  3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below 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. 2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following, and as illustrated in below table: a. [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·( f(MHz)/150)] mW, at 100 MHz to 1500 MHz b. [Power allowed at numeric threshold for 50 mm in step 1) + (test separation distance - 50 mm)·10] mW at > 1500 MHz and ≤ 6 GHz RF Exposure Evaluation Result Table: Evolution Mode Power condition Max. power transmitting Evaluation Frequency(MHz) 2441MHz Peak Conducted power (mW) 1.19 RF Exposure evolution result FCC exclusion condition 1.19mW＜96mW Verdict Pass
