FAQ 友情提示1：请每周为充电盒充电一次，避免充电盒过度放电； 友情提示2：使用一段时间后，由于充电触点存在脏污或氧化，导致耳机无法 充电甚至无法开机，您可以使用消毒棉签蘸取酒精擦拭耳机充电触点和充电盒充 电触点来解决此问题； Friendly reminder 1: Please recharge the charging case once a week to avoid over-discharge. Friendly reminder 2: After using for a period of time, the charging contacts may get dirty or oxidized, thus the headphones cannot be charged or turned on. You can use a disinfection cotton swab dipped with alcohol to clean the charging contacts of the headphones and the charging pins of the charging case to solve this problem. Q： 耳机连接不上如何解决？ A： ①有可能是耳机低电，请将两只耳机都放入充电盒充电，30分钟后取出尝 试重新搜索连接； ②若您是IOS系统，有可能是耳机没有及时回连您的手机，您可检查手机蓝 牙列表中是否已存在设备名“Joyroom Openfree OE2”，请直接点击设备名连接； ③请检查耳机是否已经连接上了其他设备，请在其他设备上断开连接后再尝 试重新搜索连接； ④若以上操作无效，您可以对耳机进行恢复出厂设置。 Q: Why can’t the headphones be connected? A: ① The headphones may be out of power. Please charge them for 30 minutes in the charging case before turning them on, and then search them for connection. ② If your phone uses iOS system, it may be that the headphones did not reconnect to your phone in time. You can check whether the device name "Joyroom Openfree OE2" is in the phone’s BT list. If so, please directly click the device name for connection. ③ Check whether the headphones are connected to another device. If so, please disconnect with it and make a reconnection again. ④ If above operations failed, you can restore them to factory settings. 充电盒电量显示 （充电盒多功能 按键按下时） Displaying case battery level (when the multifunctional button of the case is pressed down) 1.电量31%-100%：白灯长亮5秒 2.电量11%-30%：橙灯…

RF EXPOSURE EVALUATION METHOD FCC ID: 2AWL2-JROE2 Applicable standard： In accordance with FCC 47 CFR part 2 (2.1093) this device has been defined as a portable device which 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. Portable devices must be evaluated using the specified in FCC 47 CFR part 2 (2.1093) and ANSI/IEEEC95.1-1992. and had been tested in accordance with the measurement methods and procedures specified in IEEE 1528-2003. Per FCC KDB 447498 D01 v06, the 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances s 50 mm are determined by: SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm Approximate SAR Test Exclusion Power Thresholds at Selected Frequencies and Test Separation Distances are illustrated in the following Table. 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 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.

[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] * [√f(GHz)] < 3.0. 2. SAR Test Exclusion Thresholds is 3.0 for separation distance 5mm. Therefore, SAR test is not required.

Number Of Hopping Frequency 13.1 Block Diagram Of Test Setup 13.2 Limit Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 channels. 13.3 Test procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum. 2. Set the spectrum analyzer: RBW = 100kHz. VBW = 300kHz. Sweep = auto; Detector Function = Peak. Trace = Max hold. 3. Allow the trace to stabilize. It may prove necessary to break the span up to sections. in order to clearly show all of the hopping frequencies. The limit is specified in one of the subparagraphs of this Section. 4. Set the spectrum analyzer: Start Frequency = 2.4GHz, Stop Frequency = 2.4835GHz.

Dwell Time 14.1 Block Diagram Of Test Setup 14.2 Limit Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 channels. The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Frequency hopping systems may avoid or suppress transmissions on a particular hopping frequency provided that a minimum of 15 channels are used. 14.3 Test procedure 1. Remove the antenna from the EUT and then connect a low RF cable from the antenna port to the spectrum. 2. Set spectrum analyzer span = 0. Centred on a hopping channel; 3. Set RBW = 1MHz and VBW = 3MHz.Sweep = as necessary to capture the entire dwell time per hopping channel. Set the EUT for DH5, DH3 and DH1 packet transmitting. 4. Use the marker-delta function to determine the dwell time. If this value varies with different modes of operation (e.g.. data rate. modulation format. etc.). repeat this test for each variation. The limit is specified in one of the subparagraphs of this Section. Submit this plot(s). 14.4 Test Result DH5 Packet permit maximum 1600 / 79 / 6 hops per second in each channel (5 time slots RX, 1 time slot TX). DH3 Packet permit maximum 1600 / 79 / 4 hops per second in each channel (3 time slots RX, 1 time slot TX). DH1 Packet permit maximum 1600 / 79 /2 hops per second in each channel (1 time slot RX, 1 time slot TX). So, the Dwell Time can be calculated as follows: DH5:1600/79/6*0.4*79*(MkrDelta)/1000 DH3:1600/79/4*0.4*79*(MkrDelta)/1000 DH1:1600/79/2*0.4*79*(MkrDelta)/1000 Remark: Mkr Delta is once pulse time.
