True Wireless Earbuds Instruction Manual ITEM 53858-DI Experience a world without wires with these stylish True Wireless Earbuds. Enjoy balance sound, dynamic range and noise isolation while listen to music or talking on the phone. The battery charging case will charge the earbuds on the go up to 3 full charges. The convenient LED digital readout will let you know when the battery charging case is running low so you can recharge it and never run out of juice. PACKAGE CONTENTS • TWS Earbuds • Charging Case • Type C Charging Cable CHARGING YOUR TWS EARBUDS & CHARGING CASE 1. Please connect the Type C charging cable to the back of the charging case (with the earbuds inside the case) and then to a 5V USB power source and charge for approx. 2 hours. 2. As the Charging Case is charging you are also charging the TWS earbuds inside the case. 3. To recharge the TWS earbud just place them in the charging case. The red LED lights on the TWS earbuds will remain on when charging. Once the earbuds are fully charged the LED will turn OFF. PAIRING THE TWS EARBUDS TO EACH OTHER 1. Remove both TWS earbuds from the Charging Case and wait 5 seconds and they will pair automictically to each other. 2. Note that initially both LED lights on both earbuds will flash green and red and then after 5 seconds the Right earbud will stop flashing and only the Left will continue to flash. This means they are paired to each other. Once this is done you can now pair the earbuds to your phone. 3. Once the TWS earbuds have been connected, when using them again they will automatically connect to each other. PAIRING TWS EARBUDS TO YOUR PHONE (BLUETOOTH) 1. Turn ON your Bluetooth in your Phone settings. 2. Search for Pairing name CJ Tech TWS Earbuds in your phone and connect. Once your phone says connect you are done. 3. Once connected you can now listen to music or have a phone conversion hands-free and totally wire free! CONTROLLING MUSIC & ANSWERING PHONE CALLES You can control the songs/music you are listen to from the TWS earbuds! • Previous/Next Song: Press Left key twice to play the previous music. Press Right key twice to play the next music. You can control your phone call also directly from the earbuds! • Answer/Hang Up: press the left/right earbud button once to answer the phone , and then press the button again to hang up. • Reject a Call: Hold the left/right earbud button 2 seconds to reject call. • Game Mode: Press the left/right earphone button 3 times to enter or exit game mode. • Turn on Siri or Android Voice Assistant: Hold the left/right earbud button for 2-3 seconds, then release the button, start the voice control. Press the earbud button once to turn off the Siri and android voice Assistant. AUTO SHUTDOWN AND MANUAL SHUTDOWN • Auto Shutdown: Put the earbuds into the charging case and they will automatically turn off. • Manual shutdown: Hold the left/right earbud button for 4-5 seconds and you will hear a voice prompt “Power OFF”. The red LED light will remain on for 1 second and then the earbuds will turn OFF. SWITCHING BETWEEN SINGLE AND DUAL EARBUD MODE The factory default is for Dual Earbud mode. When in dual earbud working mode (not connected to the mobile phone), quickly press the left earbud button four times to enter the single earbud mode. Both the red and green lights on the earbuds will flash alternately. Now you are able to use earbuds individually if you desire. In the standby mode of the single earbud mode (not connected to the mobile phone), press the left earbud button four times to enter the dual earbud mode. The left earbud LED light will flash alternately, and the right earbud LED light will turn OFF. You are now back to dual earbud mode.

Hardware version / Software version / Bluetooth Operation frequency 2402MHz ~ 2480MHz Bluetooth Version V5.0 Exposure category General population/uncontrolled environment EUT Type Production Unit Device Type Portable Device 2. Evaluation Method According to KDB447498 D01 General RF Exposure Guidance v06Section 4.3.1 Standalone SAR test exclusion considerations: “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 (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.“ [(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 according to f) in section 4.1 is applied to determine SAR test exclusion. SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD. FCC ID: 2AND8-538TWS This report shall not be reproduced except in full, without the written approval of Shenzhen LCS Compliance Testing Laboratory Ltd. Page 2 of 3 When one of the following test exclusion conditions is satisfied for all combinations of simultaneous transmission configurations, further equipment approval is not required to incorporate transmitter modules in host devices that operate in the mixed mobile and portable host platform exposure conditions. The grantee is responsible for documenting this according to Class I permissive change requirements. Antennas that qualify for standalone SAR test exclusion must apply the estimated standalone SAR to determine simultaneous transmission test exclusion. a) The *∑ of (the highest measured or estimated SAR for each standalone antenna configuration, adjusted for maximum tune-up tolerance) / 1.6 W/kg+ + *∑ of MPE ratios+ is ≤ 1.0. b) The SAR to peak location separation ratios of all simultaneously transmitting antenna pairs operating in portable device exposure conditions are all ≤ 0.04, and the *∑ of MPE ratios+ is ≤ 1.0. 3.
