Please follow the instructions in the Pairing section of this manual. I’ve connected the earbuds with my smartphone but can’t hear any sound Double-check the volume level on your smartphone and the earbuds. Some smartphones require you to set up the earbuds as an audio output device before the audio can be transmitted. If you’re using a music player or other device, please make sure it supports the A2DP profile. The sound isn’t very clear or the caller can’t hear my voice clearly Adjust the volume on your smartphone and the earbuds. Try moving closer to your smartphone to rule out the possibility of interference or wireless range related issues. LED Indicator (Earbuds) Flashing green and red Flashing red Status Pairing mode Low battery - 06 - What’s the wireless range of the earbuds? The maximum range is 10m (33ft). However, the actual range depends on environmental factors. For optimal performance, keep your device connected within a range of roughly 4m to 8m and make sure that there are no major obstacles (like reinforced steel walls) between the earbuds and your device. The earbuds won’t turn on Try charging the earbuds for a while. If the earbuds still won’t power on, please contact our support team at the email address given in ‘Warranty & Customer Support.’ I put the earbuds back in the charging case, but the earbuds are still connected The charging case is probably out of power. Try charging it. Product Care & Use Keep away from liquids and extreme heat. Don’t use the earbuds at high volume for extended periods, as this may cause. Warranty & Customer Support For questions, support, or warranty claims, contact us at the address below that corresponds with your region. Please include your Amazon order number and product model number. Notes When you turn on the earbuds, they will automatically reconnect to the last-paired device or enter pairing mode if no paired device is found. To clear the pairing list, take either of earbuds out of the charging case, and then tap touch-sensitive panel for 7 times, After that, put the earbud back in and take it out again to enter pairing mode. In pairing mode, the earbuds will automatically turn off after 5 minutes if no devices are paired. If one of the earbuds has no sound output, put both earbuds back into the charging case and take them out again. The maximum wireless operating range is 10m (33ft). If you exceed this range, the earbuds will disconnect from your paired device. The connection will be re-established if you re-enter the wireless range within 5 minutes. The earbuds will automatically reconnect to the last-paired device. To connect with other devices, repeat the previous pairing steps. AUTOMATIC CONNECTION Pairing: 1. Turn on the Bluetooth of your mobile phone. 2. Open the charging case, they will automatically turn on and enter the pairing mode. 3. Turn on the pairing function on the device …

Evaluation method and Limit According to KDB447498 D01 General RF Exposure Guidance v06 Section 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.22 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 separaƟon 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 SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD.

Page 2 of 3 mm, a distance of 5 mm according to f) in section 4.1 is applied to determine SAR test exclusion. 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.
