Turn the Earbuds OFF by pressing the control surface on each earbud until the LED blinks red, and then turns off. 2. Replace the earbuds in the case. Turn your device's Bluetooth® OFF and then back ON. Then repeat the pairing process. Charging 1. Replace the earbuds in the case. 2. Connect the USB-C charging cable to the charging port on the back of the case. 3. Plug the cable into a standard USB SV/lA or higher power output. When you plug the case into a charging mechanism, the LED case display will show the battery blocks filling. This means the case battery is being charged. While this is happening the lights on the buds inside the case will be off. The charge display will stop blinking when fully charged and shut off if the case is unplugged from the power source. 4. When fully charged, unplug the charging cable from the power source. If want to charge the earbuds from the charge case internal battery, simply replace them in the case. The charge display on the top of the case turns on, showing the internal charge available.

FCC ID: 2AHN6-AUBE209 FCC RF Exposure Evaluation Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Portable device Refer Standard: KDB 447498 D01 General RF Exposure Guidance v06 FCC Part 2 §2.1093 Evaluation method 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.23 “ [(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 5) in section 4.1 is applied to determine SAR test exclusion.
