2AXK8-SP16-1Bluetooth Headset

Instruction Manual 1. Ensure the phone's wireless function is turned off. Remove the earbuds from the charging case—the indicator lights will flash red/blue alternately. Wait for 5 seconds after removal, then the earbuds will automatically enter TWS mode (dual-ear mode). Upon successful connection, one earbud's light will flash red/blue alternately while the other's turns off. 2. Turn on the wireless function of the phone and connect to "SP16". After successful connection, the earbuds' indicator light will turn off. (If only one earbud has sound, first turn off your phone’s wireless function, delete the paired device "SP16", place the earbuds back into the charging case, and then proceed to Step 1.) Connection Method: 1. Short press: Play/Pause, answer calls, end calls; long press to reject incoming calls. 2. Double-tap left/right earbud touch area: Previous/Next Track. 3. Triple-tap left/right earbud touch area: Volume down/Volume up. 4. Long press the earbud touch area for 1.5 seconds: Activate Siri. 5. Press and hold the touch control area for about 3 seconds: Power on/off. Touch Control Function: Touch Control Area The power delivered by the charger must be between min 2.5 Watts required by the radio equipment, and max 10 Watts in order to achieve the maximum charging speed. 2.5 - 10 W FCC Warning This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE 1: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. 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: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. English （英文）

FCC ID: 2AXK8-SP16-1 RF Exposure Evaluation According to KDB 447498 D01 General RF Exposure Guidance v06 and part 2.1093，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(s), listed below, is (are) satisfied. For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(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 Here, The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
