Apparel Please follow the diagram to penetrate the earphone into the ear, press the R<> right ear and LRR<> ear correspondence. Please rotate the headset slightly and adjust to a comfortable angle to ensure that the headset is stable and tight to prevent the headset from falling off. Hang-up: During a call, press the MFB button on the left/right channel headphone once. A beep is prompted. Rejecting a call: When a call comes in, double press the MFB button on the left/right channel headphone. A beep is prompted. Audio transfer: During a call, long press the MFB button on the left/right channel headphone, and release until a beep is prompted. Repeat this operation to transfer the audio between your phone and headset. Answering a call: When a call comes in, press the MFB button on the left/right channel headphone once. Auto redial: In standby or music state, double-click the MFB key on the left or right headset. The auto redial function is enabled, accompanied by a "Beep" sound. Click the MFB key again. The redial function is canceled, accompanied by a "Beep" sound. Music playing/pausing: When the headset is playing music, press the MFB button on the left/right channel headphone once to pause. Repeat this operation to restart playing. Automatic re-connection: After the earphone are powered on, they are actively re-connected to the last paired one devices. Three-way call: During a call, if another call comes in, - Press the MFB button on the left/right channel headphone once to hang up the current call and answer the incoming call. - Double press the MFB button on the left/right channel headphone to keep the current call (A) and answer the incoming call (B). Double press the MFB button again to switch between calls A and B. - During a three-party call, press the MFB button on the left/right channel headphone once to hang up the current call. iOS battery level display: After the earphone is connected to the iOS, the battery level of the earphone can be displayed. Power-off: Press MFB for about 5s (After the TWS pairing mode is completed, any earphone is powered off, the other earphone is powered off at the same time), accompanied by a "Power-off" voice prompt, If the headset is not connected to the mobile phone, both earpieces will be powered off; if the headset is connected to the mobile phone, only one earpiece will be powered off. Enabling/Disabling voice control: In standby or music state, press and hold the MFB key on the left or right headset for about 2 second. The voice control function is enabled, accompanied by a "Beep" sound. You can repeat this operation to disable the voice control function. Anti-lost alarm: When the headset is far away from you or is abnormally disconnected, a voice prompt can be heard. 5 minutes later, the headset will be automatically powered off. Charger and Battery Before using any charger to charge this earphone, check whether the specifications of the charger meet requirements. The recommended output voltage of the charger is DC5V+/-0.25V, and the recommended output current is 100 mA to 500 mA. An over-high charging voltage may damage the earphone. Warning: Use the recommended charger whenever possible. Use of other types of chargers may violate the warranty terms of the equipment and results in danger. If the charging cable is delivered with the earphone, connect the cable to a CCC-certified charger or computer to charge the earphone. Charging the Battery The earphone use embedded charging battery that cannot be removed. Do not attempt to remove the battery from the earphone or the charging box; otherwise, the earphone may be damaged. If the earphone is not used in a long time, keep it in a cool and well-ventilated place, and charge the earphone once every two months. 1.When the LED indicator connected earphone flash red with a voice “please charge”, put the earphone into the charging box. Otherwise the earphone will power off automatically. 2.If both the earphone and charging box are out of power, insert the cable of the charger into the Micro-USB port on the charging box, and plug the charger into the AC socket. The charging box and earphone will be charged simultaneously. 3.The earphone is charged through two metal contacts during charging in the box, and the indicator blinks blue while charging. The full charge takes about two hours. The indicator goes off when the earphone is fully charged. Then you can take out your earphone for use. When the charging box is being charged, the four indicators blink blue in sequence. The full charge takes about two hours. The four indicators become steady blue when the charging box is fully charged. Then you can disconnect the charger from the socket and charging box. 4.A fully charged battery of earphone can provide about 3hours of talk time, or 70 hours of standby time. The actual talk time a…

FCC ID: YHLBLUARIAP RF EXPOSURE EVALUATION METHOD 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. FCC ID: YHLBLUARIAP Maximum measured transmitter power.
