BLU ARIA POD+ Quick Guide Dual-ear mode: Initial use of headsets Take out both left and right earphones from the charging box when using it for the first time. Tear off the film. Put both earphones back into the charging box. The two earphone indicator lights is on. The headset is activated. Basic Operations Automatic power on/off: Open the lid of the charging box, the headset will automatically turn on and the TWS connection is successful. The headsets automatically shut down after 3 minutes of pairing timeout. Put the earphone back into the charging box and close the charging cover. The earphone will automatically shut down after disconnecting the phone and enter the charging state. Product overview 1. Headsets 2. Multifunction key 3. Charging contacts 4. Sound hole 5. Microphone 6. Charging box 7. Charging interface 8. Indicator light Connection: After the left and right earphones are paired, open the cover of the charging box, the white LED of the earphone is flashing quickly. Search for the pairing name on your mobile phone, click Connect, and the phone will have an electronic alert tone if it is successfully connected. 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. Receive a call: When there is an incoming call, you can double-tap either the left earphone (L) or the right earphone (R) to receive the call. Terminate a call: During a call, you can double-tap the left earphone (L) or right earphone (R) to terminate the call. Cancel outgoing call: When the call is made, double-tap the left earphone (L) or right earphone (R) to cancel the outgoing call. Music play/pause: When the music is being played, you can double-tap the left earphone (L) or right earphone (R) to pause the music, or repeat the same action to start playing the music again. Previous Track: Long touch the left earphone (L) for 3 seconds. Next Track: Long touch the right earphone (R) for 3 seconds. Game mode: Touch the headset 3 times to turn on the low-latency mode, accompanied by a "beep-beep" tone, repeat the operation to turn off the low-latency mode, accompanied by a "beep-beep-beep" tone. Automatic re-connection: After the earphone are powered on, they are actively re-connected to the last paired one devices. iOS battery level display: After the earphone is connected to the iOS, the battery level of the earphone can be displayed. 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 white LED light of the connected headset flashes with a "beep" tone, it indicates that the headset is low on power. If you continue to use it, it will automatically shut down. At this time, you need to put the headset back into the charging box to charge. 2.If both the earphone and charging box are out of power, plug in the cable of the charger into the TYP-C 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 earphones are charged in the charging box through two metal contacts. The white LED lights of the earphones are on when charging. It may take about 2 hours to fully charge the battery. After the battery is fully charged, the white LED lights are off. The earphones are ready for use at this time. When the charging box is charging, the white LED light flashes. It may take about 2 hours to fully charge the battery. After the battery is fully charged, the white LED light is always on. At this time, disconnect the charger from the power socket and the charging box. 4.A fully charged battery of earphone can provide about 3.9 hours of talk time, or 94 hours of standby time. The actual talk time and standby time may vary with cell phones, settings, use methods, and environment. FCC Caution. This device complies with part 15 of the FCC Rules.

FCC ID: YHLBLUARIAPD 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: YHLBLUARIAPD Maximum measured transmitter power.
