This portable wireless speaker set is powered by li-ion rechargeable battery with a built-in battery capacity of 200mAh on each portable wireless speaker and 1000mAh on charging stand. 2. Charging the charging stand: Use the USB charging cable provided and insert the micro USB plug into the charging stand micro USB input port. Insert the other side of the USB plug to the power bank (not included), notebook or PC’s USB port. The charging stand LED light indicators will turn on in blue and start flashing. Once the charging stand is fully charged (it will take approx. 2-h o u r, depending on the charging equipment), all charging stand 4-LED indicators will turn on in blue color and stop flashing. Once the charging stand is fully charged, remove the micro USB plug from the charging stand micro USB input port and remove the USB plug from the power bank (not included), notebook or PC’s USB port immediately. Energy of charging stand: 1-LED indicator turned on in blue = Approx. 25% energy. 2-LED indicators turned on in blue = Approx. 50% energy. 3-LED indicators turned on in blue = Approx. 75% energy. All 4-LED indicators turned on in blue = Approx. 100% energy. 3. Charging the portable wireless speaker set: Place the two portable wireless speakers into the charging stand. The left and right portable wireless speaker charging LED indicators will turn on in red. At the same time, the charging stand LED indicator (s) will also turn on in blue. Once the portable wireless speaker (s) is fully charged (it will take approx. 1.5-hour), the portable wireless speaker charging LED indicator (s) will turn off. At the same time, the charging stand LED indicator (s) will turn off too. Note: Both portable wireless speakers may not fully charged at the same time. 4. When the portable wireless speaker set under operation, if you hear a message “Battery low” frequently from both speakers or any one of speaker, it means that speaker (s) battery power is almost exhausted. Please re-charge the speaker (s) immediately. NOTE: If the battery power of both portable wireless speakers or any one speaker is totally exhausted, the speaker (s) and the speaker’s LED indicator (s) will turn off automatically. To pair the portable wireless speaker set and connect to the wireless device: 1. To pair the portable wireless speaker set. Press and hold the portable wireless speaker set power ON/OFF button (on the charging stand) in approx. 2-second. You will hear a short melody and both portable wireless speakers of 2-LED indicators (on the bottom of each speaker) will turn on in blue color and flashing. After approx. 5-second, both portable wireless speakers will connect together automatically and you will hear an audible sound. To connect the wireless device. Turn on the wireless mode from the smartphone, tablet, or any other devices, which have wireless mode function. Search the pairing name of "18830" and confirm pairing. The portable wireless speaker set will connect to the wireless device successfully and you will hear an audible sound from the portable wireless speaker set. Press the portable wireless speaker set protection cover open button once. The protection cover will open. N o w, y ou can enjoy the music from the portable wireless speaker set. Or, you can take out both portable wireless speakers from the charging case and placed on the flat area. Note: The portable wireless speaker set has an automatic wireless connection function. When a connected smartphone, tablet, or other wireless device turns on the wireless function, the portable wireless speaker set will actively connect to the last connected device. 2. If the portable wireless speaker set fails to pair, it may be paired with another mobile, tablet or device. In this case, deactivate the wireless function from your mobile, tablet or other device and reactivate the wireless function again. Repeat the above steps for pairing. It should work. 3. The portable wireless speaker set will auto power off in approx. 5-minute if there is no connection to the wireless device. You will hear an audible sound and all LED indicators on the portable wireless speaker set will turn off. 4. Use a single portable wireless speaker: If you just wanted to use a single portable wireless speaker, press the portable wireless speaker set protection cover open button once. The protection cover will open. Take out any one powered off portable wireless speaker from the charging stand. Press and hold the portable wireless speaker power ON/OFF button (on the bottom of speaker) in approx. 2-second.

Page 1 of 3 FCC RF Exposure Evaluation 1. Product Information FCC ID: 2ACO3‐18830 Product name Portable wireless speaker set Test Model #18830 Power supply Input: DC 5V, 310mA DC 3.7V by Rechargeable Li‐ion Battery,200mAh BOX: DC 3.7V by Rechargeable Li‐ion Battery,1000mAh Modulation Type GFSK, π/4‐DQPSK for Bluetooth V5.1 (DSS) Antenna Type PCBAntenna Antenna Gain ‐0.68dBi(maximum) Hardware version / Software version / Bluetooth Operation frequency 2402MHz‐2480MHz Bluetooth Version V5.1 Exposure category General population/uncontrolled environment EUT Type Production Unit Device Type Portable Device 2. Evaluation Method According to KDB447498 D01 General RF Exposure Guidance v06Section 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. 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 mm, a distance of 5 mm according to f) in section 4.1 is applied to determine SAR test exclusion. SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD. FCC ID: 2ACO3‐18830 This report shall not be reproduced except in full, without the written approval of Shenzhen LCS Compliance Testing Laboratory Ltd. Page 2 of 3 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 esƟmated SAR for each standalone antenna configuraƟon, adjusted for maximum tune‐up tolerance) / 1.6 W/kg] + [∑ of MPE raƟos] is ≤ 1.0. b) The SAR to peak location separation ratios of all simultaneously transmitting antenna pairs operaƟng in portable device exposure condiƟons are all ≤ 0.04, and the [∑ of MPE raƟos] is ≤ 1.0. 3.
