If the primary and secondary devices fail to reconnect in time (more than 10 seconds), user need to click the power button to make the earbud into TWS reconnection mode. (Note: If the primary or auxiliary earbud has never been connected in TWS mode, and the auxiliary earbud has been connected to the second mobile phone alone, user need to clear the pairing record before connect it to the primary earbud normally.) Automatic power-on pairing Open the charging case and take out the earbuds, the two earbuds will automatically enter the TWS search pairing mode (the blue and white lights flash alternately quickly), and then automatically complete the pairing of the earbuds; the primary earbud will automatically enter the mobile phone pairing mode (the blue and white lights flash alternately slowly), the secondary earbud with No lights. If the primary and secondary earbuds fail to reconnect in time (more than 10 seconds), user need to click the power button to make the earbud into TWS reconnection mode. (Note: If the parimary or auxiliary earbud has never been connected in TWS mode, and the auxiliary earbud has been connected to the second mobile phone alone, user need to clear the pairing record before connect it to the primary earbud normally.) Take out any earphone separately from the charging case. If the other earphone is not taken out within 30S, the first earphone will automatically connect back to the mobile phone. If there is no connection record, it will automatically enter the pairing mode. For the primary or secondary earbud, press and hold the power button for 5 seconds to enter pairing mode. If the other earphone is not taken out within 30S, the first earphone will automatically connect back to the mobile phone, if there is no connection record, it will automatically enter the pairing mode Turn on IOS voice assistant(SIRI & Google Assistance Quickly press the left earphone power button three times (after Siri is activated, user can only speak one sentence, then user have to manually click the phone voice, otherwise siri will be automatically turned off) Turn off IOS voice assistant(SIRI & Google Assistance Press the left earphone power button (Apple system only) Turn on entertainment mode (low latency)Press and hold the power button of the left earphone for 1S, and release it when you hear the voice prompt "Entertainment Mode" Turn off entertainment mode (low latency)Press and hold the power button of the left earphone for 1S.

RF Exposure evaluation FCC ID: 2A84F-SL30 1.1. Applicable Standard According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1093 RF exposure requirement KDB447498 v06: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 1.2. Requirement 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. 1.3.

Alternatively, frequency hopping systems operating in the 2400–2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 125 mW. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hop-ping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. EUT Pseudorandom Frequency Hopping Sequence Requirement The pseudorandom frequency hopping sequence may be generated in a nice-stage shift register whose 5 th and 9 th stage outputs are added in a modulo-two addition stage. And the result is fed back to the input of the first stage. The sequence begins with the first one of 9 consecutive ones, for example: the shift register is initialized with nine ones. ● Number of shift register stages:9 ● Length of pseudo-random sequence:29-1=511 bits ● Longest sequence of zeros:8(non-inverted signal) An example of pseudorandom frequency hopping sequence as follows: Each frequency used equally one the average by each transmitter. The system receiver have input bandwidths that match the hopping channel bandwidths of their corresponding transmitter and shift frequencies in synchronization with the transmitted signals.

And according to FCC 47 CFR Section 15.247 (c), if transmitting antennas of directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. Refer to statement below for compliance The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a standard antenna jack or electrical connector is prohibited. Further, this requirement does not apply to intentional radiators that must be professionally installed. Antenna Connected Construction The maximum gain of antenna was 1.95 dBi. Remark:The antenna gain is provided by the customer , if the data provided by the customer is not accurate, Shenzhen CTA Testing Technology Co., Ltd. does not assume any responsibility.
