Battery low: LED flashes red per 30seconds and prompt “battery low”. Charge the charging case: 1. Plug the provided Type-C charging cable into the bottom of charging case, the LED light will turn green breathing while charging then turn solid green once charging complete. If the charging case is in low battery, the LED flashes white. Charging time for charging case: around 2hours 2. The charging case support wireless charging function Put the charging case on the charging pad to do wireless charging Bluetooth Pairing Open the charging case, the earbuds will begin auto-pairing with each other. The earbuds LED will flash red and blue and going to device pairing mode. Activate the Bluetooth function on your device to search for “RT62AE” and connect it. It is ready to use. ENC Tech The ENC (Environmental Noise cancellation tech) algorithm cancels the background noise so that you can be heard crystal clear via voice calls. The earbuds are equipped with 4 mics and the ENC already activated by default during calling. Single earbuds usage Each earbud can be used independently. Calling/ Music: Answer/ END call: Touch L/R earbud twice： Rejecting an incoming call: Touch and hold L/R earbud 2 seconds until you hear a prompt tone ”du”: Play/Pause: Touch L/R earbud twice Next song: Touch R earbud 3 times Previous song: Touch L earbud 3 times: Voice Assistant: Touch and hold L earbud for 2 seconds until you hear a prompt sound to active the Voice Assistant/ Siri function. This function may not work for all devices. ANC Function Transparency ON: Touch and hold R earbud for 2 seconds ANC ON: Touch and hold R earbud for 2 seconds ANC OFF: Touch and hold R earbud for 2 seconds Power off: Method 1: Place the earbuds back into the charging case. Method 2: Touch and hold the earbuds for 5seconds until you hear prompt” Power off” Reset Earbuds Place L/R earbuds into the charging case, keep the case open and touch the reset button on the charging case for 5s-7s. This clears all connection records and all device. Remark: TWS without connecting any device within 5mins, it will power off automatically.

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. 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. NOTE: 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. This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter. Radiation Exposure Statement The device has been evaluated to meet general RF exposure requirement in portable exposure condition without restriction.

Shenzhen Tongzhou Testing Co.,Ltd FCC ID: 2ATOY-RT612AE This report shall not be reproduced except in full, without the written approval of Shenzhen Tongzhou Testing Co.,Ltd Page 1 of 3 RADIO FREQUENCY EXPOSURE Limit According to section B.4 of 447498 D04 Interim General RF Exposure Guidance v01 SAR-based thresholds are derived based on frequency, power, and separation distance of the RF source. The formula defines the thresholds in general for either available maximum time-averaged power or maximum time-averaged ERP, whichever is greater. If the ERP of a device is not easily determined, such as for a portable device with a small form factor, the applicant may use the available maximum time-averaged power exclusively if the device antenna or radiating structure does not exceed an electrical length of λ/4. As for devices with antennas of length greater than λ/4 where the gain is not well defined, but always less than that of a half-wave dipole (length λ/2), the available maximum time-averaged power generated by the device may be used in place of the maximum time-averaged ERP, where that value is not known. The separation distance is the smallest distance from any part of the antenna or radiating structure for all persons, during operation at the applicable ERP. In the case of mobile or portable devices, the separation distance is from the outer housing of the device where it is closest to the antenna. The SAR-based exemption formula of § 1.1307(b)(3)(i)(B), repeated here as Formula (B.2), applies for single fixed, mobile, and portable RF sources with available maximum time-averaged power or effective radiated power (ERP), whichever is greater, of less than or equal to the threshold Pth (mW). This method shall only be used at separation distances from 0.5 cm to 40 cm and at frequencies from 0.3 GHz to 6 GHz (inclusive). Pth is given by Formula (B.2). Where and f is in GHz, d is the separation distance (cm), and ERP 20cm is per Formula (B.1).
