2ATOY-RT62TRUE WIRELESS EARBUDS

TRUE WIRELESS EARBUDS USER GUIDE TURNING ON YOUR EARBUDS METHOD 1: Remove your earbuds from the charging case. METHOD 2: If the earbuds are not inside the charging case or are turned off, touch and hold the RIGHT or LEFT earbud for 4 seconds until the blue LEDs flicker and you hear battery percentage. TURNING OFF YOUR EARBUDS METHOD 1: Place your earbuds back in the charging case. METHOD 2: Touch and hold your earbuds for 5 seconds until you hear “Power OFF.” BLUETOOTH PAIRING INSTRUCTIONS FIRST: Remove both earbuds from the charging case. They will auto-pair to each other. SECOND: Keep the earbuds within 10m of your smart device (for Bluetooth pairing only). Enable your device’s Bluetooth function from its Settings menu. Select “RT62” from the Bluetooth device list to pair the earbuds to your device. Once paired, you will hear “Device Connected.” Your RT62 earbuds are now ready to use! SINGLE EARBUD USAGE Each earbud can be used independently. CALLING/MUSIC ANSWER/END CALLS Touch the RIGHT or LEFT earbud 2 times. REJECTING A CALL Touch and hold the RIGHT or LEFT earbud for 2 seconds or until you hear a prompt sound. PLAY/PAUSE Touch the RIGHT or LEFT earbud 2 times. NEXT SONG Touch the RIGHT earbud 3 times. REWIND/PREVIOUS SONG Touch the LEFT earbud 3 times. VOICE ASSISTANT Touch and hold the RIGHT or LEFT earbud for 2 seconds or until you hear a prompt sound to active the Voice Assistant/Siri function. This function may not work for all devices. CHARGING THE RT62 Make sure to fully charge the earbuds prior to the first use. CHARGING THE CASE Plug the standard USB-C charging cable into the port on the case, and connect the USB head to a USB power source, such as an AC wall adapter or a computer. The LED indicator will flash green while the case is charging. Once the case is fully charged, the LED will illuminate solid green. CHARGING THE EARBUDS When the earbuds are low in power, you will hear “Battery Low.” Place the earbuds into their respective slots in the charging case. They will automatically begin to charge. The LEDs will turn solid red while charging. The LED on the bottom of the case will turn white then turn off after 4 seconds. Once the earbuds are fully charged, the LEDs on the earbuds will turn off.

Shenzhen Tongzhou Testing Co.,Ltd FCC ID: 2ATOY-RT62 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).
