Press and pull to take out the battery. 5 Operating Instructions 6 Operation and control �.� Boot program 1 -3- 2 45 3 ★★Before taking off, please be sure to put the drone on a horizontal surface and calibrate it to ensure that the drone flies smoothly after takeoff. ★★When the drone is hit or deflected after a collision during flight,the same method can be used to correct the gyroscope. �.� Speed Selection �. Insert the battery into the battery compartment firstly, then turn on the power switch (the drone's LED light flashes), and put the drone on a solid surface. 3.2.4Ghz frequency matching between controller and drone Push up the left joystick ( controlerl makes a beep, controller indicator light � flashes red, and drone LED lights flash) and then push it down (the controlerl makes a "beep"sound, the controller indicator light turns solid red), that means �.�Ghz frequency signal is matched between drone and controller. 4. Gyroscope calibration Push the left and right joysticks as per above picture at the same time and release them at the same time. The drone blades will rotate at a low speed. The LED lights on the drone will stop flashing and become solid, means successful calibration and the motors will start. Press the upper left button to select different speed. Each time it is pressed, the Drone will switch to a corresponding speed (as shown on the right) with indication "beep" sound. �. One beep is low-speed speed control, the drone is controlled at a speed of ��% of full speed. �. Two beeps are for medium speed control, the drone is controlled at a speed of ��% of full speed. �. Three beeps are for high speed control, the drone is controlled at a speed of ���% of full speed. �. Push the left joystick upward or press the one-key takeoff button; the drone taking off. �. Press on the power switch of the remote controller (the remote controller makes a "beep" sound, the remote control indicator light Red and flashes, and the drone LED lights flash, too). �.� Basic action operation methods -4- For beginners, it is recommended to operate the joystick slowly to avoid damaging the drone due to excessive movements. When the left joystick (throttle) is pushed up or down, the aircraft will fly up or down accordingly. When the left joystick (throttle) is pushed left or right, the aircraft will turnleft or right accordingly.

Shenzhen Tongzhou Testing Co.,Ltd FCC ID: 2AFDJFX-41 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).
