Packaging Details:
- G.W.: 0.3kg

Receiver:
1. Wiring:
1.1. Servo wiring
R: To roll servo (This pin can also be plugged into a 5V power supply)
P: To 270° pitch servo
Y: To 270° yaw servo

1.2. Servo selection:
- Voltage: 5V
- Angle: 270°
- Signal PWM: 500-2500us

1.3. LED Status:
- PW: Power supply indicator light. It is red
- MOD: Status indicator light. It is green

2. Frequency Matching:
Step 1: Press and hold the button while powering the receiver, and the green light will flash.
Step 2: Press and hold the button while powering the transmitter. At this time the green light will flash.
Step 3: The green light of the receiver is off, indicating that the frequency is matched, and TX and RX modules will be restarted, and the servos can also operate at this time.
Attention: *If the servos do not move after binding frequency, press the button once to set the neutral position of servos and the servos can be operated.

3. Change the direction of servos:
After the power is turned on, press and hold the button, and the direction of the pitch servo and the yaw servo will be changed once. If you find that the direction of the servos is wrong, press and hold the button again until the servo direction is correct. Adjust it up to 4 times to make the servo direction correct.

4. Adjust the neutral position of servo:
Step 1: Press the button once and the green light will flash.
Step 2: Adjust the direction of the transmitter until the servo position reaches the specified position.
Step 3: Press the button once, the green light will be off, and the setting will be completed at this time.



Transmitter:
1. Angle reset:
When the camera angle deviates greatly from the head tracking angle, you can press the button once to reset the angle.

2. Binding frequency:
Refer to the receiver frequency matching operation above.

3. Calibrate compass:
- Press the button twice to enter compass calibration mode.
- At this point, the LED 'S' red light will flash, which means that the compass is being calibrated. At this point it needs horizontal and vertical rotation modes, and then wait for the LED 'S' to turn off, that is, the calibration is complete.

4. Charge:
- The maximum charging current is about 400mA. Please make sure that someone is present when it is being charged to ensure that it is safe to charge. The maximum charging voltage is 5V. When fully charged, it can be used continuously for about 5 hours.
- The LED 'C' will turn off when it is fully charged. The LED 'C' will light up during charging.
- Note: It is forbidden to charge while using!
