4. Operating Instructions

4.1 Powering On/Off

• To power on, press and hold the power button until the LED indicator lights up.
• To power off, press and hold the power button until the LED indicator turns off.

4.2 Binding to a Receiver

The binding procedure varies depending on the receiver and protocol (Frsky D16, Frsky D8, Futaba S-FHSS). Generally, you will need to put your receiver into binding mode and then activate the binding sequence on the LiteRadio 2 SE. Refer to your drone's flight controller or receiver manual for specific binding instructions. The LiteRadio 2 SE typically has a dedicated button or stick combination for initiating binding mode.

4.3 Gimbal Calibration

Regular calibration of the gimbals ensures precise control. The LiteRadio system allows for easy joystick calibration. Consult the official BETAFPV support resources for detailed steps on how to perform gimbal calibration.

4.4 Low Voltage Warning

When the internal battery voltage drops below 3.5V, the LED indicator on the transmitter will flash blue, signaling that it's time to recharge the unit.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the transmitter. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the transmitter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is charged to approximately 50-60% to prolong its lifespan.
• Firmware Updates: Periodically check the BETAFPV website for firmware updates. Keeping the firmware updated can improve performance and add new features.

6. Troubleshooting

• Transmitter not powering on: Ensure the battery is sufficiently charged. Connect to a USB Type-C power source and check if the charging LED activates.
• Unable to bind to receiver:
  • Verify that both the transmitter and receiver are in binding mode.
  • Confirm that the transmitter's protocol (Frsky D16, D8, or Futaba S-FHSS) matches the receiver's protocol.
  • Ensure the transmitter and receiver are within close proximity during the binding process.
• Poor control response/drift:
  • Perform gimbal calibration as described in the operating instructions or the official BETAFPV support page.
  • Check for any physical obstructions or damage to the gimbals.
• Not recognized by FPV simulator:
  • Ensure the USB Type-C cable is securely connected to both the transmitter and the PC.
  • Check your PC's device manager to confirm the transmitter is recognized as a joystick or game controller.
  • Verify that your FPV simulator software is correctly configured to use the LiteRadio 2 SE as an input device.
