6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Transmitter not powering on | Low or dead batteries; incorrect battery installation. | Replace batteries; ensure correct polarity. |
| No response from model | Transmitter and receiver not bound; receiver not powered; incorrect wiring. | Perform binding procedure; check receiver power supply; verify all connections. |
| Limited channels available | Transmitter set to 6-channel mode; receiver is 6-channel. | If using a 10-channel receiver, activate 10 channels in the transmitter menu. Ensure your receiver supports 10 channels. |
| Interference during operation | Other 2.4GHz devices nearby; environmental factors. | Operate in an open area away from other wireless devices. The AFHDS 2A system is designed to minimize interference. |
