⚠️ Important Notes
🔧 Binding Procedure
| 1. Power Off TX |
Ensure transmitter is turned off |
| 2. Connect Bind Plug |
Insert bind plug into receiver BIND/BAT port |
| 3. Power Receiver |
Connect battery/power to receiver (LED flashes) |
| 4. Power On TX |
Turn on transmitter (hold bind button if needed) |
| 5. LED Solid |
Receiver LED becomes solid = binding successful |
| 6. Remove Bind Plug |
Disconnect bind plug, power cycle receiver |
| 7. Test Control |
Verify all channels respond correctly |
🔍 Troubleshooting
| No Binding |
Check bind plug position, verify TX powered on |
| Weak Signal |
Extend RX antenna, avoid metal enclosures |
| Servo Jitter |
Check power supply, ensure clean 5V to receiver |
| Wrong Direction |
Use servo reverse function in TX menu |
| Short Battery Life |
Fully charge TX battery, replace if old |
| LCD Dim/Blank |
Charge battery, check backlight setting |
| Lost Connection |
Re-bind TX and RX, check antenna orientation |

⚠️ Important: Requires binding before first use. Charge transmitter battery 4-5 hours before use. PWM output only (not compatible with SBUS/PPM without adapter). Receiver needs 4-8.4V power (5V typical from BEC). Set failsafe to cut throttle for safety. Range test before each flight. Keep receiver antenna vertical for best signal. No telemetry – basic radio only. Compatible with KK2.1.5, CC3D, APM, and other PWM-input flight controllers. Not compatible with high-end FPV racing protocols (requires PWM receiver input on FC).
