3. Binding the Receiver
To establish communication between the transmitter and receiver (R12DS), follow the binding procedure. Power on the transmitter and ensure the throttle stick is at its lowest position. If the signal tower icon is not present on the screen, binding is required. Press and hold the binding button on the R12DS receiver for 1 second until the light stops blinking, and the signal tower appears on the transmitter screen.

4. Telemetry Module Connection (PRM-01)
For real-time voltage monitoring, connect the PRM-01 module. Connect one end of the PRM-01 module to the telemetry port of the R12DS receiver. Connect the other end of the PRM-01 module to your airplane's battery. Once connected, the battery voltage will appear on the AT10II screen.

Maintenance
To ensure the longevity and optimal performance of your Radiolink AT10II transmitter, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the transmitter's exterior. Avoid using harsh chemicals or solvents.
- Storage: Store the transmitter in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Remove batteries if storing for extended periods to prevent leakage.
- Gimbal Care: Keep the gimbals free from dust and debris. Avoid applying excessive force to the sticks.
- Antenna: Handle the antenna with care to prevent damage. Ensure it is properly extended during operation for optimal signal.
Troubleshooting Common Issues
If you encounter issues with your Radiolink AT10II, refer to the following common troubleshooting steps:
- No Power: Check battery installation and ensure batteries are fully charged. Verify the battery type is compatible (8 AA or 2S-4S LiPo).
- No Signal/Binding Issues: Ensure the receiver is correctly bound to the transmitter. Re-perform the binding procedure if necessary. Check for any obstructions or excessive distance between the transmitter and receiver.
- Unresponsive Controls: Verify that the receiver is powered and properly connected to the servos/ESCs. Check the servo travel display on the transmitter to ensure channels are responding correctly.
- Telemetry Data Missing: Ensure the PRM-01 (or PRM-03) module is correctly connected to both the receiver and the battery. Check module connections for looseness.
- Alarms: Pay attention to RSSI and low voltage alarms. Address the underlying issue (e.g., move closer, charge battery) immediately.
