Q: What are the compatible receivers to AT10II?
A: The standard packed receiver with AT10II is R12DS, which is a 12-channel receiver that supports SBUS and PWM signals synchronously with 2.4G DSSS&FHSS spread spectrum technology.
Besides R12DS, there are also other compatible receivers with different channel quantities available.
R6DS- 6 channels(PWM signal output); 10 channels (SBUS/PPM signal output)
R9DS- 9 channels(PWM signal output); 10 channels (SBUS signal output)
Mini receivers: R6DSM- 10 channels (SBUS/PPM signal output)
R12DSM- 12 channels (SBUS/PPM signal output)
Note
The default channel quantity of AT10II is 12 to work with the standard packed receiver R12DS. When working with the non 12-channel receivers (R6DS,R6DSM,R9DS), the channel quantity of AT10II should be changed as 10.
Long press the Mode key to enter the BASIC MENU -> Rotate the scroll Dial to highlight the SYSTEM option and press Push to enter -> Select the CH-SELECT and change the Number as required.

A: The secondary transmitter's model doesn't need to be the same as that of the primary transmitter. E.G. AT9, AT9S, AT9S Pro, and AT10II can use the trainer function.
Q: Why the trainer function can be activated when connect two transmitters via simulator port.
A: For the trainer function, it needs to connected by a specialized trainer cable, e.g. Radiolink wireless trainer cable(ASIN: B089K4DJRG).
Q: How to adjust the L& H travel of CH5 - CH8 from 75 to 100?
A: When adjusting L or H, need to know which switch control is set for each channel first. For example: if the channel 5 is controlled by a VRB switch, it will need to toggle the VRB switch to adjust the value setting to the L position.

A: PRM-01 is capable of returning model battery voltage in real time.
Q: Can SBUS signal be directly connected to the servo to measure signal?
A: No, SBUS signal can only be tested via oscilloscope or flight controller.
Q: Why there is linkage between CH3 and CH6 of new AT10II/AT9S Pro?
A: The factory default model of AT10II/AT9S Pro is helicopter. CH3 and CH6 is combined in helicopter mode. If the model type is not helicopter, please kindly check if the mix control is turned on.
Q: Which Channel needs to be selected for AT10II/AT9S Pro attitude mode while using DJI flight controller?
A: The default attitude mode of AT10II/AT9S Pro is CH5 for MULTIROTOR. While connecting DJI flight controller, if the receiver output signal is SBUS, change CH7 for ATTITUDE, if receiver output is PWM, choose CH5 for ATTITUDE.
Q:Why the servo range of AT10II/AT10/AT9S Pro/AT9S/AT9 jitters in different ranges? There is an error between the servo range and the actual operation.
A:
1) Calibrate the joystick and restore the factory settings (please change the model before restoration to prevent the parameters in the original model from being reset)
2) If after centering the joystick, there are still 1, 2, 3 servo range, and the trim and END POINT have not been set, please flash the latest firmware.
3)Check whether has changed the joystick with new potentiometer, if has changed the joystick without flashing firmware, please flash the latest firmware.
4)If you still can't get it to work well, then please feel free to let us know. We will help you timely.
Q: Why DJI flight controller can't be armed when using Radiolink AT10II/AT9S Pro?
A: DJI flight controller needs to be calibrated via Mission Planner when change transmitters of different brands.
Q: Why the AT10II/AT10 can't be turned on normally?
A:
1) Check whether the power supply is normal, whether there is insufficient power supply or the battery is inserted backwards.
2) If it can't be turned on after flashing the firmware, please follow the correct steps to flash the firmware again
3)If the power supply is normal and firmware hasn't been flashed, for domestic customers, please return it to the factory for repair; for the foreign customers, please check whether if there is power switch problem. Steps as below:
Short-circuit the two pins in the red box (avoid to connecting the wire in the yellow box), if the transmitter can be turned on after short-circuiting, it means there is a problem on power switch. If you still can't get it to work well, then please feel free to let us know. We will help you timely.
