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)


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.

* All RadioLink transmitters are not open sourced and can only bind to receivers developed by RadioLink.







Q: How to check AT10II RSSI value?

A: Power on the transmitter and receiver with both antenna as parallel and straight and within the distance of 30cm.









Long press the Mode key to enter the BASIC MENU -> Toggle the CURSOR to highlight the TELEMETRY option and press Push to enter

Then check the RSSI value. Range between 0~-30dBM is normal when the distance between transmitter and receiver is around 30cm, and if the value gets closer to 0, the signal is stronger. If the value is between -30~-90, signal is not good and the control distance would be limited.







Q: Why can’t bind the AT10II/AT10 with R12DS/R12DSM/R9DS/R6DS/ R6DSM?

A:  1) check transmit mode is on or off, if it is off, the green light is off.

2) check the receiver is power on or not, whether the binding procedures are correct.

3)  If still can’t bind it after check the above situation, please kindly return them to the factory fro maintenance.







Q:Why the servo range of AT10II/AT10/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.









Q:Why the screen gets blank when power on the AT10II/AT10/AT9S/AT9?

A:Check whether the firmware was flashed before it’s blank screen. If yes, reflash the newest firmware, if it is still blank, please kindly contact our after-sales personnel.

A:Check whether the battery voltage is too low to supply enough power to the transmitter, thus caused blank screen.









Q: Why the AT10II/AT10/AT9S 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 still can’t turned on, replace the board.





Power switch parameterItem number SS-22F32








Q:Is it necessary to use the same model transmitter as secondary TX if using the trainer function of AT9/ AT9S/AT10/AT10II?

A: The secondary transmitter’s model doesn’t need to be the same as that of primary transmitter. E.G. AT9S and AT9, AT9S and AT10II are compatible for trainer function.







Q: Why the trainer function can be activated when connect two transmitters via stimulator cable?

A: For the trainer function, it needs to connected by specialized trainer cable, e.g. Radiolink wireless trainer cable.








Q:How to use AT10II?

A: Please click below link to check the tutorial video









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.








Q: What information can the PRM-01 of AT10II return?

A:  PRM-01 is capable of returning model battery voltage in real time.








Q: Why the battery display indicates only half of power even if the transmitter is fully charged?

A: The battery display is related to the alarm voltage set by the remote control. The lower the alarm voltage is, the more power can be used and the fuller the battery display is. ( Tips: Please set the low voltage alarm value according to the battery you use. For example, if you are using a 3S battery, the low voltage alarm value should be set to 3.7V * 3 = 11.1V)







Q: How to restore to factory settings?

A: Long press the MODE key to enter the BASIC MENU -> Rotate the scroll Dial to highlight the MODE TYPE option, choose the mode type needs to restore to factory settings,  and press Push to enter -> Select RESET: Execute, Press PUSH key again as required, then show out “ Please waiting” and DEE sound. The factory setting is successfully restored after Dee sound disappears.






Q: Will the parameters of different model types set before be cleared or modified once the firmware flashed/upgraded?

A: No. The firmware upgrade won't change any personalized parameters already set.






Q: Can one transmitter controls two receivers?

A: Yes, it can controls two receivers at the same time, like CH1 to CH2 connect to R12DS, CH5 to CH9 connect to R6DS.







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: Are all Radiolink receivers compatible with digital servos?

A: Yes, all Radiolink receivers support digital servos and analog servo.









Q: Why there is linkage between CH3 and CH6 of new AT10II?

A: The factory default model of AT10II 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 attitude mode while using DJI flight controller?

A: The default attitude mode of AT10II 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  jitters when connecting DJI A2 and A3 flight controller?

A: The servo range of DJI A2 and A3 is between 0-20000, while that of AT10II is 0-2000, the difference is 10 times. Therefore, it is normal when servo range jitters within a dozen range during setting parameters on DJI flight controllers.







Q: Why DJI flight controller can’t be armed when using Radiolink AT10II?

A:  DJI flight controller needs to be calibrated via Mission Planner when change transmitters of different brands.
