No problem. 11 digits. Please refer to other people's explanations for registration. "For the power, after resetting, ① keep pressing the OFF button on the remote control currently in use, and a small beep! beep beep beep sound will continue to sound from the side of the antenna. ② Press and hold the OFF button on the remote control you want to register until it stops, and the sound will sound again. ③ Press and hold the OFF button on the remote control currently in use, and the sound will stop, and registration is complete." Please refer to the above, as it was written by someone else. I cannot provide any further explanation. Since it's S34, please use an 11-digit one.
