À không tìm ra manual nhưng tìm ra cách learnID rồi:
1. Press and hold [M] for 3 sec
2. use [+] or [-] until you are in learn mode S-4
3. Press [ok]
4. Toggle [+] or [-] to select the desire tire (1-5), press [ok]
the tire number should blink once per second
5. Deflate and inflate the tire at least 4psi (I found 5-7psi works best)
until the tire icon blink twice a sceond, once learn, the ID will stop blinking and beep for 5 seconds.
