AX PRO Issue with AX PRO wireless magnet detectors?

[Harouna]

Hi there, i'm an installer of hikvision products camera and ax pro, im facing an issue now with the ax pro wireless magnet detectors, they are all flashing orange light im not able to enroll them to the central as the orange light is for a low signal, i don't know how to improve the signal to bluel light, kindly look into this and give me some solutions as my client is very upset.
What can I do to change the orange to blue?
Why is it refusing to enroll ?
