Was the walkie-talkie repaired by this property or by yourself?

I think it's a walkie-talkie for visiting.

Normal belongs to ancillary facilities, just like the cat's eye of a security door.

During the warranty period, the developer of the property company will repair it.

If it passes, you need to find someone to repair it yourself. You can report it to the property management to see if there is any maintenance in this area. It is estimated that the salary will be paid.

I hope to give you a reference.
