If not, it's a problem with the circuit board, change the external doorbell, it's not worth repairing.
I don't know if the maintenance period of the anti-theft door Ling has passed, if it has not passed, you can arrange someone to repair, and then you can't go online to find some door-to-door service repair stations, but you must be careful to ensure its true reliability. >>>More
It should be that there is frequency interference nearby, can this doorbell adjust the channel, if you can, adjust it. I have encountered some customers who have encountered this kind of problem before, but fortunately, we sell the doorbell with 256 channels to choose from, and you can swap the next channel.
One: Open your security door, in the middle part of the left side of the door, there is a hidden compartment. >>>More
Are you sure the door panel is reversed?
Then you take the [Residential Quality Assurance Certificate] [Residential Instruction Manual] and contact the property management company to find the developer to replace or reinstall the security door. >>>More
It's a bit of both. First replace the battery to see if the battery is dead, and then check whether the circuit is obviously broken. If these two problems are not, you can call the manufacturer's after-sales service phone and ask them to come to solve the problem.
