When this error code appaers on the display it means you cannot connect to wifi anymore. The reason is that the wifi board is broken or the wifi connect wire is cut off.


This is a manufacturing defect and cannot be repaired. Please contact your point of purchase for warranty claim.


This solution is suitable for Model AC-5670.
