Still remember with 2 unit Mainboard GSK 928TA which we buy from you? There is one unit mainboard that each installed alarm E88 appears. What is the mainboard we receive broken? Please explanation regarding this.

Only 1 board has this problem, or both have?

Please input UNLK under EDIT mode, E88 means program lock.
