1. While pressing two buttons of [x] and [DISPLAY] simultane-
ously and connect the AC power cord.
2. It enters the panel and key test mode, and all segments on the
liquid crystal display light up.
3. Each time a button is pressed, the segments on the liquid crys-
tal display corresponding to each button disappear.
4. When all buttons are pressed, all segments on the liquid crystal
display disappear.
