Dirhmun thlennak le ralrin peknak thlennak luhternak:

Dial switch K1 cu "ON" lei ah a um tikah, chuahmi dirhmun cu luhnak dirhmun he aa ralchanh.
Dial switch K1 cu "OFF" lei ah a um tikah, a chuakmi dirhmun cu a luhnak dirhmun he aa tlak.
Dial switch K2 cu "ON" lei ah a um tikah, circuit nih a langhtermi meiinn sen LFD ralrin peknak riantuannak kha a thim.
Dial switch K3 le K4 nih a tu ahcun zeihmanh an chuahpi lo.
