l have this problem : alarm 1 and 2 displays on the screen are not working anymore after they were blinking lower and lower weeks after weeks... they were displaying enough each time l removed the power line from sector (during minutes, then seconds.. enough to know if it's on/off), but l can't see them anymore.. so l don't know if alarm 1 and 2 are "on" or "off".. wich is sad because every other functions and displays are working perfectly.
