When was your battery last or ever replaced?

Every 4 to 5yrs is the recommended length

A duff battery can cause many different faults that are not obvious to the untrained eye

Enter your code, press reset (bottom right) key, display should revert to unset. If not your code is not a master code! Ascertain master code and do the above again.
