Each code is made up of two series of flashes.
The long flashes indicate the 'tens' digits.
The short flashes indicate the 'ones' digits.
A long pause separates each code sequence.
Code Format Diagram shows code No. 12.
A series of repeating short pulses indicates No codes in memory
If nolongflashes are observed then the code is a straight count of short flashes. i.e. 4 flashes = code 4.
