I have just aquired a Nocon timer without instructions, the only info I've discovered on the web, which I think originated from a site by Rod Ashford, seem to belong to a different model.
The timer has a five digit display, 20 buttons marked in f-stops from -1 to +4 and buttons marked: reset, calc, enter, increase, focus, initial.
I seem to have figured out that it works as follows:
Enter a time into the display, press enter and then when initial is pressed the timer will switch on the enlarger for the entered time. Focus is an over-ride switch which just turns on the enlarger. By entering an initial "base" time and then activating any combination of the f-stop buttons, the timer will switch the enlarger on for up to each "minus" time and the base time, by using the initial button, thereafter counting up to each over-exposure, using the increase button. If a base time is entered and then one of the f-stop times is entered, followed by calc, the calculated new time can be displayed. Reset seems to get me back to the original base time when pressed after the other functions have been used. In order to reset the base time, the unit needs to be turned off and on again. I don't know if any other functions can be achieved and various combinations of buttons still elude me or produce an error display.
If any one else can help by confirming this is how it's supposed to work or if there are features I am missing, I would be grateful.
