Could somebody please clarify how the timing offset is supposed to work?
I have pressed the 5 minute button and it shows the correct intervals as 5,10,15 etc. I press the offset to read 2 minutes thinking that this would change the timings to 7,12,17. It doesn't and it stays as 5,10,15 etc. Pressing OK and coming back into the screen shows the offset back as 0 minutes with 5,10,15 timings. Am I missing something?
