I had the same issue and used the spine of a book to ensure simultaneous pressing of all 6 buttons. It took alot of attempts but eventually worked. Mine is quite old so for anyone struggling, just keep trying!

Nothing worked for me, but I kept trying...about the 5th time of attempting to press all 6 buttons at once, it worked! So keep trying!

I had the same problem and "Christine" is right. Press the second and third button and then reset using the + and -. Hope this helps!

If your Rangemaster is like mine then you need to press 2nd and 3rd buttons simultaneously and press + or - button to adjust time not forgetting it is a 24 hour clock.
