NIce, I love my chronos too! It sits at work, beside a set up chessboard just waiting to play.
The manual though, bah! Once I had watched the video it was all good. Set the first five presets for the games you like to play and your off :-)
My only disappointment is that I wanted a yellow one, but ended up getting a black one. Oh well, black is the new black and all that.
Here's a video on setting the Chronos II chess clock.
There is always a lively controversy about just how difficult the Chronos is to set. It usually goes something like this:
Point: Wow, I'm having a hard time setting the Chronos for three time periods and a Bernstein delay.
Counterpoint: What? Are you an airhead? If you can't set the Chronos, you don't deserve calling yourself a chess player. You disgust me !
My opinion is this. The Chronos and associated user manual are not exactly jumping-off-the-shelf user friendly, but the clock is just so awesome I don't care. If my house was burning down, my Chronos clock would be the first thing I'd save.
