Mercury - Compuchron Calculator Watch Instructions.

Does anyone have the instructions for the Mercury\Chompuchron calculator watch?
Is there a particular way to enter\exit the calculator mode?

There are 2 ways to enter calc mode. If you press the "C" button you turn on the calculator and clear any previous entries. Pressing the "=" button will also turn on the calculator but retain any entries/operations that were they before it shut down which will occur after 10 seconds of non-use. To turn it off quickly just press the time button.

Thanks for the info
I wasn't sure how to exit the calculator mode, I've not used it for ages and thought that it involved pressing two buttons in sequence - my memory must be fading with age either that or I have too many watches
