New Rev counter

So, fed up with the Ducati rev. counter bouncing between 0-10K rpm, I though I would add a cheap alternative, just so I know roughly where I am. I purchased this off ebay, honestly the Chinese will rule the world - 5 quid and free postage for a rev. counter. Anyway, the first thing you notice when you get it out of the package is that there doesn't appear to be a way to switch it off, so it's built as a disposable rev. counter lasting as long as the lithium battery lasts! Setting it up was easy, although there are different modes for 1 spark, 2 sparks per revolution etc... honestly didn't seem to make much difference. The other thing you notice is that it has quite a big latency, so it won't do to look at fast changes, but will still be useful when cruising at a fixed engine speed. Anyway, for a fiver what did you expect!

Here is what the Chinese manufacturer said to do :

If you want to turm off it.
You need press the S2 ,when LED show '05'.Press the 02 together untill the LED show '00'.After few seconds.The item will turn off.

Just a simple process then! haha...
