MK 188 how to start

Hello.
Is somebody who can tell me how to start a single shot pulse with this kit ?
where is the input ?
Thanks you a lot.

I think that when you apply power to the MK188 the timing cycle starts automatically.
If you would like something like this with an external trigger you may want to look at the VM141.
