How to engage record mode

[dragons]

Hello!
I would like to see instructions on putting ALP in record mode on a sticky, so it is easily accessible, I am fairly certain I was hit by a Poliscan today I would like to record it next to to send back to see if the Poliscan firmware is any different to see how it compares to other places.
I have seen it somewhere round the forum but can't seem to find it right now.
