If it's anything like my Datatool Veto then it self-arms after 20 secs. My key-fob has a triangle button which puts the alarm into maintenence mode (ie: you can move her around). I get a sort of sickly squeak when using the triangle and a solid beep (off) or two (on) from the round one.
Many congrats on the bike. For ten years it's been the best looking bike on the planet, and I'd doubt it'll be eclipsed in the next ten.
Cheers,
Ali
