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.
The round one switches it on and off, and if you push it with the ignition switched on it goes into service mode - bleeps every 30 seconds to tell you it's not arming or protecting anything.
The triangle is ferry mode, which switches off the motion sensor while still keeping the alarm/immobiliser armed for changes in current drain and other tampering.
