Disarm as if you're going to start the bike. Turn on the ignition and then press the arm button on the fob and hold it until it beeps at you. You can then turn the ignition off and disconnect the battery. You will hear a beep every 15 seconds or so for the first day (ish) even after you take the battery out.
To put back to normal after putting battery in, just treat it like normal disarming/starting.
cheers guys, but want to do it without the beeping, bike in the garage on an alley and dont really want to advertise the fact its there! Got a solution of using the monnie battery while on charge, so looks like I'll have to do that.
Sure - as far as I know the only thing you can do is replace the battery with another while you do this. The beeping does stop, after a while. I had my battery off for a few days recently and it was not beeping the following day.
