Help! Alarm won't de-activate

[bigtwin]

My bike is fitted with a Datatool Evo Plus and, following a glorious ride out on Sunday, the alarm wont de-activate. The battery in the fob seems to be ok but I have not replaced it yet. Is there some way of 'resetting' the system to bring it back to life?

Thanks in advance for your responses as my acces to the web is limited at the moment.

Is the LED on the fob flashing? If it is, then the battery is most likely ready for a change.
If not, it may need "realigning". Do this by pressing both buttons 'til you get a beep from the alarm.
Finally, have a look HERE (http://www.datatool.co.uk/troubleshooting.asp?ProductID=243) for troubleshooting the alarm.
