Deleting iCal Notebook Calibration reminders

[yourdream]

Does anyone know how to get rid of notebook calibration reminders? I am talking about the ones that Apple has on their page (webcal://www.apple.ca/batteries/images/notebook_icalreminder.ics)

Select the event in iCal and hit the delete key.

Select the event in iCal and hit the delete key.

It says that I can not delete the event because it is a read-only calendar.

That's a subscription calendar. Select the entire subscription in the left-pane of the iCal window, and delete it. You can do this using the right-hand click context windor, and it will remove the subscription and all events tied to it.
