Subscription Activation Notes
Entering a new authorization code when the unit
already has an active authorization will cancel the
current authorization. This may not be a problem if the
new code overlaps the old code, however, if your new
subscription does not start for some time after the old
subscription, you should not enter the new code until
the old subscription has expired.

begins 9 Jan. New code entered on 9 Jan.
