You should have already registered the device at myZyXEL.com (http://
www.myzyxel.com/myzyxel/) and also have either activated the trial license or
standard license (iCard). If your license has expired, you will have to renew it
before updates are allowed.
When scheduling signature updates, you should choose a day and time when your network is
least busy so as to minimize disruption to your network. Your custom signature configurations
are not over-written when you download new signatures.
