Is it there a way to stop kalarm error messages from appearing?

http://askubuntu.com – I use kalarm to schedule a lot of terminal actions in an automation process that involves an internet connection, and kalarm is indeed doing great work. But there are certain days in which the error windows are also a lot when the internet fails. I wonder if there is a way to configure kalarm to not show these error messages/windows. I know that I can prevent errors from appearing just after the error shows the windows and I choose not to receive individual error messages. But what I wish is to make kalarm's default behavior to not show error messages anymore. I am using only LTS official (HowTos)
