Echo Filters Updates 

Pearl Echo will automatically update the Echo Filters database each day.  The 

list of Echo Filter categories can be found in Appendix B of this document. 

When you enter the Pearl Echo console, you will be notified when you are 

within two weeks of the expiration of your Category Updates.  You may also 

receive an email notification from Pearl Software.  If your Category Updates 

expire, the effectiveness of Echo Filters will diminish and updates will be 

discontinued. 

Note:  Pearl Echo will perform an outbound transaction on ports 80 and 443 

when updating the Echo Filters database.
