FACTORY DEFAULT 
The  DT3900 allows  you reset to factory  defaults  via the setting section in 
the menu. 
It  is  important that  you  do  not  perform  this  function  unless  absolutely 
Necessary. 
Perform  this  function  if  you  have  moved  to  another  location  and  need  to  
rescan  the  set  top  or  the  set  top  is  performing  erratically  and  may  need 
factory settings to rectify the problem.
