This section describes in more detail the steps carried out in the Configuration Wizard.  For manual 
configuration of the logger, it is recommended that the user carries out the following tasks in order:

logger which are needed, exit the configuration wizard at  this point, download the  data, and then 
return to the configuration wizard.
