The T703 has several-user adjustable software variables, which define certain operational parameters.  Usually, 
these variables are automatically set by the instrument’s firmware, but can be manually re-defined using the 
VARS menu.   
The following table lists all variables that are available within the 818 password protected level.  See Appendix 
A2 for a detailed listing of all of the T703 variables that are accessible through the remote interface.
