11.6.1.  Full Setup Passcode  
Setting a passcode for Full Setup restricts access to Full Setup.   
11.6.2.  Safe Setup Passcode  
Setting a passcode for Safe Setup restricts access to Safe Setup functions.  In 
addition, front panel functions can be configured to prompt for a Safe Setup 
passcode before operating.  Refer to 12.1.4 KEY.LOC (Key Function Access 
Control) on page 56 for more information.  
11.6.3.  Operator Passcode  
The operator passcode is used to protect access to instrument functions available 
from the front panel keypad.  Refer to 12.1.4 KEY.LOC (Key Function Access 
Control) on page 56 for more information on how to add security to operator 
functions. 
The operator generally needs to enter the Operator Passcode only once to gain 
access to multiple functions.  To lock the instrument again press the ‘.’ key for two 
seconds (LOCK function).     
11.6.4.  Setup Lock-Out 
If an attempt is made to enter Full or Safe Setup using an incorrect passcode, the 
instrument will respond with the message ENTRY DENIED and then the user will be 
returned to normal operating mode.   
No more than three failed attempts can made to access Full/Safe Setup before the 
instrument blocks access completely.  The instrument must be turned off and on 
again before further attempts can be made.
