3) Next, Select "Optical Adjust".  Some systems may require a Passcode be entered, the passcode is "0219"

4) Next select the "Auto" button.  After selecting the instrument will do an auto adjustment to the optics system, please do not turn the instrument or attempt to exit the software while it is performing this function.

5)  Verfiy that the Sig and Ref signals are near 4.0 +/- .25.  If they are not, it may require a manual adjustment in which case please contact AGS Technical Support.
