 b.	Slowly raise the CONTROL GAIN to 2-3 for low current beams, around 5 for high current beams.  The system is now controlling in GVM mode.
-c.	Make fine adjustments to the TERMINAL VOLTAGE Dial to reach exactly the desired GVM value.
+c.	Make fine adjustments to the TERMINAL VOLTAGE Dial to reach exactly the desired GVM value.  Very fine adjustments to the terminal voltage can be made using the FINE control located coaxial to the BIAS CURRENT control with a full range of 1.5 KV.
 d.	Switch OVERVOLTAGE PROTECTION to ENABLE.

  b. If not already visible on the control room computer screen, start the appropriate software GUI's using the "Restart" button for "analyzer, switcher, swinger, or tweaker" magnets.
- c. In the "Switcher_hz422" and "Analyzer_hz422" GUI windows, magnet beam deflection (left/right) is indicated on the "Magnet Current" line indicated as beam "left or right". The polarity can be toggled using the "Polarity" button located to the right of the "Lock" button.  When the "Polarity" button is pressed, the magnet current will automatically be set to zero and the polarity will reverse.The "Swinger_hz422" and "Tweaker" have no polarity reversal button.
