Interactive Hand-Controller Menus - click on green button to Navigate
Note that the Web limits are set for left and right side, while the hand controller uses East and West.  If using the hand controller, follow these steps. (The hand controller method only works correctly on August 16 or later firmware.)
  1. Turn off tracking by placing the mount into Terrestrial mode.  Menu->Track->Terrestrial
  2. Move the RA using the Left-Right buttons to the Eastern Limit.  Loosen the clutch in Dec. Make sure you can spin the telescope 360 degrees in Dec without it hitting the mount.  Use the Menu->Mount->Limits->"Set Limits Here" button, to set the Eastern Limit.
  3. Hit the ENT button to return to the previous menu. 


Note: Safety Limits may not take effect until you power down and back up. That has been my experience, however the writer of the firmware says they take effect when set.
