The Park/Unpark Settings group box contains controls to park and unpark the mount.  The driver supports the 3 standard Astro-Physics park positions and one custom Alt/Az position.

Unpark

Click to perform an unpark operation. You should always unpark from Last Parked if you have not moved your mount between imaging sessions.

However, if you are setting up your mount you may want to unpark from one of the 3 standard mount park positions (see your mount's manual for descriptions/pictures of the three positions).

If you have a mount with fixed park positions, like the Mach 2, the only choice will be to unpark from Last Parked because the mount always knows it's position, even when the clutches are loosened and the scope moved.

Park

Click this button to start a park operation. The mount will slew to the position selected in the Park To drop-down list box.

Slew East Before Parking

Sometimes when imaging a southerly object across the meridian the telescope may start to pass under the north side of the mount. If this happens when trying to park to AP Park Position 3 the scope could hit the pier as the mount tries to orient the scope north.

To prevent this from happening select this option and set the number of hours to whatever you think is necessary. 6 hours equals one quarter rotation of the mount’s RA axis. When a park operation starts the mount will "unwind" that number of hours if and only if the telescope OTA is on the West side of the pier.

Park Alt
Park Az

This is a user defined park position. You must slew to the position you would like to set as the Park Position and click Set Alt/Az Park Position. This can be especially handy for parking the mount with the scope aimed at a "flats screen."

Set Alt/Az Park Position

Clicking sets the user-defined Alt/Az Park position to the mount's current Alt/Az coordinates.
