Interactive Hand-Controller Menus - click on green button to Navigate
This menu lets you select the actual speed for each of the available mount speeds. 

For larger loads, I recommend setting the slew speed to 400 or 600

These speed can be changed from the main screen with the Speed button.

The MOVE- and MOVE+  buttons will decrease or increase Move Speed.

The Guide Speed x5 box is the default guide rate. The guide rate is 10 times the Sidereal rate. Guide rate of 5 is equivalent to 0.5x Sidereal.  Valid selections are 2 through 8. 

To change any of the speeds, touch the appropriate box. You will see a screen that lets you enter the speed using a numeric keypad.
