here's a trick I recently learned to avoid using the clamp on the buttons
Go to the az or alt ratio menu. Have your pan and tilt speeds already to go. Push the button(s) in the direction you want the head to move and at the same time (while holding the direction buttons) hit 'enter' as if you were going to modify your az or alt ratio numbers. Let go of all the buttons and the head will continue to move until you hit 'enter' again.
up up down down left right left right b-a start!!! remember that one?!
