Movement to memorized positions
Memorized positions
Automatic rotation can be used for movement to one of three memorized positions as shown in the table
below.
When a new position is memorized, the same numeric value is set for positive and negative movement.
For example, if an exposure is made which sets the last-used +Oblique angle to +50°, the last-used -
Oblique angle is set to -50°.
How to reach a memorized position
•
To rotate the Arm to one of these positions, press the button shown for more than one second and
then release it.
•
An automatic rotation movement started by pressing one of these buttons can be stopped at any time
by pressing any of the buttons located on the Arm or one of the footswitches on the floor, or by touch-
ing the compression paddle.
