There are two X/Y beam movement functions - "Manual Alignment" and
"Designated Position". When "Manual Alignment" is selected, it is pos-
sible to move the X/Y beam through manual alignment operation while
observing the recognized image. "Designated Position" makes it pos-
sible to move the X/Y beam to the designated position by using numeri-
cal values.
• Manual Alignment
(1) When the [beam Axis Move] button is pressed, the following sheet
appears.

(2) Press the [High] or the [Low] button to specify the speed of the X/Y
beam movement.
The direction of the X/Y beam movement must also be specified by
pressing one of the "Direction" buttons (Up, Right, Down, and Left
Arrows).
(3) Press the [ENABLE] button on the operation panel in two seconds
after the [ON] button (entitled "MOVE") to move the X/Y beam to the
recognition test position (Fig. 2F18).
When the [ENABLE] button on the operation panel is pressed in
2 seconds after the manual alignment operation is performed
and the [P.E.C. Recog. Test] and [ON] (entitled "MOVE") but-
tons are pressed, a P.E.C. recognition test is made and the
