Perform the vision test.
Press the [Test] button and check to see if the pattern is correctly recognized. Repeat
this test several times. When no error occurs, the pattern data is appropriate.
If an error occurs, check whether "Search Area" of the Vision parameters is appropri-
ate. If the search area is too large so that other marks are located within the search
area, then reduce the search area. Conversely, if the search area is too small, then
enlarge the search area.

3.1.2 Using the data for pattern matching
Pattern matching can be used in the same way as the fiducial marks. In this case, enter
the mark No. registered as the pattern in the Mark 1 and Mark 2 columns on the [Board] -
[Fiducial] tab screen. (The figure below shows an example when using pattern matching
as PCB fiducial marks.)
Set mark No. registered as pattern in
"Mark 1" and Mark 2" columns.
Set to "Execute".

4.1 Halfway Continue function
Pressing the [Halfway Continue] button on the Setup screen opens the Halfway Continue
dialog box as shown below. Even after resetting the mounting data, the Halfway Continue
function allows you to load that mounting data to mount components again at a specific
block or mount point. Note that the Halfway Continue function can be used just for the
first PCB, with routine mounting operation beginning from the next PCB.
