Start prefusion
Once the fibers are rough-aligned, you press the FUSE but-
ton. During prefusion the fibers are cleaned by low level
heating.
Inspect fibers

This is your last chance to check the fibers before splicing, so
you should switch between the two viewing angles by press-
ing VIEW button, looking for dust or any other imperfections.
If dust remains, or you see any other problems you should
abort the splicing procedure and re-prepare the fibers. For
examples of problems you should watch out for, see p 13.

Now that you have assured yourself that the fibers are clean
and of good quality, you can fine-tune their alignment. In
order to set the gap, you use the and buttons, bringing
the fibers as close together as possible without overlap.
You then briefly press the GAP button. The resulting gap
should be as narrow as possible, but still wide enough to
allow for free movement of the fibers up and down (see
illustration on next page).
Using the and buttons you can now fine-tune the
alignment of the outer fiber edges, making sure that the two
fibers line up straight across the screen.
If at any point, you feel the view is not clear, use the and
buttons to improve the focus.
Do not forget to adjust the fiber alignment from both camera
angles, which you can toggle between by pressing VIEW.

After prefusion is complete the splicer sends new messages

BASIC OPERATION - Manual mode splicing
The last movement before you set the gap must be to
move the fibers inwards (closer together).
After you have set the gap, do not press the and
buttons.
