The splicer must be re-
paired at the service cen-
ter.
Level too low
LID receives no
light.
Check that you have
inserted the fiber
into the LID. If the
fault still occurs
select
Manual fiber
adjustment
from
the menu and check
that a minimum level
of 0.5 is displayed
when a continuous
fiber is inserted.
Clean the LID system and
ensure there is sufficient
index-matching fluid on the
input and output areas. If
the LID level is still not
high enough with a con-
tinuous fiber, the fiber is
not LID-compatible. In this
event, you can either re-
move the color from the
fiber which is inserted in
the LID or use one of the
video programs.

ual fiber positioning (with
or without LID).
