CAN’T MAKE SHARP 1. Monitor out of focus. 1. Adjust the focus.
2. Internal splicer error. 2. Service the splicer.
BAD VIEW ANGLE 1. The V-grooves are dirty. 1. Clean the V-grooves.
2. The V-grooves are out of alignment. 2. Service the splicer.
INTERNAL ERROR Splicer needs service. Service the splicer.
