Removing the Spliced Fiber
1. Raise both heater clamps before removing the fiber.
2. Open the windshield. A tension test (200 g) is performed on the fibers.
3. Buzzer beeps once when the tension test is completed.
4. Remove the spliced fiber, pulling slightly so that the fiber is taut.
Handle the spliced fiber carefully. Do not twist the fiber.
!
CAUTION
Do not attempt to load fibers while the S178 Ver.2 fusion splicer is
resetting. Load the fibers only after the reset operation is complete and
the READY screen is displayed.
