optical fiber.

fiber CCW (counter-clockwise) with an
8mm wrench as shown on the right.
Slowly pull out the optical fiber.
Immediately place a dust-proof cap on
the fiber to prevent dust from collecting
on the fiber end face.
CAUTION: Never bend the optical
fiber more than the minimum bend
radius of 5.9” (150mm) or you may
damage the fiber.

graphite sheet (placed between the heat sink and the LD module) inside the Control Unit. If the
graphite sheet is cracked or creased, replace it. The graphite sheet is used to transfer heat from
the LD module to the Peltier Cooling device.
12. Install the new LD Module into the Control Unit onto the graphite sheet. Fasten the LD module
with the four hex screws.
