Attaching the optical adapter
1
Positioning the optical adapter with the distal end so they are directly opposite
each other, carefully insert the optical adapter into the distal end.
6-mm type
4-mm type
●
Be sure to attach the O-ring to the insertion tube’s distal end before using the optical adapter.
Water getting into the area where the insertion tube and optical adapter join might cause malfunction or
damage. Also note that an optical adapter by itself is not watertight.
●
If an optical adapter cannot be mounted or removed because the nut will not turn, stop using it.
Contact Olympus.
●
Never use the instrument while dirt or water is present in the optical adapter
Water tightness between the optical adapter and the distal end may be lost, or the optical adapter or the
distal end may be damaged.
