Cleaning the distal end
Cleaning the optical adapter
Dirt or water droplets on the objective lens of the distal end
Grasping the rigid portion of the distal end, use a clean, soft piece of gauze or a cotton swab to
wipe off the dirt or water. You could also use the brush to brush away dirt and water.
Best results may be obtained using a commercially available absolute ethanol or isopropyl alcohol.
Dirt or water on the surface of the optical adapter and/or the objective lens in the optical adapter
Use a piece of clean, soft gauze or cotton swab to wipe off dirt and water. You could also use the
brush to brush away dirt and water.
Cleaning dirt from the optical adapter outer surface while attached to the distal end
Grasping the rigid portion of the distal end, wipe the optical adapter. Best results may be obtained
using a commercially available absolute ethanol or isopropyl alcohol.
Dirt on the threads of the screws of the optical adapter.
Moisten a cotton swab with a commercially available absolute ethanol
or isopropyl alcohol and continue cleaning until doing so leaves no dirt
on the cotton swab. Clean in the sequence (1), (2), (3) as shown in the
nearby illustration. Spin the cotton swab while cleaning.
Also, for thorough cleaning, turn the optical adapter while doing (2) and
(3).
Build up of dirt on the optical adapter positioning surface or threads of the distal end
Use the brush provided with the cleaning kit to brush away built up dirt.
Note that insufficient cleaning can result in a loss of water tightness between the optical adapter
and the distal end.
●
Do not clean the optical adapter under running water.
Otherwise, the optical adapter might be damaged.
