3 Pre-observation/pre-operation preparation and inspection
●
When inspecting the insertion tube, be sure to hold it at a point behind the angulation section. Otherwise,
the angulation section may be damaged.
●
Also be sure to check the inspection items after using the instrument.
3.3 Pre-operation/post-operation inspections
Inspection
location
Item
If abnormality is
discovered
Overall
Any dirt, sand, or other foreign matter on the control unit,
insertion tube, battery cover, video connector cap, AC
adapter connector cap?
See "7 Storage
and maintenance"
(P. 68).
Any cracks, scratches, or other defects to the control
unit, insertion tube, battery cover, video connector cap,
AC adapter connector cap?
Replacement
required.
Contact Olympus.
Any irregularities such as damage to or deformation of
the exterior material, buttons, joysticks, or levers?
Irregularities such as cuts or kinks in the universal ca-
ble?
Insertion
tube,
angulation
section,
distal end
Any looseness in materials other than the angulation
section?
Replacement
required.
Contact Olympus.
Any dirt or water droplets on the objective lens of the
distal end?
Continued use in this condition creates the risk of
damage to the optical adapter and/or distal end.
See "7 Storage
and maintenance"
(P. 68).
Any build up of dirt on the optical adapter positioning
surface or threads of the distal end?
Any distal end deformation or looseness, or unusual
connecting screw wear?
Never use the instrument while there is any looseness
on the distal end. Doing so creates the risk of loose
parts falling into the inspection object.
O-ring
Is the O-ring missing, broken, etc.?
An O-ring that is misaligned or broken can allow water
or other liquid to get into the joint between the distal
end and optical adapter, creating the risk of malfunc-
tion and damage.
CAUTION
