Operation of the insertion tube rotation
WARNING
• When rotating the insertion section, the bending section bends to a different
direction against the control section. Before operating the angulation control lever,
make sure to check the position of the projection of the insertion tube rotation ring.
Otherwise, the bending section may bend to a different direction as intended and
patient injury, bleeding, and/or perforation could result.
• Do not turn the insertion tube rotation ring without viewing the endoscopic image.
Patient injury, bleeding, and/or perforation may result.
• Do not turn the insertion tube rotation ring with excessive force while the
UP/DOWN angulation control lever is locked. Patient injury, bleeding, and/or
perforation may result.
CAUTION
• Do not apply excessive force to the insertion tube rotation ring. The equipment may
be damaged.
• Once the insertion tube and the insertion tube rotation ring hits against the stopper,
do not apply excessive additional force. The insertion tube and the ring may be
damaged.
• When rotating the insertion tube rotation ring, do not grip the bending section
and/or the distal end of the endoscope with excessive force. The equipment may
be damaged.
• When rotating the insertion tube rotation ring, do not apply excessive force holding
the insertion section and/or the boot. The equipment may be damaged.
Turn the insertion tube rotation ring as necessary to guide the endoscope for insertion
and observation. Always check the UP indication of the insertion tube rotation ring
that indicates the bending direction against the control section.
