Before inserting or withdrawing the endoscope, set the insertion tube to an
appropriate level of flexibility by turning the flexibility adjustment ring as
required (see Figure 4.4).

2.
When changing the insertion tube's flexibility during a procedure, turn the
flexibility adjustment ring slowly, and closely monitor the position of the
flexibility marks, the endoscopic image and the patient's condition.
Whenever the endoscope is not in use, set the insertion tube
to its most-flexible condition. Otherwise, endoscope damage
may result.
• If the sterile water level in the water container is too low, then
air, not water, will be supplied. In this case, turn the airflow
regulator on the light source OFF and add sterile water to the
water container until it reaches the specified water level.
• If air/water feeding does not stop, turn the airflow regulator
on the light source OFF and replace the air/water valve with a
new one.
• Before using a syringe to inject liquid through the biopsy
valve, detach the valve's cap from the main body. Then insert
the syringe straight into the valve and inject the liquid. If the
cap is not detached and/or the syringe is not inserted
straight, the biopsy valve could be damaged, which could
reduce the efficacy of the endoscope's suction system, and
may leak or spray patient debris or fluids, posing an
infection-control risk.
