EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• If the biopsy valve is left uncapped during the procedure,
debris or fluids could leak or spray from it, posing an
infection-control risk. When the valve is uncapped, place a
piece of sterile gauze over it to prevent leakage.
If the endoscope is cold, dew condensation may form on the
surface of the objective lens, and the endoscopic image may
appear cloudy. In this case, increase the temperature of the
sterile water in the water container to between 40 – 50°C
(104 – 122°F) and then use the endoscope.
Air/water feeding
1. Cover the air/water valve’s hole to feed air from the air/water nozzle at the
distal end (see Figure 4.5).
2. Depress the air/water valve to feed water onto the objective lens (see Figure
4.5).
