Directions for use

Caution
• Users as well as the assisting personnel should always wear protective equipment (e.g., gloves,
goggles, masks, medical gowns, etc.) to minimize the risk of infection, as the patient’s body fluids
may be dispersed into the environment from endoscope components such as the instrument
channel inlet and the suction control valve.
• Do NOT look directly at the light emitted from the endoscope or direct it at the eyes of other
individuals, as the intense light may cause eye injuries.
• Set the brightness to the minimum necessary. Maintain an appropriate distance between the
distal end of the endoscope and the mucosa in order to avoid prolonged illumination of the
mucosa. The temperature at the distal end of the endoscope may exceed 41°C and even reach
50°C due to the light emitted from it. This may result in mucosal injury to the patient.
• Do NOT use the endoscope when adherence of patient materials (e.g., blood, other body fluids)
is suspected, as this will darken the image. This will also cause the temperature of the distal tip
to increase, which might lead to mucosal injury to the patient.
• Use the minimum pressure necessary for suctioning. Do NOT suction from the mucosa for a
prolonged period of time. Doing so may result in patient injury.
• Do NOT excessively pull the umbilical cord or give shocks such as objects or people hitting the
scope connector. Doing so could cause temporary disappearance of endoscopic images. If any
abnormality occurs in the images, connect the scope connector again to the video processor.
Note
• Prior to a procedure, remove as much debris as possible from the observation area in order to
obtain a clear image.
• The objective lens may be cleaned during a procedure by performing air/ water feeding and
suctioning either alternately or simultaneously.
