WARNING
• If the endoscopic image seems to be dark in an optical-digital observation mode,
change to the normal observation mode. The examination might not be performed
safely.
CAUTION
• Do not press the observation mode button when the video system center is OFF (or
is not connected with the light source) and a light guide cable incompatible with
PDD is used. Pressing the button activates the PDD mode (“PDD” indicator light
up) and may cause insufficient brightness for examination.
In this case, press the observation mode button again to cancel the observation
mode.
• For PDD observation, use only the light guide cable and rigid endoscope
compatible with PDD. Otherwise, an improper image may be obtained.
NOTE
Set the brightness of the examination light to the minimum necessary to perform
the procedure safely. If the endoscope is used for a prolonged period at or near
maximum light intensity, vapor like smoke may be observed in the endoscopic
image. This is caused by the evaporation of organic material (remaining blood,
moisture of stool etc.) due to heat generated by the light guide near the light guide
lens. If this vapor continues to interfere with the examination, remove the
endoscope, wipe the distal end of the endoscope with a lint-free cloth moistened
with 70% ethyl or isopropyl alcohol, reinsert the endoscope, and continue the
examination.
