4.5 White balance adjustment
This adjustment procedure is used to display the correct image color on the
monitor. There are two white balance adjustments for the normal observation
and the NBI observation. Be sure to always adjust the white balance in the
following cases:
• Before observation.
• After exchange of the light source.
• When any abnormality can be seen on the color of the image even if
white balance adjustment has been completed.
• When adjusting the white balance of the endoscope to be
used in the sterilized zone, do not use the white cap (MH-
155) as described in this part, but use a white object such as
a piece of gauze without bringing it in contact with the
endoscope. Contact of the endoscope with a non-sterilized
object may result in cross-contamination.
• Make sure that the endoscope and white cap (MH-155) are
clean before adjusting the white balance. Otherwise, cross-
contamination may result.
• Always control the color tone and/or enhancement of the
image appropriately before observation. Setting an
inappropriate color tone or enhancement condition may
result in overlooking or wrong diagnosis.
