MAJ-2306 INSTRUCTION MANUAL
Ch.6
CAUTION
• Do not approach a cord connected to the high-frequency electrosurgical equipment
to this instrument and the ancillary equipment combined with it. Otherwise,
malfunction may be caused during the high-frequency output.
This section describes the method of switching the observation mode to NBI. For other operating
procedures, refer to the instruction manuals for the surgical microscope and LED light source.
WARNING
The information obtained through NBI is merely reference information. Be sure to
perform a comprehensive observation of all required regions by also using the WLI
observation.
CAUTION
• If the image is felt dark during NBI observation, adjust the NBI brightness or set the
NBI AGC to set the NBI AGC MAX gain to higher by referring to Chapter 4,
“Function Setup”. If the image is still dark, use the WLI imaging because the normal
NBI observation may be impossible.
• If any irregularity is felt during NBI observation, immediately return to the WLI
mode. Otherwise, the normal NBI imaging may be impossible.
• Always set the power switch of the LED light source to “ (ON)” before turning the
surgical microscope ON. If the LED light source is turned ON after the surgical
microscope, malfunction may result.
• Do not apply strong extraneous light, including that from a shadowless lamp, to the
observed region. Otherwise, accurate observation may become impossible.
NOTE
• The illumination light is extinguished temporarily during the observation mode
switching.
• Switch to NBI observation mode only when the surgical microscope is in WLI
mode.
• If the spare lamp selector lever of the LED light source is set to “SPARE LAMP”,
NBI observation is not available.
• Some switches and buttons cannot be operated for a few seconds in which the
observation mode is switched over.
