MAJ-2306 INSTRUCTION MANUAL

Ch.8

The image (illumination) is 
dark or too bright.

The brightness is adjusted improperly.

Set optimum brightness by referring to 
“

Adjusting the NBI brightness” on 

page 27.

The communication cable is not 
connected to the LED light source.

Connect the communication cable by 
referring to the instruction manual for 
the LED light source.

The light guide cable connected to the 
LED light source is disconnected 
halfway from the light guide terminal.

Connect the light guide cable 
completely by referring to the 
instruction manual for the LED light 
source.

An extraneous light from a shadowless 
lamp, etc. is incident to the observed 
region.

Adjust the extraneous light so that it is 
not incident to the observed region.

Image is noisy.

The AGC is applied at a high level.

When the image brightness becomes 
insufficient in observation of a distant 
view, etc., the AGC is applied strongly, 
making the image noisy. If this 
happens, reducing the observation 
distance can increase the image 
brightness and decrease noise.
