NOTE
Should debris on the objective lens be difficult to clean, one can temporarily use a higher pump level setting on the video
processor or light source.
While doing so, simultaneously activate the air and suction control valves to minimize air insufflation. After the lens has
been cleared return the air pressure to its original setting for routine use. Regardless of pump level setting selected,
avoid delivering too much air.
Adjustment Switches
You can manually adjust the brightness and color tone of images appearing on the monitor.
1
Press the a or b cc controls for [BRIGHTNESS], [BLUE], and [RED].
• Each press of a or b increases or decreases the brightness or color tone. Each press of a increases the item by one
step and each press of b decreases the item by one step.
• The level of an adjusted item is indicated on the corresponding indicator of the front panel, and the value is displayed
on the monitor. Note that the normal setting is 0 in case you make adjustments.
The exposure control method, measuring method, and brightness adjustment settings are stored in memory even if you
turn off the processor.
White Balance Switch
Adjust the white balance each time you connect a scope to the processor. You can also adjust it whenever you feel that it needs
to be adjusted.
1
Connect the scope to the processor, turn on the processor, and set the exposure control
function to [AUTO].
2
Press the c button to emit light from the distal end of the
scope. (Refer to Figure 4.2)
3
Insert the distal end of the scope into the supplied
white balance device and position it so that the image
of the circle at the bottom of the adjuster fills the
monitor.
4
Hold the distal end of the scope in place without
moving it and press N for at least 2 seconds.
• The [W/B Proceeding] message appears on the monitor and the
white balance is adjusted. After the white balance is set, [W/B OK]
appears on the monitor for about 5 seconds.
