NOTE -The video processor has battery backup memory and will retain the last selected color balance levels even if the unit is turned OFF or disconnected from the power outlet.

The white balance function adjusts the white balance of each endoscope. Proper white balance requires the use of the white balance adjuster attached to the PENTAX System Cart. Contact your local PENTAX service center for the details if required. 1) Put the distal end of the video endoscope into the white balance adjuster which is supplied with the processor. 2) Watching the monitor, adjust the position of the distal end of the scope in the adjuster so that the circle at the bottom of the white balance adjuster can be recognized on the full screen. ● 3) Press the white balance switch while keeping the scope distal end stationary in the adjuster more than three seconds. If the white balance is established, “WB OK!” is displayed on the screen.

(5) PUMP

To turn the air pump On, press the Air Pump ON/OFF switch. The switch will beep when pressed. Then the LED on the switch will light and the sound of the air pump will be heard. To turn the air pumps OFF, press the ON/OFF switch again. The switch will beep and the LED on the switch will turn OFF. There are two (2) air pump levels, LOW and HIGH. The switches will beep when pressed and the LED on the level switch will light to indicate the selected level. The air pump level will control the pressure of both the air and water delivery. CAUTION - Regardless of the pump level setting selected, avoid delivering too much air to minimize the potential for

pneumatic perforation or barotrauma. 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.
