W (White Balance) Button
The W button activates the white-balance function or the light/zoom function.
The white balance function is used to correct slight color differences that exist
between different light sources or endoscopes.
• Press the W button for more than one second to activate the white-
balance function.
• Press the W button for less than one second to increase the light or
zoom level. The camera console can be set to "light" mode or "zoom"
mode using the Options submenu of the Configuration Menu. In
"zoom" mode, each W button press will raise the light level in four
steps. In "light" mode, each press will raise the zoom level in four
steps. When either mode has reached its maximum, pressing the W
button again will cycle the level back to the lowest setting.
Perform the white balance procedure before every surgical procedure.
Note Ensure that a scope and light source are attached to the camera,
and that the camera, light source and monitor are powered on
before adjusting the white balance.
1. Point the scope at several stacked 4 × 4 white gauze pads, a white
laparoscopic sponge, or any clean white surface.
2. Look at the monitor and make sure that no glare is visible off of the
white surface.
3. Press and hold the W button until "WHITE BALANCE" begins flashing
on the video monitor.
4. Continue pointing the scope at the white surface until the video monitor
indicates that white balance is "complete. " The video picture may change
color. If you cannot achieve an acceptable white balance, refer to the
"Troubleshooting" section of this manual.
Up and Down Buttons
The up and down buttons work together to increase or decrease the light/zoom
level.
The camera console can be set to "light" mode or "zoom" mode using the Options
submenu of the Configuration Menu. In "light" mode, pressing the arrow buttons
will raise or lower the automatic-shutter light-level setting in 29 steps. In "zoom"
mode, pressing the arrow buttons will raise or lower the zoom level in 8 steps.
Press the arrow button once to adjust the light level by one step or hold down the
button for a quicker transition.
