WHITE BALANCE CONTROL
SELECTION SWITCH
Prior to every procedure the camera, endoscope and light source
system should be white balanced to assure accurate tissue color.
To automatically adjust the white balance, point the distal tip of the
endoscope (with camera attached to the instrument eyepiece and
instrument coupled to the light box with lamp illuminated) at a
white object, such as a piece of paper or a white wall, while holding
the distal tip of the instrument one inch from the surface.
Follow the procedure in the camera’s operating instructions regard-
ing Auto White Balance Control (AWC) and White Balance
Setting. Welch Allyn recommends that the camera operate in the
AWC mode.
CAMERA CABLE CONNECTOR
This connector is found on the front panel of the Camera
Control Unit and is used for connection of the camera.
Warning: Connecting and disconnecting the camera cable
must be done after turning OFF the power ON/OFF switch.
