and DOWN buttons.
2. Please select the mode you would like to operate by pressing the LEFT or RIGHT button.
Please select one of the 3 modes below:
Ö ATW (Auto Tracking White Balance): This mode can be used within the color
temperature range from 2,500°K to 8,300°K (eg, fluorescent light, outdoor,
sodium vapor lamp or inside tunnels).
Ö AWC (Auto White Balance Control): Press the SETUP button while the camera is
directed at a piece of white paper to get the optimum state under the present

object.
NOTE:
Under the following conditions, the WHITE BALANCE function may not operate well. In
such cases, please select the AWC mode.
○
1 When the object’s surroundings have a high color temperature.
○
2 When the object’s surroundings are dark.
○
3 If the camera faces a fluorescent light directly or is installed in a place where the
illumination changes constantly, the WHITE BALANCE function may become unstable.
