The screen color can be adjusted by using the WHITE BALANCE function.
1. Please direct the arrow to point to "WHITE BAL" on the SETUP menu by adjusting the
switch to UP or DOWN direction.
2. Please select the mode you would like to operate by adjusting the switch to LEFT or
RIGHT direction.
Please select one of the 3 modes below:
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).
AWC (Auto White Balance Control): Press the SET button while the camera is
directed at a piece of white paper to get the optimum state under the present

select ATW or AWC first. Then change to manual adjustment mode and press the SET
button. Set the suitable color temperature, and increase or decrease the red and blue
