You can specify MASK 1 and 2 simultaneously.

If <BACKLIGHT> is set to <BLC>, the MASK AREA function is not available.

￿EXT : The interface to an external alarm enables an automatic switch between DAY and NIGHT mode.

If you set <DAY/NIGHT> to EXT, and alarm #1 to NO/NC in ALARM SET- ALARM IN SET, the alarm can be used for an input signal in EXT mode of <DAY/NIGHT>.

If an alarm signal occurs, the mode will switch to NIGHT.

MIf <DAY/NIGHT> is set to EXT, ALARM1 in ALARM OUT SET, and ALARM1 in ALARM SET-AUTO SET are not available.

If you use an infrared light source while in AUTO mode, this may cause a failure in AUTO SWITCH or AUTO FOCUS.

WHITE BAL

If you need to adjust the color according to the ambient illumination, you can use the <WHITE BAL> function.

For selecting and saving each menu item, refer to “How to use the keyboard controller”. (page 20)

Illumination is generally referred to as color temperature, which is represented in a measurement of kelvin (K). Color temperatures for ordinary lighting are as follows:

English

In the <WHITE BAL> menu, you can set a mode for correcting the <WHITE BAL>.

-ATW1,2 : If you set the <WHITE BAL> menu to <ATW1> or <ATW2> mode, this will monitor the change of the color temperature to correct the <WHITE BAL> as needed.

The following color temperature ranges are assured in individual modes:

ATW1 : 2500K ~ 9300K (￿1)

ATW2 : 2000K ~ 10000K

￿1 : With <ATW1> mode active in a color temperature environment ranging beyond between 2500K and 9300K, a proper white balance value may not be produced; if this is the case, you are recommended to use <ATW2> mode.

￿2 : With <ATW2> mode active in a mostly single color environment, the display color and the actual one may differ; so select a mode as appropriate to your color temperature environment.
