2Use the joystick lever (xy) to select [SENSE UP] and use the lever (vw) to select magnification power of electronic sensitivity.

Available settings: OFF, X2, X4, X8, X16, X32

3Use the joystick lever (xy) to select [LEVEL] and use the lever (vw) to adjust the iris level.

Available settings: 0 (dark) - 100 (bright)

☞After completing setting, use the lever to move the cursor to [MENU] and select “BACK” or “END”.

•Electronic sensitivity boosting (SENSE UP) automatically lengthens the CCD exposure time in dark situations. Accordingly, moving target objects may cause conspicuous afterimages, blurs and white spots.

•When electronic sensitivity boosting (SENSE UP) is enabled, the electronic shutter function will not work.

•When the Day/Night function is set to “AUTO”, electronic sensitivity boosting (SENSE UP) works only while black and white image is displayed.

bManual iris (MANU)

When the [IRIS] is set to “MANU”, lens aperture can be set manually.

Because activating the electronic iris disables the auto iris function, you need to set appropriate lens aperture using the following procedure.

1Use the joystick lever (xy) to select [IRIS], use the lever (vw) to select “MANU”, and press the [ENTER] button.

The IRIS SETTING screen appears.

2Use the joystick lever (xy) to select [EI] and use the lever (vw) to select “ON”.

The electronic iris function controls both the AGC circuit and shutter speed to change exposure value.

3Use the joystick lever (xy) to select [IRIS STOP] and use the lever (vw) to adjust the aperture opening value.

Selecting the value changes the lens aperture opening. Available settings: 1 (close, darker) - 17 (open, brighter)

4Use the joystick lever (xy) to select [LEVEL] and use the lever (vw) to adjust the iris level.

Available settings: 0 (video level is darker) - 100 (video level is brighter)

☞After completing setting, use the lever to move the cursor to [MENU] and select “BACK” or “END”.

Notes on setting electronic iris (EI):

•If the iris views an unusually bright image, it can cause a smear that cannot be corrected by adjusting the light entering through the lens. In this case, arrange the physical angle of lighting in a way that will prevent on-screen smearing.

•If there is a fluorescent lighting in the camera location, flickering of the target object may occur. Changing fluorescent lighting to incandescent lighting will prevent the flickering.

•When the electronic iris (EI) is activated, the electronic shutter (SHUTTER) setting cannot be made.
