18. BRIGHTNESS ADJUSTMENT

> In the menu item “brightness setting”, press the Zoom button to

change the four brightness levels from 1 to 4 and back to 1.

19. WARM / COLD WHITE DISPLAY

Here you can choose between two options for displaying images.

This option is not available in the false color mode.

20. VIDEO OUT

> Turn on the analog video recording function in the main menu.

The video output icon will appear in the lower-right corner of the

image. The analog video can be output to an external monitor

with the supplied video transmission cable via the MCX interface.

21. SENSOR CALIBRATION MODE

> Short press the Zoom button to change between S (shutter) and

B (background) calibration mode.

During use, the image will deteriorate gradually because of

changing background temperature of the sensor. This needs to be

equalized by periodically calibrating the sensor.

In S mode, calibration is done automatically via an internal shutter

that makes a faint clicking noise. The calibration can also be done

manually by pressing the zoom and photo buttons simultaneous-

ly during viewing if a deterioration in image quality is detected

during use.

In B mode, no automatic calibration is done. Pressing the zoom

and photo buttons simultaneously during viewing performs a

manual shutterless calibration. During calibration in B mode, the

lens cover needs to be closed (this is also being prompted by an

icon appearing in the display). Otherwise, an image of the scene

viewed during calibration will be imparted on the sensor. This can

be corrected by a proper calibration.

22. PICTURE IN PICTURE PIP

When the PIP function is turned on, a small

window appears at the top center of the

screen, showing a 2x enlargement of the

center area of the image.

23. DIGITAL COMPASS

> Turn on the digital compass function in the main menu.

It will be displayed in the middle top of the screen, indicating the

current direction.
