• For near focus, rotate the focus ring counter-clockwise (with the LCD screen facing to-

measurement and how the image modes
Thermal MSX , Thermal , and Picture-in-pic-
ture work.
21.5 Autofocusing the infrared camera
21.5.1 General
When autofocusing, the infrared camera can use one of the following focus methods:
• Contrast : The focus is based on maximizing the image contrast.
• Laser : The focus is based on a laser distance measurement. The laser is used when
the camera is autofocusing.
The focus method is configured by a setting. Select ( Settings ) > Device settings >
Focus > Auto focus and then select Contrast or Laser .
Note For large lenses that cover the laser transmitter and receiver, the laser functional-
ity is disabled. This means that the focus method Laser is not available.
21.5.2 Procedure
WARNING
When the camera is set to autofocusing with the laser method ( Settings > Device settings > Focus > Au-
to focus > Laser ), do not point the camera at the face of a person when you use the autofocus function.
The laser beam can cause eye irritation.
To autofocus the infrared camera, push the Autofocus button.
