11.5.2 Procedure
Follow this procedure:
1. Do one of the following:
• For far focus, rotate the focus ring clockwise (with the LCD screen facing toward
you).
• For near focus, rotate the focus ring counter-clockwise (with the LCD screen facing
toward you).
Note Do not touch the lens surface when you adjust the infrared camera focus manually.
If this happens, clean the lens according to the instructions in 26.2 Infrared lens, page 103.
Note It is very important to adjust the focus correctly. Incorrect focus adjustment affects
how the image modes Thermal MSX, Thermal, and Picture-in-picture work. It also affects
the temperature measurement.
