4.   FOCUS: You can focus the camera by three methods, Autofocus, Electric or Manual. 
 To Auto adjust push and release the center of the Focus Button. If this method does not give you a perfect 
focus use one of the following methods to further adjust. 
 Electric (motor driven) focus is achieved by push the Focus Button to the left or right.  
 Manually adjust focus by turning the IR Focus Ring on the camera lens either clockwise or counterclockwise. 
5.   AUTO ADJUST: To allow the camera to adjust the temperature scale’s Level and Span, first 
push the Mode Button to show the mode selector menu. Make sure the “Camera” mode icon is 
selected (Fig. 1). Push in on the joystick to return to a live image. 
 Push the Auto/Manual button so that “Auto” appears in the upper right corner of the viewing 
screen. The camera will now continuously auto correct the Level and Span settings.  
6.   MANUAL ADJUST: (Preferred Mode) As above, make sure that the camera is in “Camera” mode.   
 Push the Auto/Manual button so that “Manual” appears in the upper right corner of the viewing screen. 
  The temperature scale Span can now be manually increased or decreased by pushing the Joystick left or 
right. 
  The temperature scale Level can now be manually raised or lowered by pushing the Joystick up or down. 
  A one time auto adjust can be performed (while still remaining in manual mode) by momentarily pressing in
