MANUAL ADJUST (Level and Span):

 

To manually adjust Level and Span, press the On/Off/Menu, then 

highlight Level/Span and highlight L/S? and push the On/Off/Menu button. You will notice the top and bottom 
number will be highlighted and can now be adjusted. To adjust the span, use the ►◄ buttons. Using the left button 
will narrow the span and the right button expands the span. To adjust level, use the ▲▼ buttons. The up button 
raises the level to higher temperatures and the down button lowers the level to lower temperatures. When the 
camera is in Manual Mode, there will be an L/S displayed in the upper left corner of the LCD screen. 

Note:

 the highlighting and ability to change level and span will time out in a few seconds of inactivity. To reactive/re-

highlight them, merely push the A button. Then use the directional arrows to adjust Level and Span.
