Motor is running. 
 
Low Level, Low Gain – Background is 
generally the same shade because 
Gain is Low.  All Hot surfaces show as 
White.  There is some distinction on 
cooler surfaces – Tires, Grill Guard, 
and snow bank. 
 
Medium Level, Low Gain – Raising the 
Level setting now shows more detail 
on the hot surfaces.  Cooler 
background objects look like they are 
at the same temperature. 
 
High Level, Low Gain – The 
background objects now all look like 
they are at the same temperature.  
The Level setting now is set for the 
temperature of the hot engine, and 
shows detail around the temperature 
of the hot surfaces close to the engine 
compartment.
