Nikon D80 Manuel D’Utilisation

Choose how long the camera continues to meter exposure when no 
operations are performed (the default setting is 6 s).  Choose a shorter 
meter-off  delay for longer battery life.  Regardless of the setting chosen, 
the exposure meters remain on for ten minutes when the camera is 
powered by an optional  EH-5 AC adapter.

Choose the length of the shutter-release delay in self-timer mode (  
37).  The default setting is 10 s.

Choose how long the camera will wait for a signal from the remote 
before cancelling delayed or quick-response remote modes (   38).  
Choose shorter times for longer battery life.  The default setting is one 
minute.

Select  On  to  delay shutter release until about 0.4 s after the shutter-
release button is pressed, reducing camera shake in situations in which 
the least camera movement could result in blurred photographs (for 
example, microscope photography).  The default option is Off .
