NORMAL STABILIZED OPERATION - Continued
To illuminate the reticle, momentarily depress the reticle illumination
switch (6) located on the top rear center of the M25 Stabilized
Binocular. The switch can be stepped through six levels of increasing
brightness and then returns to normal (non-illuminated). This is
beneficial during low light level situations (dusk, dawn, overcast) when
the reticle may be difficult to see against the background.
