Operation Manual
Some of the Crossfire II riflescope models use an image focus/parallax 
adjustment which provides maximum image sharpness and eliminates 
parallax error. Lower power models do not use image focus/parallax 
adjustments and are pre-focused at a distance of 100 yards.
Image Focus and Parallax Correction
• Be sure the reticle is correctly focused (see Reticle Focus on page 4). 
• Rotate the adjustable objective until numbers match the distance you 
are shooting. Align yardage number to the indicator arrow on scope body.
• Check for proper setting by looking through the scope to verify image 
sharpness and, at the same time, look for reticle shift while moving 
your head back and forth. The setting is correct if there is no apparent 
movement between the reticle and target while your head is moving back 
and forth. If there is apparent movement, adjust the focus knob slightly 
until the movement is eliminated.
Using image focus/parallax correction:
When properly set, the target image should be sharp and crisp.

Parallax is a phenomenon that results when the target 
image does not quite fall on the same optical plane as the 
reticle within the scope. When the shooter’s eye is not 
precisely centered in the eyepiece, there can be apparent 
movement of the target in relation to the reticle, which 
can cause a small shift in the point of aim. Parallax error 
is most problematic for precision shooters using high 
magnification.
