with the impact point of the pellet or bullet from the rifle. Before zeroing
the scope, read the following adjustment knob instructions carefully.
Note:
For crossbow scopes with PRO 5-STEP and PRO 4-STEP Reticle,
please also refer to Section D for more reticle-specific zeroing details.

The Windage and
Elevation Adjustment
Target Knobs have a
unique Resetting Screw
design. An Allen wrench is
provided with the scope for
adjustment.

ZERO LOCKING (The windage/elevation knobs are in the
LOCKED position for a new scope out of the factory.)
Finger tighten the Zero Locking Ring by rotating clockwise
by 40 - 70 degrees. Do not over-tighten. When the Zero Locking
Ring is tightened, the windage or elevation adjustment knob
is “locked”. The knob will not rotate, preventing any accidental
movement to lose zero.
3.
ZEROING
Un-lock the adjustment knobs by turning the Zero Locking Ring
counter clockwise by 40 - 70 degrees. Now, Windage/Elevation
adjustment knobs can be rotated.

shoot and dial the knobs to make adjustment for the windage
or elevation until the crosshair matches the bore sighter.

position.
