Luna Optics LN-SPRS-4 - Manual (Page 6)

The reticle is also equipped with Windage (Horizontal) Adjustment (16) and
Elevation (Vertical) Adjustment (7). The Windage Adjustment turret is
located on the side of the scope and the Elevation Adjustment turret is on
the top of the scope. To adjust the turrets, remove the covers by turning
them counterclockwise and rotate the turrets click-by-click to the desired
reticle position, while looking into the eyepiece. One click on each turret
represents 1/3” adjustment at 100yds.
ZEROING THE SCOPE:
Attach the LN-SPRS-4 scope securely onto the weapon with help of the
supplied Weapon Mount (14). Set the weapon on a solid base, or bipod.
Remove the Windage and Elevation turrets covers. If sighting during the
day, please remember to keep the protective lens cover (1) on at all times!
If sighting at night or in dark conditions (hours of dusk or dawn) slide the
Protective Lens Cover on top or bottom of the scope and then turn the
scope to the ON position. Do not zero the scope during sunny and
particularly bright light conditions even with cover on.
Set the reticle illumination to a comfortable level. View the position of the
reticle through the rubber eyecup. If the reticle is not in the center of the
image, move it to the center by adjusting (rotating) the scales of horizontal
and/or vertical adjustments (11). Once the reticle is in the center of view,
align the weapon with the target, so that the target is in the middle of the
cross section of the reticle. Make the control shot. Observe the bullet
impact on the target and, if necessary, make additional corrections via
Windage and Elevation adjustment turrets. If necessary, repeat the shots
until you can see the correlation between adjusting the scales and the bullet
impact. Once finished, replace the covers and (if sighting at night) close the
protective lens cover. Do not forget to switch the unit to the OFF position.
USING OPTIONAL REMOTE CONTROL:
Your scope is equipped with capability to utilize optional Remote Control
Pressure Pad. When so equipped, unit can be turned ON/OFF by a pressure
pad connected to the scope via special flexible cord. To connect the
Remote Control Pad, remove the Remote Output Cover (12) by unscrewing
it counterclockwise. Attach the cord paying attention to the exact
connection layout (similar to attaching S-Video cable). Then affix the
Pressure Pad onto the weapon where it can be accessed comfortably with
the palm during operation.
