Leapers 30mm 36-color Crossbow Scope (SCP3-1428CRWQ) - Manual (Page 10)

When the adjustment knob is pushed down, the knob
is “locked” and cannot be rotated. This will prevent any
accidental movement to lose zero.
Note: To lock an adjustment knob requires proper gear
engagement internally. Before pressing the knob down to lock,
use minor force to push to get the feel of resistance. If tough to
push down, make very slight rotational adjustment (no clicking)
to locate the right position to press down. DO NOT force the
lock-down.
3. ZEROING
Pull up the windage and elevation adjustment knobs to allow for
adjustment.
i. Zeroing with a Bore Sighter
a. Follow the instructions that came with your bore sighter
and install it in the muzzle of your rifle lining it up with the
scope as close as possible.
b. Pull the windage/elevation knob out for adjustment.
c. Sighting through the scope as though you were going
to shoot and dial the knobs to make adjustment for the
windage or elevation until the crosshair matches the
bore sighter.
d. Push the windage or elevation knob down to lock the
zero position.
e. Remove the bore sighter from the muzzle. You are
ready for zeroing the target.
ii. Zeroing on the Target
a. Place a target 100 yards away (35 yards for air gun).
b. Ideally, use a steadying device such as a shooting stand
or bipod, set the scope at highest magnification, aim at
the center of the target, fire a test shot, if safe to do so.
c. If the impact point of the pellet or bullet is exactly in the
center of the target then the scope is zeroed. If not, you
will need to adjust the reticle using the elevation and/or
windage adjustment as follows:
d. Vertical adjustment (Elevation) – Use your fingers to
turn the adjusting knob as required. One click in either
direction equals approximately 1/2, 1/4 or 1/8 inch at 100
yards depending the model.
e. Horizontal adjustment (Windage) - Use your fingers to
rotate the adjusting knob as required. One click in either
direction equals approximately 1/2, 1/4 or 1/8 inch at 100
yards depending the model.
f. Having adjusted the windage and elevation as required,
fire, if safe to do so, another test shot. Keep adjusting
and test firing until the test shot hit the target center.
g. Now the scope should be zeroed. Make sure to lock
both elevation and windage knobs.
ii. Zeroing on the Target
a. Place a target 100 yards away. (35 yards for airgun scopes)
b. Ideally, use a steadying device such as a bipod or shooting
stand, set the scope at the highest magnification, aim at the
center of the target and fire a test shot, if safe to do so.
c. If the impact point of the pellet or bullet is exactly in the
center of the target then the scope is zeroed. If it is not,
you will need to adjust the reticle using the elevation and/or
windage adjusters as follows:
1 Vertical Adjustment (Elevation) - Use your fingers to
turn the adjusting knob as required. One click in either
direction equals approximately 1/2, 1/4 or 1/8 inch at
100 yards (check exact specifications for your scope).
2 Horizontal Adjustment (Windage) - Use your fingers
to rotate the adjusting knob as required. One click in
either direction equals approximately 1/2, 1/4 or 1/8
inch at 100 yards (check exact specifications for your
scope).
d. Having adjusted the windage and elevation as required, fire,
if safe to do so, another test shot. Keep adjusting and test
firing until the test shot impacts on the center of the
target when the reticle is on the center of the target. This is
vital for accurate shooting.
4. ZERO RESETTING
Once your scope is zeroed, rotate the Zero Locking Ring to lock
zero. The “0” marking may not be facing you at the original center
position now. Optionally, you can use the following steps to Reset
Zero by rotating the “0” marking to the center positions:
i. Ensure zero is “locked”.
ii. Use the Allen wrench to turn the Zero Resetting Hex
Screw by 180-360 degrees to dis-engage the W/E knobs.
(IMPORTANT: Be gentle with the screw movement. Do not
over extend the rotation. Stop when meeting resistance in
the rotation)
iii. When the W/E knob is dis-engaged, rotating the knob will
not produce any clicking sound and will not affect zero.
You can re-position the “0” marking to the center position.
(If you get clicks when rotating the W/E knob, the knob
was not properly dis-engaged. You need to go back and
re-start from zeroing the scope before you lock zero and do
zero-reset again.)
iv. Before tightening the Zero Resetting Hex Screw, turn the
Zero Locking Ring counter-clockwise by 40-70 degrees to
un-lock zero.
v. Be careful to keep the W/E knob still now that it is un-
locked. Use the Allen wrench to gently tighten down the
Zero Resetting Hex Screw to complete Zero Resetting. (If
you get clicks while tightening the screw, you will need to
go back and re-start from zeroing the scope before you
lock zero and do zero-reset again.)
vi. IMPORTANT: Rotate the Locking Ring clockwise to lock
zero immediately.
Important Note: When turning the Zero Resetting Screw loose
to dis-engage W/E, zero has to be “locked”. When tightening the
Zero Resetting Screw to engage W/E, zero cannot be locked.
Scope damage may occur if the steps are not followed.
J-2 TF2+ Tool Free W/E Operation
1. The Windage and Elevation Adjustment Knobs have a unique
2-stage Tool-free design. The windage/elevation knobs are in the
“locked” mode on a new scope out of the factory. Pulling the knobs
upward allows for windage/elevation adjustment.
2. ZERO LOCKING (The windage/elevation knobs are in the
LOCKED position for a new scope out of the factory.)
