able to dial and have a clear audible click.
b. Follow the instruction of your bore sighter and
install it in the muzzle of your rifle, lining it with the
scope as closely as possible.
c. If applicable, turn on the illumination and set it at
your prefered color and brightness.

J-6 Lockable W/E Operation
2. ZERO LOCKING (The windage/elevation knobs are in the LOCKED
position for a new scope out of the factory.)
i.
Unscrew and remove the cap
of the adjustment knob. Put
the cap away in a safe place.
Gently dial the knob and test if
it is locked. If not, you can skip
section ii.
ii. To Unlock: Locate the two
locking screws as shown on the
right. Use the included small
Allen wrench to unlock both locking screws by turning them
counterclockwise 1/4 revolution.
iii. To Lock: Use the included small Allen wrench to fully lock down
both screws by turning them clockwise. It is recommended that
you gradually lock both screws alternately until they are fully
and evenly locked.
DO NOT over-loosen the locking screws! It may cause the face
cover to fall off if screws are backed out too far. If, by mistake,
the face lid fell off when you were loosening the screws, please
follow instructions below to replace the face cover.
A. Lock both screws down, making sure that they are flush
with the surface.
B. Apply a little loctite or similar adhesive on the flat surface
of the knob. Make sure that no adhesive gets into the
screw holes or onto the screws.
C. Carefully place the face cover back on the knob and align
with the locking holes properly. Firmly press the face
cover to achieve full contact and wait a few seconds to let
the cover adhere to the flat surface of the knob.
WARNING:
1. The Windage and Elevation Adjustment Target Knobs have a
unique Locking Screw design. An Allen wrench is provided with
the scope for adjustment.
ii. Zeroing on a Target
a. Place a target 100 yards away (35 yards for air
gun).
b. Use a steadying device such as a shooting stand
or bipod, set the illumination to your prefer settings,
aim at the center of the target and fire a test group
shot, if safe to do so.
c. If the impact point of the test shot 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. Follow the Point of
Impact (POI) direction on the turret to dial the knob
accordingly.
d. Having adjusted the elevation and windage as
required, fire, if safe to do so, another test group.
Keep adjusting and test firing until the test shot hit
the target center in an acceptable small grouping.
iii. Now the scope should be zeroed. Make sure to replace both
elevation and windage knob caps.
4. ZERO RESETTING
Once your scope is zeroed,
push down both knobs and
make sure they are fully locked.
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. Use the Allen wrench provided to turn both Zero Resetting
Hex Screws on the side of the knob counterclockwise for
1 to 2 turns to dis-engage the W/E knobs. When a knob
is “dis-engaged”, the top cap of the knob can freely spin
without reticle movement. (IMPORTANT: Be gentle with
the screw movement. Do not over extend the rotation. Stop
when the W/E knob is dis-engaged)
ii. 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 your scope before you lock zero and
do zero-reset again.)
iii. Use the Allen wrench to gently tighten down the Zero
Resetting Hex Screws to complete Zero Resetting. (If you
get clicks while tightening the screw, you will need to go
back and re-start from zeroing your scope before you lock
zero and do zero-reset again.)
