This angle of the front lens allows the light generated by the LED projector inside the unit to be reflected back through the rear lens. The reflected light becomes the “dot’ or aiming reference that the user sees when a green dot sight is switched on.

Installation

1. The mount bracket is adaptable to standard Picatinny rails.
2. With our patented nonlinear cam clamping system, no tools are required for mounting. Push the locking button, lift up handle to loosen the locking bar. To mount the sight on your rail, push the lever down & the locking button will automatically engage. The installation is complete, (see fig 4)

3. Initial installation: When first installing the sight, the clamp may be too tight such that the handle cannot be locked. You must adjust the clamp bolt for a proper fit.

1) There is one Torx socket at the end of clamp adjusting bolt on the side of the mount. (See Fig 5) Before installation, loosen the bolt to loosen the clamp using the included Torx wrench.
2) Open the cam clamp lever. Slide the sight into rail and close the clamp lever, ensuring the sight is on the rail.
3) Tighten the clamp adjusting bolt using the Torx wrench. This will tighten the clamp to the rail to moderate degree. Try to open and close the clamp handle, adjusting the clamp bolt so it is neither too tight nor too loose. Torque should be 5-10 inch/pounds.

and low brightness levels.

2) Manual Mode:
a) Press down the “+”button for 3 seconds to enter into the Manual mode.

c) Switching back to auto mode: A single press of the “+” button for 3 seconds will switch the sight to auto mode.
d) Holding down the “-” button for will cycle between the two reticle choices

4. Sleep time mode:
1) Please note that your green dot will automatically enter into sleep mode after 10 minutes of no movement
2) The sight will instantaneously wake up and turn on with any motion detection to last saved setting.
3) The default sleep timer setting is 10 min, but can be adjusted.
i. Press and hold the “+” button for 10 seconds to enter time adjustment mode. There are 4 options: 10 min, 1h, 12h, or the sleep mode is disabled.

Zero Setting

1. The sight has been pre zeroed, but some additional adjustment may be necessary as all firearms are unique
2. The elevation adjustment screw is at top rear end of the sight, the windage adjustment screw is on the left side of the housing. Adjustments can be made by inserting the included wrench into the adjustment screw slots and twisting, (see Fig7),
3. To move the point of impact up or right, twist counter-clockwise. To move the point of impact down or left, twist clockwise. Each click will result in a 1/2 MOA movement.
4. The maximum adjustment range is +40MOA from Center. Caution: Don’t try to over rotate the knobs, if you feel the knobs cannot be rotated further, you are at the adjustment limit.
   Further adjustment may damage the sight. If the required zero range is beyond the limits, consider adding extra spacer between the device and the mount rail to expand the adjusting range limits.
