Correct position of the device
When zeroing the optic, the first thing you will need to do ismake sure the optic is mounted securely to the rail and with the proper eye relief that you will need based on your preference. So long as you are not using an aftermarket mount, the bolt should be secured slightly tighter than hand tight. The rating is around 15 inch pounds. Do not over-tighten as this could cause damage to the bolt in the mount.
Start off the process with a target up close around 10 yards. Placing a small piece of aluminum foil on the target, allows for the heat collection and easier to sight in. I make sure the foil is angle slightly towards the sky to make sure it reflects a different temperature as the rest of the target. If you have a 'hold over' target that shows the offset for your preferred zero distance at 10 yards that can help speed up the process.
Preparation for zeroing
Start by powering the unit on. Hold the joystick in the up position until the main menu pops up. Use the joystick to scroll to the 'Zeroing profile' option. Press up or down to set the optic on a particular profile. There are multiple profiles to be used for separate calibers or separate zero distances. Once you have selected the profile you wish to use scroll right once to the 'zeroing' option.
Press up to select the zeroing option. The screen will then show a 'back' option and an option to add a distance. This icon looks like a paper with a plus sign on it. Scroll to the paper with the plus sign and press up to add a distance. It will then allow you to add a distance by pressing up or down on the joystick to scroll through the numbers. Once you have entered the distance you plan to zero at you can scroll to the icon that looks like a paper with a check sign on it. Press up on that icon to save the distance.
At this point you have created a zero distance under one of the profiles. The purpose of this is to remind you what distance you are setting the profile to. You should be at the initial zeroing screen at this point which includes a 'back' icon, the zero distance you entered, and the 'add zero distance' icon as well. Scroll to the distance you just created and press up to set the zero.
You should now be on the actual zeroing screen. It should say 'press mid button to freeze' at the top of the screen. It should also display an X and Y coordinate value on the screen. The default is '0.0' for both. Being that this is a digital adjustment we are going to bring the reticle to the point of impact as opposed to a mechanical adjustment optic where we make adjustments to bring the impact to the reticle. As an example, if your impact is low and left we would need to move the reticle low and left. The coordinates will reflect this value. This is opposite of a normal daytime scope where you would need to move the impact up and right and your turret adjustments would in turn be up and right.
Each 'click' (or short press of the joystick) to the right or left along the 'X' axis will adjust for windage. The same if true for the 'Y' axis as it will adjust for elevation. Each click will adjust for two pixels in terms of elevation and four pixels in terms of windage. This is reflected on the coordinate values as 0.4 for elevation and .8 for windage. Each 'click' of elevation is closer to about 1/4 MOA and windage is closer to about 1 MOA.
Make sure you have a very stable shooting platform and you are using the ammo you wish to have zeroed to the gun. Different ammo will have a different trajectory and your zero will be different. Also note that once the optic is removed from the gun we recommend confirming zero once the optic is remounted to the gun. The same is true if you were to drop the gun in the field, if you were to travel to a place with much different environmental conditions, or if you were to change certain parts on your gun (Muzzle device, gas system, etc.).
You can fire your first group at this point. We recommend taking oneinital shot to get an idea of how much adjustment will be needed. If you do decide to shoot at 10 yards and you have a 5.56 AR15 with our standard height mount your impact should be roughly 2.5 inches below your point of aim for a 200 yard zero. Once you are on or close at 10 yards you should move the target to the desired distance and make any additional adjustments needed.
Once you have completed all your necessary adjustments you can press the joystick inward to save the zero. It will take you to a screen that says 'save' at the top. Press the joystick upward to save. The unit will confirm it is saved and take you back to the 'zeroing' menu. You can go back and exit the menus at this point.
The device has the ability to enter multiple zeros under one profile. Perhaps it is better not to do this, as this can add a lot of confusion. Therefore, add only one distance to the each profile if you use only one gun. The profile will always be by default at the first distance below it, and now there is a way to quickly switch.
