Objective Lens
A canted objective lens is part of the design of reflex/reflective optical sights. In order to create a proper reflection of the reticle/dot the objective lens must be perpendicular to the LED. Because the LED is mounted to the base of the optic the objective lens will be canted back, towards the LED.

Battery
Our Solar Fail Safe dual power system (solar cell and internal battery).
Multi Reticle
The default reticle for this sight is a 2MOA dot centered in a 32MOA circle with three positioning points. The diameter of the circle reticle represents approximately 32" at 100 yards (81cm at 100meters). Hold the " ▲ " button down for 3 seconds to switch between the three reticle options, Circle+Dot, Dot-only and Circle-only, in that order.

Installation on a Slide
• Place the red dot on a compatible slide cut or adapter plate.
• Use either the included screws tighten to 15 INCH/ lbs.

Sight Operation
• Two power supply modes (battery power supply mode and solar power supply mode).
• Press the ▲ key briefly to turn on the device, hold the ▼ key for 3 seconds to turn it off, and hold the ▲ key for 3 seconds to switch the pattern.
• Press the ▲ key and the ▼ key simultaneously to switch the power supply mode (when entering the solar power supply mode, the LED will flash rapidly three times; when entering the battery power supply mode, the LED will flash rapidly twice).
• In battery-powered mode: There are a total of 10 brightness levels (1 and 2 night vision levels). Pressing the ▲ key increases the brightness, while
• pressing the ▼ key decreases it.
• In solar power supply mode, the brightness automatically changes according to the ambient light.
■ Special operation:
1) Solar cell power: If the battery voltage is below 2.2V, please replace it. The sight will still operate if there is sufficient ambient light for the solar cell.
2) To reduce power consumption when you have low battery and/or low ambient light, you can toggle the 32MOA circle OFF by holding the “ ▼ ” button for about 3 seconds.
Note:
1) Memory function: The sight will remember the last saved brightness setting when powered on and off.
2) Low battery Warning: If the battery voltage is below 2.2V, the reticle will blink slowly.
Multi - Reticle
The multi-reticle variant provides 3 reticle options, including a 2 MOA center dot.
At 50 yards, a 2MOA dot is 1’’, or 2 MOA is 2’’ at 100 yards.
When changing between reticle options, your subtensions will not change. This allows for reliability and versatility across firearm platforms.

Zero Setting
• This sight has been factory adjusted to an approximate 25 yard zero and should require minimal adjustment to achieve zero.
• The Elevation adjustment is located on top of the tail section of the housing and the Windage adjustment is located on the right side of the housing. Adjustment can be performed by inserting the flat-tipped end of the included tool into the turret slot and rotating.
• Windage and Elevation adjustments are approximately 1 MOA per click.
• Each adjustment click has a value of approximately 1 MOA or 1 inch at 100 yards (1/ 2" at 50y; 1/4" at 25y). When zeroing at 25 yard, if your impacts are 2 inches low and 1 inch right, you will need to adjust Elevation 8 clicks UP (counterclockwise) and 4 clicks LEFT (clockwise).
Caution: If you feel the knobs can no longer be rotated, you may have reached the mechanical limit of the adjustment turret. Do not try to rotate the knobs further if you feel a bind or you may cause damage.
Parallax
Cuinfi® 1x26 is designed to be parallax free at 33 yards. At distances closer than 33 yards, parallax erroris very minimal and willnot lead to appreciable point of impact shift. At distances past 100 yards, some parallax will be observed. When using your sight at close range, keep in mind that the entire window is available for aiming. If you can perceive the reticle anywhere in the window, you can use it as a point of aim. For shooting past 100 yards, keeping the reticle more centered in the window will result in more consistent hits on target.
Cuinfi 50,000 Round Guarantee
If your optic fails prior to firing off 50,000 live fire rounds, we will repair or replace it for free. Nope, we’re not tracking shot data. We’ll go by the warrior honor code and your best estimation on whether or not the optic failed prior to using it for at least 50,000 rounds.
