We have included a USB (type C) charging cable with your scope. Plug the cable into a USB wall charger that has an output of 2 amps (Wall Charger not included).

ON / OFF
To Turn On the device press and hold the Power button until you see the ATN Homescreen.
To Turn Off the device press and hold the Power button.
If the scope freezes or stops responding to the control panel. Press and hold the Power button for 15 seconds to reboot the scope.
Using your keypad
The keypad is programmed to be used in two different ways:
- Short and Quick Taps — used for most functions and to navigate the menu.
- Press and Hold — designed to be used in the following situations — On/Off, Menu.
By rotating the Diopter Adjustment Ring you will achieve optimal sharpness for your vision. Look through the eyepiece, focusing on the reticle and widgets on the screen. Rotate the diopter adjustment until the reticle and widgets are perfectly sharp in appearance.
Once the Diopter Adjustment is set to your liking, adjustment will not need to be performed unless another user altered the focus for their needs.
Rotate the Adjustment Ring, as necessary, to achieve the proper focus at various distances.
Mounting your scope
Make sure your weapon is not loaded. Use safe weapon handling procedures at all times.
The ThOR LT has a 3-inch eye relief, and can be mounted using 30 mm mounting rings (not included). Place the scope on the bottom half of the rings you just mounted to the weapon’s rail, verifying you have sufficient eye relief for your platform. Place the top portion of your ring over the mounted bottom portion, make sure the holes align and the screws turn easily. Apply equal torque to all screws. Make sure your rings are tight on your rifles rail and will not come loose due to recoil.
OPERATION WITH KEYPAD
- On/Off button; A long press of this button (1–2 seconds) will either power on the unit or power off the unit, depending on the current status of the scope.
- Up button; A short press of this button will cycle you through your change in zoom (3–6x or 4–8x).
- Left button; A short press will allow you to preform a contrast image cycle change (1 → 2 → 3 → 1).
- OK button; A short press of this button will perform a manual NUC. A long press (1-2 seconds ) will open the Menu.
- Right button; A short press allows you to adjust the brightness of your micro display screen (100% → 60% → 30% → 10%).
- Down button; A short press will change your thermal mode from White Hot to Black Hot.
The first screen you’ll see after turning on the device is the Homescreen. It consists of Scales, Status Bar icons and different Information Widgets.
- Roll Scale shows the rifles cant based on internal 3D Gyroscope.
- Pitch Scale shows rifle inclination based on internal 3D Gyroscope.
To open the Menu, perform a long press of the OK button (1 to 2 sec) until you see the Menu appear on the left side of the screen. You will see the following Icons:
NUC. This feature allows you to turn On/Off the auto NUC feature.
PIX. This feature is intended to correct neutral pixels in the display. Select the option by using the OK button when PIX is highlighted.
Move the dot to the area of the display with the neutral pixel, and place the flashing dot directly over the neutral pixel. A short press of the OK button will select that pixel for repair. After the short press of the OK button to select the pixel for repair, a long press of the OK button will exit the pixel correction mode.
RET. This option allows you to select one of four reticles available in the scope.
SENS. This option gives you the ability to adjust the thermal sensitivity of your scope.
ZERO. This options gives you access to the One Shot Zero, in order to Zero your reticle to your weapon.
You will need to obtain a target that is able to be detected by a thermal imager. ATN has thermal targets available for purchase, or you can use any of the following items: Cold or Hot water bottle, hand warmers, or foil based tape.
We recommend using a boresight device in order to get on target faster. Once the scope is aligned with a boresight, follow the One Shot Zero procedure in order to Zero the scope to your weapon.
To Zero your scope you will need to go to the Zero section of the Menu. Press and hold the OK button until the menu appears in the sidebar of the display. Use the Down button to navigate to the Zero option in the menu.
Press the OK button to enter zero mode.
You will see on your display two reticles. One will move via use of your keypad, the other will remain stationary. While keeping the gun as steady as possible, fire a round. Using the key pad, move the red reticle to the point of impact while keeping the black reticle on the original point of aim at which you fired the shot. Once you have placed the center of the red reticle on the POI, short press the OK button to save the zero. If you feel confident that you have the best possible zero, a long press of the OK button will exit the menu and return to the Homescreen. If you need to fine tune the zero you can refer to the previous instructions to fine tune the zero.
Although you may not need more than one shot to Zero your scope, we do recommend that you fire additional shots once the initial zero process is complete to insure the optic and weapon are truly Zeroed. If additional corrections need to be made to fine tune the zero, then make those corrections as needed.
How to perform a NUC
NUC’ing helps to improve the image quality when the image is degraded by various environmental factors. There are multiple NUC tables that span the full operating temperature range, and the scope automatically selects the optimum table based on its temperature.
You can set the system to perform a NUC automatically at a predefined time interval. Or, you can turn the automatic NUC off and NUC the system manually, when required. Also, you can use the NUC shortcut from the Homescreen by quickly pressing the OK button anytime.
Example: Change of temperature, continuous viewing of a particular warm object, and movement from one environment to another all may cause image degradation.
In order to turn the automatic NUC On or Off. Press and hold the OK button for the menu to display. Using your Down Arrow button, scroll to NUC. Press the OK button to enter the NUC menu. Press the Up button to cycle the NUC On or Off. Press and hold the OK button to exit the Menu. You can also manually NUC the scope from the Homescreen by quickly pressing the OK button.
Reticle style adjustment
You can select the reticle style in the System Menu.
To enter the System Menu, open the Menu by pressing and holding the OK button, use the Down Arrow button to select RET. Press the OK button to enter the Reticle Menu. Once there, use the Up and Down Arrow buttons to select the reticle you like. Press the OK button to save your selection. To Exit the Menu, press and hold the OK button.
CONTRAST — the difference in luminance and color that makes an object more distinguishable. You can change the contrast by quickly pressing the Left Arrow button to cycle through the preset contrast settings.
THERMAL SENSITIVITY — Allows you to select how sensitive the Thermal Sensor is in picking up thermal heat signatures.
In order to change the Thermal Sensitivity, press and hold the OK button.
When the Menu appears, use the Down Arrow to select SENS. Press the OK button to enter the Thermal Sensitivity Menu. Press the Up button to cycle through the sensitivity options. Once you select the Thermal Sensitivity you would like to use, short press the OK button to save your selection. Press and hold the OK button to exit the Menu.
