The Pulsar Thermion thermal scope is designed for easy, “one-shot” zeroing or
sighting-in. Sighting in your rifle makes your point of impact (POI) match your point
of aim (AP) so your rifle is accurate.
Mount the Thermion on your rifle, and set your rifle on a shooting rest, bipod or tripod.
Aim at center-mass on your target at a known distance and take one shot.
Long press (press and hold) the controller button to access the main menu.
Rotate the controller ring to highlight the "Zeroing" submenu.
Confirm your selection with a short press of the controller button.
Select the appropriate distance listed in the "Zeroing" submenu. Confirm your selections with a short press of the controller button.
Select the "+" icon. Enter the distance setting you prefer by short pressing the controller button and rotating the controller ring to enter the desired distance.
Once entered, long press the controller button to back out to the zeroing menu.
Select the zeroing distance by short pressing the controller button.
Select the cross with center dot icon from the menu using the controller ring. This accesses a new menu that lets you set up the zeroing parameters.
Rotate the controller ring to highlight the "Freeze" option (annotated by a snowflake icon) and select it with a short press.
With the display image frozen, navigate up to the "Windage/Elevation" icon with the controller ring and select it with a short press of the controller button.
Use the controller ring to move the white "X" to where it covers the POI. A short press of the controller-button will toggle between the X and Y axis.
Once the white "X" is over the original POI, long press the controller button to back out of the adjustment mode. Long press the controller button again to save your zeroing parameters.
Take another shot to confirm zeroing. If necessary, repeat steps 6 – 10.
