Calibration Mode

Calibration mode selection.

Calibration allows you to equalize the temperature background of the microbolometer and eliminate the thermal image flaws (such as vertical bars, phantom images, grainy field of view, etc.).

There are three calibration modes: manual, semi-automatic and automatic.

The selected calibration mode is displayed in the status bar (see Status Bar section).


Select the required mode in the Calibration Mode item:

  1. Press and hold the controller button (6) to enter the main menu.
  2. Rotate the controller ring (6) to select the Calibration Mode  menu item.
  3. Press the controller button (6) briefly to enter the Calibration Mode submenu.
  4. Rotate the controller ring (6) to select one of the calibration modes described below.
  5. Press the controller button (6) briefly to confirm your selection.

M mode (manual)

  • Close the lens cover (12) and press the ON/OFF (14) button briefly.
  • Open the cover after the calibration is completed.

SA mode (semi-automatic)

  • The user independently determines the need for calibration (according to the thermal image being observed).
  • Press the ON/OFF (14) button briefly to activate calibration.
  • There is no need to close the lens cover (internal shutter covers the microbolometer).

A Mode (automatic)

  • The riflescope is calibrated autonomously according to the software algorithm.
  • There is no need to close the lens cover (internal shutter covers the microbolometer).
  • In this mode, the riflescope may be calibrated by the user with the ON/OFF (14) button.
  • A countdown timer will appear instead of the calibration icon when in automatic calibration mode with 3 seconds remaining until automatic calibration.

Note: a display thermal image freezes until the calibration is in progress.
