Scens
Scens can be Default, Outdoor, Polar, or Rainforest. Specifically, Outdoor is the initial mode; Outdoor is mainly suitable for environments with fewer outdoor thermal targets to highlight thermal targets; Polar is suitable for scenes with low ambient temperature, like winter; Rainforest is suitable for scenes with high ambient temperature and high humidity.

Reticle

• Reticle allows setting options like Reticle Display, Reticle Color and Reticle Movement. Reticle Display allows displaying or hiding the reticle. When the reticle is displayed, the color and position of the reticle can be set.
