Lens loading and unloading
Align the red dot of the lens with the red dot in the instrument, carefully insert it to the end, and
rotate it clockwise (in the direction of the red arrow) for about 50 ° until it cannot be rotated (there
is a sense of positioning), and the installation is completed.
When removing, turn the lens counterclockwise (in the direction of the red arrow) to the end, and
then take it out carefully.
