4 TROUBLE SHOOTING
4.1 The red dot does not appear or has disappeared
Clean contact surfaces in the battery compartment and verify that the battery (2)
is working and that it is installed correctly. Verify that the battery cap (1) is rmly
tightened.
4.2 The sight is impossible to zero
If an adjustment screw (5) (6) is at its limit, check the alignment of mount and
barrel. If point of impact is moving, check the stability of mount.
4.3 The red dot does not appear to be round
Most likely the result of how your eye perceives the red dot. Look at the red dot and
slowly rotate the sight. If the aberration in the shape of the red dot does not rotate
with the sight, the irregularity is caused by how your eyes percieves the red dot.
Minimize this eect by always setting the intensity of the red dot to the lowest set-
ting where the red dot is clearly visible against the target in relation to ambient light.
