ILLUMINATOR OPERATION
OFF
Press the button that is closer to the eye (marked "+") to turn on reticle
illumination. Press the same button repeatedly to increase the illumination
level incrementally or hold the button to increase the level continuously for
approximately 7 seconds until the maximum illumination is reached and the
reticle starts flashing. Similarly, press the button that is further away from the eye
(marked "-") to reduce the illumination level.
In a similar way, use the button located further away from the eye (marked "-"
to turn on and control the night mode (without the use of an additional night
vision devices, the brightness level is mostly invisible to the naked eye). The
brightness adjustment procedure is identical to that used in the daytime mode.
