3.6 Eyepiece adjustment
[Eyepiece adjustment]
The eyepiece adjustment is performed before
target sighting.
Remove the telescope lens cap.
Point the telescope at a bright object, and rotate
the eyepiece ring full counter-clockwise.
Look through the eyepiece, and rotate the
eyepiece ring clockwise until the reticle
appears as its maximum sharpness.
When looking into the eyepiece,avoid an intense
look to prevent parallax and eye fatigue.
When it is hard to see the reticle due to poor brightness,
press [ILLU] to illuminate it .
For adjusting intensity of brightness, refer to "4-4 Adjusting Reticle Illumination”.
3.7 Target sighting

condition.There is a slight possibility of focusing failure owing to brightness,
contrast, the shape and size of the target.
In such a case, press the AF button and focus on the target by operating the
Power focus key or the AF ring.
