The image diminishes or disappears
Excessive light (moonlight, spotlights or projectors) can
lead to faulty imaging. Move the scope away from the
light source immediately. The image will be restored wit-
hin a period of two minutes.
Imaging results can also only be achieved at short
distances if there is severe fog, haze or under extremely
dark conditions.
Black dots in the visual field
When you view the image of your Night-Vision scope
through the eyepiece you may perceive small black dots.
This is not a quality fault but a typical feature of night-
vision equipment of this type.
Light power of image tube lessens
The light power of the image tube decreases in the course
of its service life. When the Night-Vision scope is used
correctly the service life is approximately 10,000 hours.
The service life is reduced if the Night-Vision scope is
exposed to strong light sources such as street lamps or
headlights/spotlights.
The image tube is defective
The image tube is subject to natural wear.
If the light amplification of the image tube becomes
less, please send your Night-Vision scope directly to the
MINOX Customer Service where a new image tube can
be inserted, if neccessary.
