8. TROUBLESHOOTING
The scope does not work.
- Check that the batteries are installed properly.
- Check the charge of the batteries. Replace if they are weak. Do
not use old batteries with new ones.
The image does not appear in focus.
Bring the inspected object to the center of the image. Turning the
objective lens ring (7), and/or the eyepiece (2) adjust to achieve
the clearest image on the screen. Repeat the steps of focusing if
necessary
If the view still does not seem in focus, clean the lenses; they
could be foggy or dusty.
Unit flashes
It is normal for the unit to flash within the first 2 minutes of
activation. If the flashing continues afterwards the following is a
possible cause: bright environment (even with the cap closed!)
Condensation accumulates on the parts.
It is O.K. to use the scope in cold. However, when the unit is
brought from the cold into a warm environment, it has to
warm up for up to 5 hours (not minutes!). Only then should it be
turned ON again.
Visibility decreases and / or disappears.
Bright light sources (moon, projectors or headlights) may cause
visibility to degrade or even completely disappear. Move the
scope away from the light source immediately.
