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 caps closed!) 

Condensation accumulates on the parts. 

 

It is O.K. to use the unit in cold. However, when the unit is brought 
from the cold into a warm environment, it has to warm up for up to 2 
hours (not minutes!). Only then it is allowed to turn it 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 
binoculars away from the light source immediately. The image should 
be restored in within 2 minutes. 

 

Poor atmospheric conditions such as fog, haze or extremely dark 
environments will decrease the visibility distance of the unit.
