The scope flickers, flashes or “snows”.  

The scope may flicker or flash when used in a bright environment; to correct this, place the cap over 
the objective lens and enter a dark environment. The scope will restore itself to a natural functioning 
state in several minutes or hours, depending on how long the scope had been exposed to the light.    
The scope may flicker for the first several seconds of use, even when in a dark environment, before the 
scope corrects itself and functions properly.  
The scope may “snow” for several minutes after being exposed to a bright light source (daylight, a car's 
headlights, fire, etc.) even if being operated in complete darkness.  
 

 

The image is not focused.  

Adjust the focus of the eyepiece and the objective (see “Use and Testing” section). Check that the 
lenses are not foggy or dusty; if they are, carefully clean the external surfaces of lenses with a soft 
cotton fabric. Replace the battery if the total battery charge is less than 2.2V.  
When the unit is brought into a warm environment from a cold one, condensation may appear on the 
internal lenses; you must wait two hours before using the unit.  
 

 

Visibility decreases or disappears. 

Bright light sources, such as headlights, may cause visibility to decrease or disappear and the image to 
flicker. Turn the power off and turn the scope away from the light source; visibility will restore itself in 
several minutes.
