Congratulations on the purchase of your Bushnell Night Vision Product.  
Bushnell Night Vision products are comprised of high quality image  
intensifier tubes and optics. Bushnell Night Vision products amplify existing  
light, allowing you to see in dark conditions too dark for the naked eye.  
Check that the batteries are installed properly. Replace the batteries with new  
ones. Check the battery contacts to ensure they are clean and free of corrosion.  
Check that the power is in the “ON” position.  
Image is not focused.  
Adjust the focus on the Eyepiece (4). Adjust the Objective Lens Focusing Ring.  
If still no improvement, clean the lenses; they may be foggy or dusty.  
HOW NIGHT VISION WORKS  
Bushnell Night Vision products collect and amplify existing light through the  
objective lens, which is then focused on the image intensifier. Inside the intensifier,  
a photocathode is “excited” by the light and converts the photon energy into  
electrons. These electrons accelerate across an electrostatic field inside the  
intensifier and strike a phosphor screen (like a green monochrome TV screen)  
which emits an image that you can see. It is the acceleration of electrons, which  
provides gain and enhances the image. This is a Generation I device.  
Visibility decreases or disappears.  
Bright light sources such as headlights may cause visibility to degrade or disappear  
completely. Turn the Power OFF (2) and turn the scope away from the light source.  
The unit will restore itself in 1 or 2 minutes. Conditions such as fog or extremely  
dark environments will decrease visibility.  
Scope flashes.  
Your Night Vision device is ideal for a variety of professional and recreational uses  
including the following: Wild Life Observation, Astronomy, Boating / Marine Use,  
Police / Law Enforcement, Search and Rescue, Security, Property Management  
The scope may flash when used in a bright environment. It may also flash during  
the first few seconds of use in dark environments.  
CARE AND MAINTENANCE  
GETTING STARTED  
Your Bushnell Night Vision device was designed to provide many years of reliable  
service. To ensure that you get the most enjoyment out of your Night Vision device,  
always obey the following warning and precautions:  
Installing Batteries  
This device operates on two AA batteries.  
To install, unscrew the battery compartment  
cover located on the bottom of the unit.  
Insert the batteries into the battery  
compartment so that the (+) and negative (-)  
terminals of the batteries match the markings  
inside the compartment. Replace the battery  
cover carefully – do not over tighten.  
• Do not point this device toward any light source greater than 1 lux such as car  
headlights, for an extended period of time. This device utilizes an internal flash  
protection system which minimizes potential damage, but long-term  
exposure to bright lights can damage the unit. Any such damage may void  
your warranty.  
This device was designed to be self-contained. Do not open the body of  
the device or otherwise attempt to service this device.  
Use and Testing  
This device operates on two AA batteries.  
Make sure they have been installed according  
to the instructions above.  
• Always store the device in a dry, well-ventilated room.  
• Remove the batteries if the device is to be stored for longer than 2 months.  
Keep the device away from any heating and air conditioning vents or other  
heating devices, direct sunlight, nd moisture.  
If you wish to test your night vision device in  
a lighted area, be sure the objective lens cap  
is covering the objective lens (1) prior to  
pressing the “ON” button (2). The objective  
lens cap has a pinhole opening to admit a small amount of light for testing  
purposes.  
• Avoid dropping or otherwise shocking the unit. Although designed for  
rugged outdoor use, this device incorporates a sophisticated optica system,  
which could be damaged in extreme cases of misuse.  
• Clean the optical lenses with professional lens cleaning supplies.  
• Clean the exterior of the device with a soft clean cloth.  
If testing or using the device in the dark, remove the objective lens cap and activate  
the device by pushing the “ONbutton (2).  
Set the preliminary focus adjustment by placing the adjusting mark (located on top  
of the objective focusing ring) opposite the letter “N” in the word “Normal” (6).
