TROUBLESHOOTING
Scope w ill not turn on.
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 “ON” button (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).

Your Night Vision device offers a Built-In Infrared Illuminator. This allows you to
see in complete darkness where no ambient light source, such as moonlight, is
available. To activate, simply press the button (3) located next to the “ON” button.
Direct the device at an object at a distance approximately 100 yards and rotate the
eyepiece (4) to give the best quality image. After the adjusting, do not rotate the
eyepiece any longer irrespective of the distance and other conditions.
