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
p roducts amplify existing light, allowing you to see in dark
conditions too dark for the naked eye.
This rugged water-resistant night vision device uses advanced technology and fiber
optic bundles to eliminate distortion thus providing excellent resolution, superior
image quality, and a flat field of view.
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.
Your Night Vision device is ideal for a variety of professional and recreational uses
including the following:
• Wild Life Observation
• Search and Rescue
• Astronomy
• Security
• Boating / Marine Use
• Property Management
• Police / Law Enforcement
GETTING STARTED
Installing Batteries
This device operates on two AA batteries. To install, remove 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.
Use and Testing
This device operates on two AA batteries. Make sure they have been installed
according to the instructions above.
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.
If testing or using the device in the dark, remove the objective lens cap and activate
the device by pushing the “ON” button (2).
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.
Direct the device at the subject to be viewed and adjust the final focus by rotating the
objective lens focusing ring until the image quality is optimal.
The Green LED indicates that the light amplifier unit is on. The Red LED indicates that
the Infrared Illuminator is on. Always remember to turn the unit off when done. Do
not store this device while the indicators are lit.
Caution: This device can be used in extreme cold weather. However, when the unit
is brought back into a warm environment, you must wait approximately 5 hours before
using the unit again. Damage may occur due to condensation that may have
accumulated on the internal circuitry of the unit.
Spots In The Image
You may see spots in the image. These vary from device to device and are cosmetic
blemishes inside the device. These are normal for Night Vision devices and are NOT
a defect.
TROUBLESHOOTING
Scope will not turn on.
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.
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.
The scope may flash when used in a bright environment. It may also flash during the first
few seconds of use in dark enviro n m e n t s.
CARE AND MAINTENANCE
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:
• 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.
• 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, and moisture.
• 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 pro f e s s i o n al lens cleaning supplies.
• Clean the exterior of the device with a soft clean cloth.
