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.
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.
GETTING STARTED
Installing Batteries
• Slide the top battery cover (a) rearward and insert two AA batteries
per the polarity indicators, and then slide the battery cover back
onto the unit.
Using The Power Button And
I n f r a red LED Illuminator
• Never turn the scope on in
daylight conditions with the
lens cap (b) off. The pinhole in
the lens cap allows you to test
the scope in daylight conditions.
• To turn on the device, slide
the power button (c) to the
"ON" position.
• To turn on the IR (d) (Infrared Illuminator), slide the IR button to
the "ON" position. Your Bushnell Night Vision product includes a
built-in infrared illuminator. This allows you to see in complete
darkness when no ambient light source is available.
• After the device has been changed from the ON position to the
OFF position, the image will slowly fade out. This is normal and is
not a defect.
To Focus
• First, turn the Objective Lens Focusing Ring (e) to infinity. (Full
clockwise as shown in the drawing).
• While looking at a distant object (at least 20 ft. away), adjust the
Eyepiece Focusing Ring (f) for the sharpest image.

• Once the Eyepiece Focusing Ring is adjusted, you need only adjust
the Objective Lens Focusing Ring as needed.
Spots In The Image
• You may see spots in the image. These vary from scope to scope and
are cosmetic blemishes inside the scope. These are normal for Night
Vision Scopes 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 Focusing Eyepiece. Adjust the Objective Lens
Focusing Ring. For a focused image, you must be at least .5 feet away
from the object you are viewing. If still no improvement, clean the
lenses; they may be foggy or dusty. (See To Focus).
Visibility decreases or disappears.
Bright light sources such as headlights may cause visibility to
degrade or disappear completely. Turn the Power OFF 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 environments.
CARE & MAINTENANCE
• When not using for an extended amount of time, remove batteries
and store the product in a dry location.
• Avoid turning the product on in extremely bright light conditions.
• Handle this product like you would a camera. Though Bushnell
Night Vision products are durably constructed, the image
intensifier tube consists of glass and is subject to breakage.
• Keep the optics clean. We recommend using a camera cleaner kit to
clean the outside of the objective and eyepiece lenses. Follow the
directions with the kit.
• Do not disassemble this product. Unauthorized disassembly not
only voids the warranty but may also cause damage from the lack
of special tools and techniques.
