NIGHT VISION  
Place headphone in ears and activate the DSAS microphone by depressing the  
“ONbutton (6).  
INSTRUCTIONS  
If the subject is to be viewed in a completely dark area where no ambient light  
source (such as moonlight) is available, activate the Infrared Illuminator by pressing  
the Infrared Illuminator button (5) located next to the “POWER” button. Direct the  
device at an object at a distance approximately 100 yards and rotate the eyepiece  
(7) 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.  
Adjust sound amplification volume to an optimal level by pressing the volume  
control buttons (8). If the sound is to be recorded, insert the tape recorder plug  
into the jack (9) and start recording.

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.  
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.  
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.  
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  
Your Night Vision device offers a Directional Sound Amplification System (DSAS),  
providing you with the added benefit of a highly sophisticated sound amplification  
system. DSAS utilizes the latest developments in electronic sound amplification by  
combining our exclusive high sensitivity DIRECTIONAL microphone with a state of  
the art noise reduction system, providing unparalleled sound enhancement.  
Scope w ill 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.

Image is not focused.  
Adjust the focus on the Eyepiece (7). Adjust the Objective Lens Focusing Ring.  
If still no improvement, clean the lenses; they may be foggy or dusty.  
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  
Visibility decreases or disappears.  
Bright light sources such as headlights may cause visibility to degrade or disappear  
completely. Turn the Power OFF (4) 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.  
GETTING STARTED  
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.  
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.  
The sound amplification system is not amplifying properly.  
Make sure the DIRECTIONAL antenna is tightly connected to the microphone.  
Check your headset connection; make sure your batteries are fresh.

This device operates on two AA batteries.  
Make sure they have been installed according  
to the instructions above.  
Your Bushnell Night Vision device was designed to provide many years of reliable

headphone plug into the audio output jack  
(2). If you wish to test your night vision device  
in a lighted area, be sure the objective lens cap is covering the objective lens (3)  
prior to pressing the “POWER” button. The objective lens cap has a pinhole  
opening to admit a small amount of light for testing purposes.  
• 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.  
If testing or using the device in the dark, remove the objective lens cap and activate  
the device by pushing the “POWER” button (4).  
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.
