User manual BUSHNELL NIGHT VISION 26-2024

[. . . ] 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. [. . . ] 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 until the image quality is optimal. This device can be mounted on any tripod with a 1/4" tripod socket (5). 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. 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. 2 3 6 1 5 4 7 TROUBLESHOOTING Scope will not turn on. Check the battery contact to ensure it is clean and free of corrosion. If still no improvement, clean the lenses; they may be foggy or dusty. Bright light sources such as headlights may cause visibility to degrade or disappear completely. Conditions such as fog or extremely dark environments will decrease visibility. It may also flash during the first few seconds of use in dark environments.
