ATN Viper manual Headgear, Figure H1

Page 5

You may need to focus the 35mm camera or video camera in combination with the Viper in order to get the sharpest possible image.

We suggest that you find an open space to work in. Focus the Viper so that the scene is at its sharpest. For best results you should disable the auto focus (if any) on either the 35mm camera or the video camera and manually focus the 35mm camera or the video camera. Once the image is sharp, then simply adjust the Viper’s front lens to change the focus.

An important part to remember is that you are not taking a picture of an object that is far away from you, but you are actually taking a picture of the phosphorous screen of the Viper that is only 2-3 inches away.
