INFRA-RED ILLUMINATOR
Infra-red illuminators, or IR illuminators, are common to night vision. The IR
light greatly enhances the performance of the Viper while remaining almost
totally invisible to the naked eye. The IR illuminator on the Viper is located
underneath the front lens, next to the battery compartment.
When you turn the scope on the IR will automatically turn on. It is impor-
tant to remember that the IR illuminator is simply an infra red light source,
and like any light source, it may loose its effectiveness over a great dis-
tance.
NOTE: The IR will automatically turn off when the unit’s main power switch is turned off.
USING THE 4X TO 8X DOUBLER
(opti on al)
Unscrew 35 mm lens off the body of the Viper (make sure that the unit is turned off). Screw the
doubler into the body of the Viper where the 35 mm lens was removed. Screw the 35 mm lens
or your 90 mm lens into the doubler.
NOTE: You can also add just the 90mm lens to a Viper without a doubler.
NOTE: When attaching the doubler do not be afraid to use a little force.
USING THE CAMERA ADAPTER (optio na l)
To use your Viper with a 35mm camera or camcorder you will need the following:
1) If you plan to use a camcorder, then your camcorder must have a MACRO feature. Most
modern camcorders today have a MACRO feature built-in.
2) If you plan to use a 35mm camera, you will need a MACRO lens. If you don’t have one, we
advise that you contact your local camera store.
3) You may or may not need a STEP-UP or STEP-DOWN ring in order to adapt the camera
adapter to your lens.
NOTE: The camera adapter comes with 37mm and 52mm threads. If you need other sizes your
local camera store should be able to help.
• Remove the rubber eyecup from the Viper
• Screw the camera adapter onto the front of the lens on your Video camera’s lens or your
35mm camera’s lens.
• Loosen the three set screws on the camera adapter.
• Place the camera adapter over the Viper’s eyepiece.
• Tighten the three set screws to fit snugly to the Viper’s eyepiece
